Hi Andy

I think the rh.white.H is generated by mris_curvature. Does that help?

Cheers,
Bruce

Hello,

We're seeing this error a lot: "Cannot find rh.white.H" which is generated here.

It does not occur if -parallel is turned off.

I see that reconbatchjobs does "exec" on the commands sequentially in the order of the list, but it runs each in the background: 

exec $JOB >> $LOG 2>&1 &

so I thought it might just be slightly possible that these two commands:

      set cmd1 = (rm -f $hemi.white.$suffix)

      set cmd2 = (ln -s $hemi.white.preaparc.$suffix $hemi.white.$suffix)

could end up in a race condition where the file is linked and then immediately removed if somehow the ln command is executed before the rm command.

However, I tried reproducing this behavior with a test script but the rm always happens before the ln.

Any help would be appreciated!

Thanks,
