Hi, I am trying to figure out how blastn calculates the values noted in the column qocvs
Here is my example:
qseqid sseqid sstart send pident qcovs qlen length mismatch gapopen gaps evalue bitscore
full refNZ_CP033688 352587 353830 100.000 100 2423 1244 0 0 0 0 2298
According to blastn qcovs is 100 but (length/qlen)*100 = 51%
Does anyone have an explanation for that calculation?
