Re: [Freesurfer] recon-all error : Too many intersected faces for face 120047

Thank you for your reply.

Is it impossible with 2mm? Unfortunately, the data we collect for the study all have same thickness of voxel. And, there was a problem like the photo below, and only the recon-all.log could be attached to you.

Thanks, Jeongson ----------------------------------------------------------------------

Hi Jeongson

it certainly looks like something went badly wrong. 2mm may be too thick - we typically recommend <=1.5mm for any voxel direction. Can you send us the recon-all.log? And maybe a snapshot of the volume with the lh.orig.nofix and rh.orig.nofix overlaid?

cheers Bruce

Hello Freesurfer developers I'm starting using FS and I have a problem running recon-all. #recon-all -s /usr/local/freesurfer/subjects/20180108 -all I've attached the output to a ERROR image file.

We're doing on a GE scanner 3T, T1-FSPGR axial slices, 3D with a slice thickness of 2.0mm. freesurfer version : freesurfer-x86_64-unknown-linux-gnu-stable6-20170118

Any help is greatly appreciated.

Thanks.

Jeongson
