We are running an independent t-test on 77 vs 118 smoothed grey matter images for the purpose of running TCFE.
We're using a 64-bit system with 8 cores, 8Gb RAM and 2Gb of swap.
We keep getting the message:
Loading Data:
**********************************************************************************************************************************************
Data loaded
.......
Starting permutation 1 (Unpermuted data)
ERROR: Program failed, unknown exception
We have checked and re-checked all of the con and mat files and run them with and without a grp file and with and without a grey matter mask, but we cannot get the thing to work on more than 25 vs 25 images.
When we run "top" it seems to max out on both memory and swap file use.
Is there any way we can change the way this procedure operates in order to get it to work?
Any help would be appreciated.
