I'm using Plastx (some faster equivalent of Blastx) to compare my 500k contigs to ncbi database in order to check some suspected unknown contamination. I would like to only select the results with a percentage of identity > 95%. However there is no such "percentage identity colum" in the output file.
I have some others info about HSP_identity, intensity and alignment. So I was wondering if it is possible to calcultate this percentage myself.
