I played around with the script this morning and found that genskyvec
doesn't receive any input via the pipe on Windows XP. I googled around a
bit and it seems that this is a limitation of cmd.exe on Windows XP. Vista
and newer seem to work (just relying on Google here, did not test it
myself.) Some information can be found here:

As a work around you can specify the command as

gensky 3 21 12 | perl -S genskyvec.pl

This at least solves the problem of the empty pipe. It should work in a
Python Popen command, too.

Regards,
Thomas
