Hello dear Freesurfer developers, nice to e-meet you and thank you for working on this open source software!

I am trying to produce a 3D file of a brain.

The command I am trying to run is recon-all and here is the error I get:

CORRECTING DEFECT 57 (vertices=33394, convex hull=9966)
Excessive topologic defect encountered: could not allocate 140742253
edges for retessellation
Cannot allocate memory

The version I am using is: freesurfer-Linux-centos4-stable-pub-v5.3.0

The platform is Red Hat 64-bit running in a Virtual box with 7835mb allocated memory.

You will find the corresponding log file attached.

Isn't it surprising that I don't have enough memory with 7835mb allocated? Sorry, I am new to Freesurfer and there might be something I didn't get.

Thank you very much in advance for your help,

Regards,
