This is not due to a difference between T1 and T2 resolution. The problem is that the two T1 volumes (001.mgz and 002.mgz) are difference sizes. It is probably not a good idea to try to combine them, but if you really want to, I can supply you with a solution.

can you send the log file?

In the log file the error was:

  Currently not supported, maybe first make conform?
Debug info: size(1) = 1, 1, 1   size(0) = 0.7, 0.7, 0.8
MultiRegistration::loadMovables: voxel size is different /recons/subj1/mri/orig/002.mgz.

Subject: [Freesurfer] difference in T1 and T2 resolution
 
Dear Freesurfer experts,
I have T1 and T2 images were unfortunately acquired with different resolution (i.e the voxel sizes is not the same)
T1 is 280X280X208
T2 is 270X270X200

I tried to run "recon-all"  but it failed to process the data. The command that I used is :
pbsubmit -c " recon-all -subjid subj1 -T2  PATH_TO_/T2.nii.gz -qcache -T2pial -all" 
 
How can I analyze these images? Is it a correct procedure to conform the voxels using "mri_convert". Is this procedure correct? does it hurt the anatomy of the images?
 
I highly appreciate your help 
John
