The -float option forces the output to float which is useful if you have multiple sub-brick scale factors for 16-bit short integer data.
Also most AFNI programs can read and write NIFTI themselves, so 3dcopy can do this with
3dcopy dset+orig dset.nii
Other programs create NIFTI output if the dataset prefix is specified with the .nii suffix. For example,
3dcalc -a dset+orig -prefix dset.nii -expr 'a'

Several questions:
1) Does fsl_installer.sh overwrite whatever was in .profile, or does it just add to .profile?
(I ask because after I used ./fsl_installer.sh to do a general install on a mac tiger machine,
our path to the afni bin was lost and had to be put back in-thing is, I didn't set up the afni path
in the first place, so I'm not sure what may have happened.)
2) Is there a simple way to convert BRIK/HEAD pairs into nifti.gz files to view them in fsl?
3) Is there any difference between the results of the following 2 procedures:
a) Run probtrack with a termination mask
OR
b) Run probtrack without the termination mask, but then use the mask to subtract any part of the tract
that overlaps the mask.
Thankyou so much,
-Dianne
