Hi, I have been running subjects in Version 5, and notice there are consistently weird error messages in the skull strip section of recon-all.log. These look like:
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: 006: -log(p) = 10319.2 tol 0.000010
Despite the log containing a few of these warnings, recon-all itself almost always completes “without errors, ” and the subjects appear to be fully processed. However, I have noticed a greater prevalence of bad skull strips compared to version 4.5.
Does anyone know what this error means?
Thanks,
Brad Zoltick and Aaron Goldman
these messages can be ignored. they originate in the bowels of some fortran code of a minimization routine in a 3rd party library we use.
