samtools invalid option 'f'

[aflynncarroll]

When running MIDAS with "run_midas.py", I get the bellow error stating that 'f' is not a valid option for samtools. It looks like 'f' has been depreciated with samtools (http://www.htslib.org/doc/samtools-sort.html). Has anyone had this issue and is there an update?
