## Command line arguments

       Standard (Mandatory) qualifiers:
      [-sequence]          seqall     Sequence(s) filename and optional format, or
                                      reference (input USA)
      [-outfile]           outfile    [*.showfeat] Output file name

       Additional (Optional) qualifiers:
       -matchsource        string     [*] By default any feature source in the
                                      feature table is shown. You can set this to
                                      match any feature source you wish to show.
                                      The source name is usually either the name
                                      of the program that detected the feature or
                                      it is the feature table (eg: EMBL) that the
                                      feature came from.
                                      The source may be wildcarded by using '*'.
                                      If you wish to show more than one source,
                                      separate their names with the character '|',
                                      eg:
                                      gene* | embl (Any string is accepted)
       -matchtype          string     [*] By default any feature type in the
                                      feature table is shown. You can set this to
                                      match any feature type you wish to show.
                                      See http://www3.ebi.ac.uk/Services/WebFeat/
                                      for a list of the EMBL feature types and see
                                      Appendix A of the Swissprot user manual in
                                      http://www.expasy.ch/txt/userman.txt for a
                                      list of the Swissprot feature types.
                                      The type may be wildcarded by using '*'.
                                      If you wish to show more than one type,
                                      separate their names with the character '|',
                                      eg:
                                      *UTR | intron (Any string is accepted)
       -matchtag           string     [*] Tags are the types of extra values that
                                      a feature may have. For example in the EMBL
                                      feature table, a 'CDS' type of feature may
                                      have the tags '/codon', '/codon_start',
                                      '/db_xref', '/EC_number', '/evidence',
                                      '/exception', '/function', '/gene',
                                      '/label', '/map', '/note', '/number',
                                      '/partial', '/product', '/protein_id',
                                      '/pseudo', '/standard_name', '/translation',
                                      '/transl_except', '/transl_table', or
                                      '/usedin'. Some of these tags also have
                                      values, for example '/gene' can have the
                                      value of the gene name.
                                      By default any feature tag in the feature
                                      table is shown. You can set this to match
                                      any feature tag you wish to show.
                                      The tag may be wildcarded by using '*'.
                                      If you wish to show more than one tag,
                                      separate their names with the character '|',
                                      eg:
                                      gene | label (Any string is accepted)
       -matchvalue         string     [*] Tag values are the values associated
                                      with a feature tag. Tags are the types of
                                      extra values that a feature may have. For
                                      example in the EMBL feature table, a 'CDS'
                                      type of feature may have the tags '/codon',
                                      '/codon_start', '/db_xref', '/EC_number',
                                      '/evidence', '/exception', '/function',
                                      '/gene', '/label', '/map', '/note',
                                      '/number', '/partial', '/product',
                                      '/protein_id', '/pseudo', '/standard_name',
                                      '/translation', '/transl_except',
                                      '/transl_table', or '/usedin'. Only some of
                                      these tags can have values, for example
                                      '/gene' can have the value of the gene name.
                                      By default any feature tag value in the
                                      feature table is shown. You can set this to
                                      match any feature tag valueyou wish to show.
                                      The tag value may be wildcarded by using
                                      '*'.
                                      If you wish to show more than one tag value,
                                      separate their names with the character
                                      '|', eg:
                                      pax* | 10 (Any string is accepted)
       -sort               menu       [start] Sort features by Type, Start or
                                      Source, Nosort (don't sort - use input
                                      order) or join coding regions together and
                                      leave other features in the input order
                                      (Values: source (Sort by Source); start
                                      (Sort by Start position); type (Sort by
                                      Type); nosort (No sorting done); join (Join
                                      coding regions together))
       -annotation         range      [If this is left blank, then no annotation
                                      is added.] Regions to annotate by marking.
                                      If this is left blank, then no annotation is
                                      added.
                                      A set of regions is specified by a set of
                                      pairs of positions followed by optional
                                      text.
                                      The positions are integers.
                                      They are followed by any text (but not
                                      digits when on the command-line).
                                      Examples of region specifications are:
                                      24-45 new domain 56-78 match to Mouse
                                      1-100 First part 120-156 oligo
                                      A file of ranges to annotate (one range per
                                      line) can be specified as '@filename'.

