Sorry, here is the exact error: Traceback (most recent call last): File "hapSim.py", line 415, in ? run(REPLICATES, dsSelection, permuteStatus, sigThreshold File "hapSim.py", line 354, in run createInput(dt) File "hapSim.py", line 178, in createInput inF = open(IN_FNAME, "w") IOError: [Errno 2] No such file or directory: 'prog.input' I am using the same file name repeatedly, it works fine the first few thousand times, but eventually gives this error. -- http://mail.python.org/mailman/listinfo/python-list
