Hello AFNI Experts,
I am working on a project that is linking MRS data with functional data.
I am trying to use the voxel that was aquired from the MRS data on each individual subject to be used as an ROI for the functional data.
In order to overlay the MRS voxel on top of each individual’s gray matter mask, the physicist resampled the gray matter mask from 192 X 192 X 144 to 256 X256 X256. However, to get the functional, T1, and ROI aligned, I will need to get the gray matter mask back into the same 192 X 192 X 144 matrix. I thought I could simply do this via 3dresample and have the T1 serve as the master. However, this went terribly awry. Is there perhaps a better way of going about this?
I would appreciate any guidance!
