SGD_features.tab
The latest version of the SGD_features.tab file is based on Genome Version R64-2-1.
The SGD_features.tab file is updated weekly (Saturday).
NOTE: On 4 September 2004, the SGD_features.tab file replaced the previously
used chromosomal_feature.tab file.
File contents:
1. Information on current chromosomal features in SGD, including Dubious ORFs.
Also contains coordinates of intron, exons, and other subfeatures that are located
within a chromosomal feature.
2. The relationship between subfeatures and the feature in which they
are located is identified by the feature name in column #7 (parent
feature). For example, the parent feature of the intron found in
ACT1/YFL039C will be YFL039C. The parent feature of YFL039C is
chromosome 6.
3. The coordinates of all features are in chromosomal coordinates.
Columns within SGD_features.tab:
1. Primary SGDID (mandatory)
2. Feature type (mandatory)
3. Feature qualifier (optional)
4. Feature name (optional)
5. Standard gene name (optional)
6. Alias (optional, multiples separated by |)
7. Parent feature name (optional)
8. Secondary SGDID (optional, multiples separated by |)
9. Chromosome (optional)
10. Start_coordinate (optional)
11. Stop_coordinate (optional)
12. Strand (optional)
13. Genetic position (optional)
14. Coordinate version (optional)
15. Sequence version (optional)
16. Description (optional)
Note that "chromosome 17" is the mitochondrial chromosome.
The SGD_features.tab file is complemented by GFF3 file saccharomyces_cerevisiae.gff
