Hi Alberto!
I tested it out and it works! Thank you so much!! I have a followup
question: what if the side of the CNTL is a custom input from the user?
I tried this but it only selects the CNTLs with upper case "M"
customSide= "M"
regex = re.compile(r"(.*[%s]_\w*_[cntlCNTL]{4})" %(customSide))
Thanks!
-Francesco
