Hi - sorry for the delay - have been very busy with the FSL course this
week!
It's not completely clear exactly what it is you are wanting to do - if
you email exactly how you want to mask the filtered_func_data and also
send the command you tried, I may be able to say something more useful. In
terms of repeating it - avwmaths etc are deterministc programs - so their
output will not change over time...
Thanks :)
