External Email - Use Caution
Hello!
Thank you for the tip!
As i understand it, -lGI has only one input which is pial surface. I am running it without any other files in the subject directory, I only have Subject- Name_-Surf- ?h.pial files when I attempt to execute the -lGI on it. So theoretically I do not have any other files to compare vertices count or any other parameter with my input file.
Thank you for your time! Will appreciate any help. Yana

You can read them in nibabel and try it.
I doubt that lgi computation is supposed to work if the vertex counts don't match.

External Email - Use CautionDear Community,
I am new to the software, so please bare with my ignorance! I have a triangular meshes of both hemispheres that were created not in
FS
but in another mesh generating software. I converted them with nibabel
into
two .pial files. When I run a 'read' command on them, I see the same structure as I see on native .pial file: [image: image.png]
Previously I have already run a recon-all on the MRI data I have and generated lh/rh.pial files. I also run -localGI on them, and also got the results just fine. Every time I work on the same computer. THe meshes that I converted with nibabel look the same (except for transcription) as the one I got from MRI. I cannot distinguish them in Freeview. But when I try to get lGI I got the error message. The command I use : recon-all -s name -localGI THe error I got:
I will attached the log file for more information. FS version I am using: freesurfer-Linux-centos6_x86_64-stable-pub-v6.0.0-2beb96c
I will be very grateful for any tips what this error is about, as I
cannot
find any reference about it anywhere.
Thank you for you time! Yana _______________________________________________ Freesurfer mailing list Freesurfer@nmr.mgh.harvard.edu https://mail.nmr.mgh.harvard.edu/mailman/listinfo/freesurfer
