Hi, In fact the reference to susan_smooth on the film_gls command line is not used, as susan is now called as a internal library call by film_gls - that's why you don't see a binary called susan_smooth (it's now called susan). So this doesn't explain the problem.... If it's still not clear from the logfiles what the problem is here, please feel free to upload the whole (unfinished) FEAT directory for us to take a quick look at. Please upload the files in a single compressed tarfile to http://www.fmrib.ox.ac.uk/cgi-bin/upload.cgi And then email me the upload ID. Cheers, Steve.
