Hi Ajay,

Yes, the centos_7 package is compiled with OpenMP support.


What is the RAM comparison between those systems? There is a
reasonable chance that the RedHat system ran out of memory.

It is also worth noting that there was a small bug in the handling of
warp file names, however that seems very unlikely to be relevant.
But see this thread.

In any case, it might be worth trying that exact command with the
centos_7 binaries. To do so, go to the results directory and:

wget [afni.nimh.nih.gov]
chmod 755 3dNwarpApply
./3dNwarpApply -interp NN -nwarp ...

The 3dNwarpApply command should be the exact same one you
ran before, but with ./3dNwarpApply, to use the one in the current
directory.

Does that work any better? Probably not, but it is worth trying.
Also, try to monitor memory use while it runs, if possible.