       Advanced (Unprompted) qualifiers:
       -html               boolean    [N] Use HTML formatting
       -[no]id             boolean    [Y] Set this to be false if you do not wish
                                      to display the ID name of the sequence.
       -[no]description    boolean    [Y] Set this to be false if you do not wish
                                      to display the description of the sequence.
       -[no]scale          boolean    [Y] Set this to be false if you do not wish
                                      to display the scale line.
       -width              integer    [60] You can expand (or contract) the width
                                      of the ASCII-character graphics display of
                                      the positions of the features using this
                                      value.
                                      For example, a width of 80 characters would
                                      cover a standard page width and a width a 10
                                      characters would be nearly unreadable.
                                      If the width is set to less than 4, the
                                      graphics lines and the scale line will not
                                      be displayed. (Integer 0 or more)
       -collapse           boolean    [N] If this is set, then features from the
                                      same source and of the same type and sense
                                      are all printed on the same line. For
                                      instance if there are several features from
                                      the EMBL feature table (ie. the same source)
                                      which are all of type 'exon' in the same
                                      sense, then they will all be displayed on
                                      the same line. This makes it hard to
                                      distinguish overlapping features.
                                      If this is set to false then each feature is
                                      displayed on a separate line making it
                                      easier to distinguish where features start
                                      and end.
       -[no]forward        boolean    [Y] Set this to be false if you do not wish
                                      to display forward sense features.
       -[no]reverse        boolean    [Y] Set this to be false if you do not wish
                                      to display reverse sense features.
       -[no]unknown        boolean    [Y] Set this to be false if you do not wish
                                      to display unknown sense features. (ie.
                                      features with no directionality - all
                                      protein features are of this type and some
                                      nucleic features (for example, CG-rich
                                      regions)).
       -strand             boolean    [N] Set this if you wish to display the
                                      strand of the features. Protein features are
                                      always directionless (indicated by '0'),
                                      forward is indicated by '+' and reverse is
                                      '-'.
       -source             boolean    [N] Set this if you wish to display the
                                      source of the features.
                                      The source name is usually either the name
                                      of the program that detected the feature or
                                      it is the name of the feature table (eg:
                                      EMBL) that the feature came from.
       -position           boolean    [N] Set this if you wish to display the
                                      start and end position of the features. If
                                      several features are being displayed on the
                                      same line, then the start and end positions
                                      will be joined by a comma, for example:
                                      '189-189,225-225'.
       -[no]type           boolean    [Y] Set this to be false if you do not wish
                                      to display the type of the features.
       -tags               boolean    [N] Set this to be false if you do not wish
                                      to display the tags and values of the
                                      features.
       -[no]values         boolean    [Y] Set this to be false if you do not wish
                                      to display the tag values of the features.
                                      If this is set to be false, only the tag
                                      names will be displayed. If the tags are not
                                      displayed, then the values will not be
                                      displayed. The value of the 'translation'
                                      tag is never displayed as it is often
                                      extremely long.
       -stricttags         boolean    [N] By default if any tag/value pair in a

