Hello!

I currently have a 255k assembled contigs transcriptome (de novo, Trinity) and I want to retrieve indentifiers and sequences in fasta format of the contigs that had hits in BLASTx (around 50%). There's any way to filter using the BLASTx output, an script and the transcriptome itself? O I should search an approach of parsing BLASTx output to contain sequences?.

Thanks in advance!
