Comments.Text: What more context should I give? I have the amino acid sequence of a protein and I want to find its genomic sequence in all available strains of a certain bacterium. I have tblastn hit results in .txt format. As I understand  after the accession number there is a colon and after it numbers signifying genomic position of hit sequence. In some cases, however, after the colon there is the letter 'c' and I have no clue what that means.
