Hi Doug,

Our freeview command is: freeview -v ${fs_id}/mri/T1.mgz ${fs_id}/mri/brainmask.mgz:colormap=heat:opacity=0.4

Thank you,

Kaley

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.

In the log file the error was:

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
