Magic-BLAST does not use read quality scores, because they are not always accurate. The scores are not included in the SAM report.
@yech1990, are quality scores needed in downstream analysis?
Hi @boratyng
Yes. I know BLAST do not use quality score during the mapping step. But to make them output sam file compatible with other NGS tools, I think Magic-BLAST can append the quality score back into the sam file after the mapping.
Yes, we can do this, will try for the next release.
Hi @y9c, Magic-BLAST 1.7.0 which was recently released reports read quality scores in the SAM output. Here are installation instructions: https://ncbi.github.io/magicblast/doc/download.html.
Seem that read quality field is missing in the sam output file.
