Dear freesurfer community,

we are conducting cortical-thickness analysis using freesurfer-5.1.0 and have been experiencing some problems with the automatic recognition of the control points.  For several subjects, we run the recon-all command and after about 40 hours of computations, we receive the error message “Excessive topologic defect encountered: could not allocate 171060256 edges for retessellation

Cannot allocate memory”.  After the occurrence of the error message, the computation is stopped.

Below, we provide the details of our setup and the exact error message for one subject.

Feel  free to ask for more information. Thank you very much for your help!

Yours sincerely,

Annemarie
