Alfonso,

Thanks so much for getting back to me. I checked the functional normalization plots, like you suggested, and I do see the problem there (see attached screenshots for the same two subjects I shared photos of in my first message). What do you recommend as the best way to fix this??

As a reminder, we used the preprocessing pipeline for volume-based analyses (indirect normalization to MNI-space) when FieldMaps are available, and our field maps were calculated from two separate acquisitions with opposite phase encoding directions.

Thanks again for your help!
