In the mri output folder, I noticed that both the 0.33 mm and 1 mm (voxelspace) maps have subfields that do not overlap in space, meaning that each subfield occupies a unique location in space that does not overlap with other subfields (i.e., 12 subfields and 12 unique voxel intensities). I am wondering how this is achieved for both resolutions simultaneously. Do you 'fit' the subfields first to the 0.33 mm data and then transform the data to the 1mm space, or do you fit to both spaces separately? I would like to transform the subfields to 1.5 mm data and are able to do so accurately, but I run into problems with subfield overlap because of the down sampling. I am wondering how to best deal with this issue, and from seeing non-overlapping subfields at both 0.33 and 1 mm I am thinking there must be someway to deal with this issue.
