Hi, my functional runs are already coregistered and resliced to mri/orig.mgz (I use ROI from aseg+aparc and I want to avoid downsampling) so in theory I do not need to use bbregister to prepare registration file for mris_volsmooth. However, --reg argument in mris_volsmooth is mandatory. So far I was running bbregister on already coregistered files. Is there a clever way to skip this unnecessary step?
