Hi - yes you would need to get the values into a NIFTI file in order to run fslmaths - for example in matlab use the save_avw command.

The filtering of the FEAT model happens inside the feat_model C++ program, so unless you fool feat_model into thinking you're running FEAT this isn't a simple way to achieve this.

Cheers.

Thanks, a lot your answer.

I've a further problem, the regressor is in a text file, not in a *.nii file. So I think fslmaths won't handle it. But, as far as I know the temporal filter used for the images is used for the for the model as well, so somehow it should work, but in the log file, there is only the command for filter the 4D image.

Thanks,
Gabor
