Drew,

The error "Can't open file" usually suggests that the file has moved or that you don't have permissions to access the file. 

Can you try:
hdr=spm_vol('/Data/PL005/visit_2/Functional_data/fcn_3/s6waPL005_fMRI_run3_SENSE_6_1.nii'); img=spm_read_vols(hdr);

to see if you can open the file.

I'm not sure about the other errors.

Best Regards, Donald McLaren

SPM,

I've run into a new error when using a script to create VOIs that has worked in the past. I'm aware of the usual 'no voxels survive' or 'empty region' errors but this is new. Any ideas as to what could be causing this? Please see below:
