I have updated the binaries and set threads to 15. I will post an update once a subject is done.
After the update 3dQwarp -hview shows ++ OpenMP thread count = 15
This is the output for 3dinfo -extent for a couple of random subjects
-84.145836 90.854164 -116.968491 76.156509 -107.456924 91.293076
-71.374207 92.625793 -125.734436 88.953064 -113.288055 85.461945
Thanks a lot for the help.
Best,
S
