silkworm_PublicKnow_TE.gff is the result of masking silkworm genome with Public known TE. All on one line, for example here (with descriptions): ------ nscaf100 RepeatMasker TE 1 172 1400 - . TransposonPrediction BGIBMKNOWNTEA00000001 Target "Bmmar1.B12" 546 368 class "DNA-BM" ------ Where: nscaf100: is the id of the genome sequence. RepeatMasker: is the method TE: is the kind of sequence. 1: is the start of the gene. 172: is the end of the gene. 1400: is the score of prediction. -: is the strand of gene. BGIBMKNOWNTEA00000001: is the id of the TE. Target "Bmmar1.B12" 546 368 class "DNA-BM": is the homology annotation.
