I'm surprised that base.txt is generated at all, I'd expect fix.pl to look
for a file named "base.gtx >base.txt" and complain when it doesn't find
that.
I think the following should work:
with open("c:/scripts/perl/base.txt", "w") as f:
subprocess.check_call(
["perl",
"c:/scripts/perl/fix.pl",
"c:/scripts/perl/base.gtx"],
stdout=f)
