I'm not sure what is happening or why the tal reg is apparently failing. My guess is that it is something non-standard about the image. The first thing to try is to run it at 1mm (without the -hires). At some point, you may have to send us the volume (or at least some pictures in axial, sag, and cor)

Hi FreeSurfer Developers,

I’m trying to run recon-all on a high resolution (0.65mm iso) MP2RAGE however I am receiving the following error.

talairach_avi --i orig_nu.mgz --xfm transforms/talairach.auto.xfm

talairach_avi log file is transforms/talairach_avi.log...

ERROR: mpr2mni305 failed, see transforms/talairach_avi.log

These are the options that I am using.

recon-all -all -s Freesurfer -i denoised_MP2RAGE.nii -T2 mean_denoised_MP2RAGE_T2W.nii -T2pial -multistrip -hires

Please let me know if you can help.
