Hi Thomas, > [...] spm_select does not append the frame information at the > end of the filenames (e.g. ',1' for 3D files, ',n' for 4D files). I found this too (with updates 826). Try the version of spm_select that I've put here: http://www.cs.ucl.ac.uk/staff/gridgway/vbm/spm_select.m with the additional 'ExtList' option. (you might want to save this as spm_select_mod.m or similar, or at least, back up your original.) I've also added FPList and ExtFPList options to add the full path, as has been complained about on the list before. It's not thoroughly tested, but: [files dirs] = spm_select('ExtList', direc, 'blah', 3:5) [files dirs] = spm_select('ExtFPList', direc, 'blah', 3:5) both do what I expect them to on an example directory. Let me know of any problems you find. Hopefully something similar to this version can make it into the official release... Best, Ged.
