Hello AFNI team,
I would like to create a left and right hemisphere atlas and add 1000 to the Right hemisphere.
atlas_L.nii.gz is the left hemisphere image.
atlas.nii.gz the entire atlas.
I first tried:
3dcalc -a atlas_L.nii.gz -b atlas.nii.gz -expr "(b-a)+(step(b-a)*1000)" -prefix atlas_R.nii.gz
and it didn't give me any logical result when:
3dcalc -a atlas_L.nii.gz -b atlas.nii.gz -expr "(b-a)+(step(b-a)*100)" -prefix atlas_R.nii.gz
did
I am not sure I understand what is going on =)
Have a good Weekend Y'all
