Flat file features

The following documents describe in detail the features of various flat files:

Index files

The index keys (accession numbers, keywords, authors, journals, and gene symbols.) of an index are sorted alphabetically. Following each index key, the identifiers of the sequence entries containing that key are listed (LOCUS name, division abbreviation, and primary accession number). The division abbreviations are:

PRI - primate sequences
ROD - rodent sequences
MAM - other mammalian sequences
VRT - other vertebrate sequences
INV - invertebrate sequences
PLN - plant, fungal, and algal sequences
BCT - bacterial sequences
VRL - viral sequences
PHG - bacteriophage sequences
SYN - synthetic sequences
UNA - unannotated sequences
EST - EST sequences (expressed sequence tags)
PAT - patent sequences
STS - STS sequences (sequence tagged sites)
GSS - GSS sequences (genome survey sequences)
HTG - HTGS sequences (high throughput genomic sequences)
HTC - HTC sequences (high throughput cDNA sequences)
ENV - Environmental sampling sequences
CON - Constructed sequences
WGS - Whole Genome Shotgun sequencing projects
