Re: [Freesurfer] XL defect in recon-all

Hi Devika

these types of huge defects usually mean something dramatic has gone wrong with e.g. the skull stripping. Even if it completes it is unlikely to generate accurate surfaces. Check the ?h.inflated.nofix and ?h.orig.nofix over the wm.mgz and you will likely find the issue quicky cheers Bruce On Fri, 31 Jan 2020, Devika K wrote:

Hi,

I am running recon-all on Freesurfer version 6. Few of my subject's have XL defect error as shown below. CORRECTING DEFECT 0 (vertices=18408, convex hull=3300, v0=0) XL defect detected...

This has been running for more than a day. How can I fix this error?  Please give me some commands to solve this issue.

Looking forward to hearing from you

Thanks and Regards Devika K
