Hello,

I'm having trouble with recon-all. For 1 of 49 subjects, it completes with the following error:

Other errors are found in the log which read:

 IFLAG= -1  LINE SEARCH FAILED. SEE DOCUMENTATION OF ROUTINE MCSRCH ERROR RETURN OF LINE SEARCH: INFO= 6 POSSIBLE CAUSES: FUNCTION OR GRADIENT ARE INCORRECT OR INCORRECT TOLERANCES

This subject's surf files are also empty.

I found this thread from two years ago mentioning a similar issue, but a solution was not available: http://www.mail-archive.com/freesurfer@nmr.mgh.harvard.edu/msg18863.html

Has there been any progress? I've attached my log file.

Any help is much appreciated!
