Thank you very much! I will give that a try.
In addition to using 3dsample, I noticed that the orientation of my stats file and my VBM images may be different, though, I am not too sure (one is right to left, and the other is left to right). Do I need to flip my VBM to match my stats file?
Thank you again.
My VBM files:
Data Axes Orientation:
first (x) = Right-to-Left
second (y) = P

They do not (see 3dinfo below).
Do you suggest I alter the VBM input so that it aligns with a 2x2x2 voxel size to match my fmri outputs?
Essentially, I ran VBM using SPM and I would like to enter the grey matter maps as a covariate in my analysis to account for differences in atrophy in my groups. During one of the VBM steps (align to an MNI template), I specified the voxel size of the MNI

Hi Gang,
I completed VBM using SPM and indicates the specific voxel size, bounding box to match the the MNI template I used for registration (SSwarper). I indicated the smoothing to match what I used in my AFNI pre-processing script. Should I have indicated the voxel size to match my fmri data instead
Thank you,
Tamara

Hello,
I am attempting to include a voxel-wise covariate (a nifti file showing the grey matter probability maps from VBM analysis) in my 3dMVM script see below, but I keep getting this error and I am not sure what this pertains to. Any help or suggestions is much appreciated!
Error in dim(vQV) <- c(dimx, dimy, dimz, length(unique(lop$dataStr[, lop$vQV[1]]))) :
