The latest documentation on blast covers nothing about warnings yet old blast version of blast has a "-warning" option that enables you to suppress warnings. It's super infuriating that this isn't possible. I need it to not have warnings. How do?
Have you tried calling blast from python using subprocess.check_output?
Another option might be using blast from biopython package and following the response to Supress/silence warnings from BioPython
Have you tried redirecting stderr to /dev/null?
blastn [...] 2>/dev/null
Why do want to get rid of warnings at all costs?
