Hi Aoife,
import os
for each_pbs in os.listdir("/home/user/pbs_files/"): # loop thru dir
if each_pbs[-4:].upper() == ".PBS": # check extension
os.system("MUSCLE " + each_pbs) # call CLI prog
I don't think you need to open or close the files if their names (As
opposed to their contents) are just going to be parameters to this
MUSCLE program.
If you want it to look in subfolders replace 'os.listdir' with 'os.walk'.
Hope this helps, if not please clarify :)
Cheers,
Roger.
