These SGP predictions combine geneid predictions with tblastx comparison of the Human genome against the Chicken genome.
SGP was run on the masked fasta sequences for the following human genome version:

golden_path_200307 (hg16)

It was also using homology evidences (the SRs - similarity regions) from TBLASTX, in which a masked version of the previous human genome assembly was comparedagainst the following chicken assembly version:

golden_path_200402 (Feb. 2004)

Predictions were obtained per chromosome and output in the following formats:

chr1.sgp (geneid)

chr1.gff (geneid predictions in gff format)

chr1.gtf (geneid predictions in gtf format)

chr1.cds (nucleotide sequence of predicted sequences)

chr1.prot (amino acid sequence of predicted protein sequences)

chr1_tbxsr.gff (gff output of geneid combined with tblastx)