Standard (Mandatory) qualifiers | Allowed values | Default
--- | --- | ---
[-sequence] (Parameter 1) | Sequence(s) filename and optional format, or reference (input USA) | Readable sequence(s) | Required
[-outfile] (Parameter 2) | Output file name | Output file | <*>.showfeat
Additional (Optional) qualifiers | Allowed values | Default
-matchsource | By default any feature source in the feature table is shown. You can set this to match any feature source you wish to show. The source name is usually either the name of the program that detected the feature or it is the feature table (eg: EMBL) that the feature came from. The source may be wildcarded by using '*'. If you wish to show more than one source, separate their names with the character '|', eg: gene* | embl | Any string is accepted | *
-matchtype | By default any feature type in the feature table is shown. You can set this to match any feature type you wish to show. See http://www3.ebi.ac.uk/Services/WebFeat/ for a list of the EMBL feature types and see Appendix A of the Swissprot user manual in http://www.expasy.ch/txt/userman.txt for a list of the Swissprot feature types. The type may be wildcarded by using '*'. If you wish to show more than one type, separate their names with the character '|', eg: *UTR | intron | Any string is accepted | *
-matchtag | Tags are the types of extra values that a feature may have. For example in the EMBL feature table, a 'CDS' type of feature may have the tags '/codon', '/codon_start', '/db_xref', '/EC_number', '/evidence', '/exception', '/function', '/gene', '/label', '/map', '/note', '/number', '/partial', '/product', '/protein_id', '/pseudo', '/standard_name', '/translation', '/transl_except', '/transl_table', or '/usedin'. Some of these tags also have values, for example '/gene' can have the value of the gene name. By default any feature tag in the feature table is shown. You can set this to match any feature tag you wish to show. The tag may be wildcarded by using '*'. If you wish to show more than one tag, separate their names with the character '|', eg: gene | label | Any string is accepted | *
-matchvalue | Tag values are the values associated with a feature tag. Tags are the types of extra values that a feature may have. For example in the EMBL feature table, a 'CDS' type of feature may have the tags '/codon', '/codon_start', '/db_xref', '/EC_number', '/evidence', '/exception', '/function', '/gene', '/label', '/map', '/note', '/number', '/partial', '/product', '/protein_id', '/pseudo', '/standard_name', '/translation', '/transl_except', '/transl_table', or '/usedin'. Only some of these tags can have values, for example '/gene' can have the value of the gene name. By default any feature tag value in the feature table is shown. You can set this to match any feature tag valueyou wish to show. The tag value may be wildcarded by using '*'. If you wish to show more than one tag value, separate their names with the character '|', eg: pax* | 10 | Any string is accepted | *
-sort | Sort features by Type, Start or Source, Nosort (don't sort - use input order) or join coding regions together and leave other features in the input order |
source | (Sort by Source)
start | (Sort by Start position)
type | (Sort by Type)
nosort | (No sorting done)
join | (Join coding regions together)
| start
-annotation | Regions to annotate by marking. If this is left blank, then no annotation is added. A set of regions is specified by a set of pairs of positions followed by optional text. The positions are integers. They are followed by any text (but not digits when on the command-line). Examples of region specifications are: 24-45 new domain 56-78 match to Mouse 1-100 First part 120-156 oligo A file of ranges to annotate (one range per line) can be specified as '@filename'. | Sequence range | If this is left blank, then no annotation is added.
Advanced (Unprompted) qualifiers | Allowed values | Default
-html | Use HTML formatting | Boolean value Yes/No | No
-[no]id | Set this to be false if you do not wish to display the ID name of the sequence. | Boolean value Yes/No | Yes
-[no]description | Set this to be false if you do not wish to display the description of the sequence. | Boolean value Yes/No | Yes
-[no]scale | Set this to be false if you do not wish to display the scale line. | Boolean value Yes/No | Yes
-width | You can expand (or contract) the width of the ASCII-character graphics display of the positions of the features using this value. For example, a width of 80 characters would cover a standard page width and a width a 10 characters would be nearly unreadable. If the width is set to less than 4, the graphics lines and the scale line will not be displayed. | Integer 0 or more | 60
-collapse | If this is set, then features from the same source and of the same type and sense are all printed on the same line. For instance if there are several features from the EMBL feature table (ie. the same source) which are all of type 'exon' in the same sense, then they will all be displayed on the same line. This makes it hard to distinguish overlapping features. If this is set to false then each feature is displayed on a separate line making it easier to distinguish where features start and end. | Boolean value Yes/No | No
-[no]forward | Set this to be false if you do not wish to display forward sense features. | Boolean value Yes/No | Yes
-[no]reverse | Set this to be false if you do not wish to display reverse sense features. | Boolean value Yes/No | Yes
-[no]unknown | Set this to be false if you do not wish to display unknown sense features. (ie. features with no directionality - all protein features are of this type and some nucleic features (for example, CG-rich regions)). | Boolean value Yes/No | Yes
-strand | Set this if you wish to display the strand of the features. Protein features are always directionless (indicated by '0'), forward is indicated by '+' and reverse is '-'. | Boolean value Yes/No | No
-source | Set this if you wish to display the source of the features. The source name is usually either the name of the program that detected the feature or it is the name of the feature table (eg: EMBL) that the feature came from. | Boolean value Yes/No | No
-position | Set this if you wish to display the start and end position of the features. If several features are being displayed on the same line, then the start and end positions will be joined by a comma, for example: '189-189,225-225'. | Boolean value Yes/No | No
-[no]type | Set this to be false if you do not wish to display the type of the features. | Boolean value Yes/No | Yes
-tags | Set this to be false if you do not wish to display the tags and values of the features. | Boolean value Yes/No | No
-[no]values | Set this to be false if you do not wish to display the tag values of the features. If this is set to be false, only the tag names will be displayed. If the tags are not displayed, then the values will not be displayed. The value of the 'translation' tag is never displayed as it is often extremely long. | Boolean value Yes/No | Yes
-stricttags | By default if any tag/value pair in a feature matches the specified tag and value, then all the tags/value pairs of that feature will be displayed. If this is set to be true, then only those tag/value pairs in a feature that match the specified tag and value will be displayed. | Boolean value Yes/No | No

## Data files

None.

## Notes

Sequence regions to annotate may be specified as a set or ranges. Optionally, forward and reverse sense features, and features of unspecified sense (for example, CG-rich regions), are displayed. Optionally, features from the same source and of the same type and sense may all be printed on the same line, although this may make it hard to distinguish overlapping features.

By default, any features in the feature table are displayed however there are options to restrict this by feature source, type, feature tag and feature tag value.

Features may be sorted by Type, Start or Source, left unsorted (in which case the same order as the input is used), or features for the coding regions presented all together.

Various options control what else is displayed, including the sequence ID, description, scale line, width of display, strand of the features, feature source, start and end positions, feature type, and feature tags and tag values. By default if any tag/value pair in a feature matches the specified tag and value, then all the tags/value pairs of that feature will be displayed. If this is set to be true, then only those tag/value pairs in a feature that match the specified tag and value will be displayed.

Optionally, output can be in HTML.
