What is SeqCol?

Seqcol, or Sequence Collections, is a GA4GH-sponsored community effort to standardize unique identifiers for collections of sequences. Seqcol identifiers can be used to identify genomes, transcriptomes, or proteomes -- anything that can be represented as a collection of sequences. The seqcol protocol provides:

  1. implementations of an algorithm for computing sequence identifiers;
  2. a lookup service to retrieve sequences given a seqcol identifier
  3. programmatic approach to assessing compatibility among sequence collections.
