the IFLAG messages can be ignored if mri_em_register is not exiting with error. which command is running that is exiting with error? can you send that command line from the recon-all.log file?

Hi,

Each time I have run recon-all on our subjects, I end up with the same slew of error messages underneath "Computing MAP estimate using [x number of] samples" and underneath "EM alignment process":

"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 TOLERANCES"

At the very end of the log file I see:

"Loading source label. Abort Linux rc-twice 2.6.39.2-mosix #1 SMP Wed Jun 29 11:53:08 EDT 2011 x86_64 x86_64 x86_64 GNU/Linux

recon-all -s 5 exited with ERRORS at Tue Sep 27 03:23:46 EDT 2011"

Any help on this would be greatly appreciated.

Best,

Warren
