It's not clear from this though whether this is holding up your analysis - what program does "top" think is running? Cheers.

However in the log file it says: mkdir .files;cp /usr/share/fsl/4.1/doc/fsl.css .files;ln -s /usr/share/fsl/4.1/doc/images .files/images ln: creating symbolic link '*.files/images': operation not permitted Will this be a problem for my analyses? It is now running for 5 days and still did not do the registration (FNIRT; resampling 4mm). I am not sure if this could be normal or that maybe the upper error message is creating problem?
