You haven't told us what you saved it as, but assuming whatever software you used can save in .nii.gz or .mgz simply save as that. Load the volume and change the colormap and opacity to your liking.

Hello:

I have a very simple question, after recon-all, I did some statistical analysis with some other softwares, so for example I got the p value for every voxel(volume_based),or p value for every vertex(surface-based), so I know how to map theses p values for surface-based pipeline, but for volume-based, how can we do that???

I know that in FMRI pipeline, we can use the significance map(sig.nii) as the overlay, but this is created by the group analysis(mri_glmfit), but can we created this sig.nii mannually and upload it to the oig.mgz and apar+aseg.mgz???

Really need your help.

Thanks in advance
