I'm working with ion torrent data where I apply the program cutadapt. I'm analyzing ITS seq data, as well as Matk. When I'm using cutadapt, I search the information for this genes, and built new files accordingly to his information. For instance, when I search for ITS, I generate a file about this gene, and the same applies to the Matk gene. However, more recently I randomly picked a fasta sequence from ITS, blast it and received the information about the matk gene. Is this supposed to occur? Thank you for the help and so sorry for the naive question.
