Re: [Freesurfer] Pial Surface Incorrect For Native T1

Another note, I just did a little experimenting, and it appears that using a RAS oriented image for the initial recon-all run (I've been using all LAS images) will fix the left-right flipping that occurs with mri_surf2surf. However the mesh is still oriented incorrectly, such that a-p is facing su

Hi Doug, Thanks for your continued help with this. I use freeview -v rawavg.mgz -f lh.pial.native The problem I was mentioning in my first message though, is that the native pial surface mesh output from mri_surf2surf is only oriented correctly in freeview, but not in any other mesh viewer (such

When I run your commands, the pial is correctly oriented and placed. What is your freeview command? This is what I use freeview -v rawavg.mgz --surface ../surf/lh.pial.native:edgecolor=yellow On 09/23/2014 06:11 PM, Zachary Greenberg wrote: > Hi Doug, > > Thanks for getting back to me and sorry

[Freesurfer] Pial Surface Incorrect For Native T1

Hello Freesurfer experts, I am having a tough time getting my pial surfaces into the correct anatomical space. I work with ECoG Patients, so we have pre-implant high resolution T1s (GE SPGR), and post-implant high resolution CTs that show the location of ECoG electrodes within the patient's skull.
