HI,
Apologies if this is more related to scripting than fsl directly.
I have a series of individual roi images (all from the same individual and in functional space) that I would like to merge together into a single image. I have tried scripting this using a for loop with fslmaths but (of course) only the last image in the list is saved;
e.g. for i in 1.nii.gz 2.nii.gz etc, do fslmaths base_image -add ${i};done
Any help appreciated
