I would like to use the "SeedRad" option in InstaCorr in order to obtain correlations between a seed region to other brain regions. Does the "SeedRad" option in InstaCorr refer to the radius of the seed region in mm? Or does it refer to the number of voxels comprising the seed radius? I just want to be sure before I use this feature.
Additionally, is this seed radius refle

Thank you. I am having trouble finding the correct 3d warp dataset to use with the -nwarp option in 3dNwarpApply. I tried the following: 3dNwarpApply -nwarp anat.un.aff.qw_WARP.nii (from auto_warp.py), but the output's alignment is way off.
It's unclear to me where I can find the correct 3d warp transform to apply to my epi data. Is this dataset available in the auto_warp.py output?

I am attempting to nonlinearly transform T1 images and their previously aligned EPI datasets to MNI space. Should I use auto_warp.py on the T1 and EPI datasets individually, or should I use auto_warp.py on the T1 images and then use 3dNwarpApply on the EPI data with the -nwarp 'anat_un.aff.qw_WARP.nii' option? This is new for me, so thanks for your help.
