### _Study.Name (Name)

(go to parent tag category listing)

NMR-STAR tag name | _Study.Name

Description

NMR-STAR name: _Study.Name
If this deposition combined with past entries or entries planned for the future will constitute a 'study' of a biopolymer, a name for the study can be entered in this field. The name should be brief but descriptive similar to the title of a paper or review article. A study is a collection of entries containing data for a set of related molecular systems (a series of single amino acid or nucleic acid variants) or for a single molecular system but published in more than one citation (i.e., chemical shifts in one publication, atomic coordinates in another, and an investigation of the polymer in complex with another polymer in a third). In rare cases, an entry may be a member of more than one study.
