Dear experts,

I am processing some data and one of my cases failed. I checked the recon-all.log and found the following:

#@# Talairach Failure Detection tis 11 dec 2018 11:32:31 CET

/home/daniel/FreeSurfer/0e63e2e7-d1e1-4e78-9106-150994a32c44/mri

talairach_afd -T 0.005 -xfm transforms/talairach.xfm

ERROR: talairach_afd: Talairach Transform: transforms/talairach.xfm ***FAILED*** (p=0.0000, pval=0.0000 < threshold=0.0050)

Manual Talairach alignment may be necessary, or

include the -notal-check flag to skip this test,

making sure the -notal-check flag follows -all

or -autorecon1 in the command string.

recon-all -s 0e63e2e7-d1e1-4e78-9106-150994a32c44 exited with ERRORS at tis 11 dec 2018 11:32:31 CET

Next, I tried to fix the issue by using tkregister:

tkregister2 --mgz --s tal_before --fstal

However, the Talairach volume does not load as a MOVEABLE volume.

When I check the available recon-all output I only have:

orig/001 --> looks good

rawavg --> looks good

orig --> its awful (it looks like millions of white tiny voxels on a black background)

nu --> it is empty

transforms/talairach.xfm --> is available

I was wondering if you would know about any way to fix this?

Thank you in advance,

Dani
