Thank Doug for the response.
This is very interesting!! I never thought about that! I was thinking that the two images (i.e. T1 and T2) must have the same resolution.
I understand that when we talk about differnce in the size of the files that means either the thickness of the slices is different or the number of images is differnt correct?
Kindly could you please shed more light on this issue and how we can handle it.
Also is it matter if the resolution of the two images is different? How can I analyse such images correctly?
Many thanks!
John

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.

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 helpJohn_______________________________________________ Freesurfer mailing list Freesurfer@nmr.mgh.harvard.edu https://mail.nmr.mgh.harvard.edu/mailman/listinfo/freesurfer
