## Function

Display the trace in an ABI sequencer file

## Description

abiview reads in an ABI sequencer trace file and graphically displays the data. The probabilities of each of the 4 nucleotide bases along the sequencing run is plotted and the assigned nucleotide (`G`, `A`, `T`, `C` or `N`) from the ABI file is overlayed on the graphs. The complete sequence is written to an output file.

## Usage

Here is a sample session with abiview

    % abiview -graph cps
    Display the trace in an ABI sequencer file
    ABI sequencing trace file: abiview.abi

### Graphics File: abiview.ps

The horizontal scale of the output image labelled 'Residue Position' is only a very approximate indication of the spacing of residues in the image. The real residue spacing is variable, as it relies on the speed with which the oligo-nucleotides are eluted in the ABI sequencer. Do not be surprised to see the nucleotide signals spaced at a much greater distance than the horizontal scale might suggest.

## Data files

None.

## Notes

An ABI file (`*.abi`) contains sequence trace data and base calls from a run of an ABI nucleotide sequencer machine. A trace data file is what you get back from having some DNA sequenced, for example, by a 3730XL sequencer. The files are in "binary" format and so cannot be viewed directly on screen. To inspect the sequencing data you must use a trace viewer such as abiview. Another good trace viewer is FinchTV (http://www.geospiza.com/finchtv/). It is stand-alone program and is freely available.
