Hi Flora,

Are all the inputs (including design and contrast files) valid? Also, consider simplifying the command line to a minimum, e.g,, drop -v and -T and see if the problem persists. It could give an indication of where the problem may lie.

Btw, with 200 subjects, there isn't much a need for variance smoothing (regardless, this shouldn't lead to an error).

If the problem persists and you'd like to send the file, please feel free to do so. I'll send instructions then.

All the best,

Anderson

Hello,

I am getting a rather opaque error when I try to run randomise and would appreciate any insight you can provide.

When I run the command:

randomise -i nopvcorr_all.nii.gz -o randomiseout -m /usr/local/fsl/data/standard/MNI152_T1_1mm_brain_mask.nii.gz -d ../design.mat -t ../design.con -T -v 5

There is a short wait before I get the following, very brief, command line output :

randomise options: -i nopvcorr_all.nii.gz -o randomiseout -m /usr/local/fsl/data/standard/MNI152_T1_1mm_brain_mask.nii.gz -d ../design.mat -t ../design.con -T -v 5

Loading Data: ERROR: Program failed, unknown exception

Exiting

Do you have any idea what may be the problem? Or is it possible to provide an input to find out any more information about what is going wrong? The input data I am providing is a 4D dataset containing 200 volumes (100 rest and 100 task). I had wondered if this may be too large a dataset to input to the command? Each volume of the data is a calibrated standard space perfusion image from oxford_asl analysis run on simulated ASL subtraction data.

Thanks for your help,

Flora Kennedy McConnell
