This might be a silly question, but are you sure you're using the correct filename? I believe "grot" is basically the UK English version of "foo". Does that file exist on your system?

[log in to unmask]" type="cite"> Hi Steve, Thank you for your reply. I tried running fslstats command as you recommended but unfortunately, all I got was just zero. Nothing but zero. This is so weird because, when I run "fslstats -t grot -R -V", the result shows as follows: 0.000000 3.981812 24 24.000000, which means the grot file itself has some data. Could I please hear of any advice to resolve this issue?
