Thanks Bob.

I ended up using (cd a; 3dTstat -stdev -prefix output.1D input.1D\' ) but your suggestion is cleaner.

The reason I assumed -prefix a/b/c worked with 3dTstat was that -prefix a/b/c seems to work as expected in 3dcalc.

Could I make one more suggestion about the documentation of 3drefit?
I suggesting changing

20 Jun 2006: 3drefit will now work on NIfTI datasets (but it will
write out the entire dataset)

to
20 Jun 2006: 3drefit will now work on NIfTI datasets (but it will
write out the entire dataset in the current working directory)

I've been bitten by

3drefit -deoblique a/b/c.nii.gz

writing $cwd/c.nii.gz and leaving a/b/c.nii.gz intact
