so I turned off the batch (PBS) system and ran interactively and the permissions are ok which
indicates the batch system is doing something undesirable.
I have a few options
1. I have resurrected my old project permissions script for this new system (runs as root)
2. I'll see if I can find a PBS directive
3. I am wondering if I poke a chmod command in at the end of feat if that would do the
job. does the feat script always exit from the very last line (so I can put the chmod in there) ?
