The output dataset is saved as dsetprefix_extract+orig. It's set in the line where it says

set outdset = ${dset}_extract

There are no spaces after the '$'. On my browser, it looks like an extra space, but there aren't any. This is hard-coded in the script, but is easily modified to use user input if you like. So if you call this script with

tcsh extract_time.csh 10 mydset+orig

The output dataset should be in the directory as mydset_extract+orig.HEAD and .BRIK.
