Dear Freesurfer team,

I got the following error message after running recon-all -autorecon-pial -subjid sub-073_ses-BSL

I attach the recon-all.log file for inspection.

It seems the problem is with: IFLAG= -1  LINE SEARCH FAILED. SEE DOCUMENTATION OF ROUTINE MCSRCH ERROR RETURN OF LINE SEARCH: INFO= 3 POSSIBLE CAUSES: FUNCTION OR GRADIENT ARE INCORRECT OR INCORRECT TOLERANCESoutof QuasiNewtonEMA: 009: -log(p) =   -0.0  tol 0.000010

i was having troubles with the skull-stripping of this subject and what I did, and other times worked for me just fine, is run fsl_anat to skull-strip the image and then:

mri_convert T1_biascorr_brain.nii.gz brainmask.mgz

I replaced the problematic brainmask for this new one and ran the command above. It seems it has problems running it without troubles.

Before this, I tried watershed modifying it with different "h" and also gcut and nothing seemed to work improving the skull stripping.

I wonder if you could help me with this one subject.

Thank you in advance for all your help.

Kind regards,

Rosie
