Hi,

I want to convert a statistical array (F statistic) to p-values. I've chosen 3dPval to do this. The input file contains a single sub-brik of resolution:64 x 64 x 36 where each voxel is 4mm isotropic.This process is running on an Intel Xeon CPU E5-2640 2.4 Ghz.

So far the computation has been running for over 24 hours. I expected it to be much faster as the GUI can seemingly do this almost instantaneously.

Does anyone have any experience with this function that could tell me if this length of computation time is typical? Or suggest a faster alternative?

Kind regards,
Angus
