It's a cluster running Linux CentOS 64-bit. If it's as simple as getting the file and adding it to my path I'm happy to give it a try... Chris On Thu, Dec 10, 2015 at 1:47 PM, Bruce Fischl wrote: > what hardware are you running on? We can send you a version of > mris_copy_header. Or you can can

what hardware are you running on? We can send you a version of mris_copy_header. Or you can can send me the two surfaces (before and after smoothing) and I can see if it fixes the problem cheers Bruce On Thu, 10 Dec 2015, Chris Holdgraf wrote: Yep - sorry, here's apic:  https://cloud.github

and how do you determine they are shifted? In freeview? The surface geometry/position should be preserved in the smoothing but appears to not to be. Perhaps Marie can comment? Or you can try mris_copy_header to see if that does the trick cheers Bruce On Thu, 10 Dec 2015, Chris Holdgraf wrot

Hey Bruce - thus far I have used pretty default parameters. I first ran recon-all on each subject, then simply ran `recon-all -s s_name -localGI`. Here are the transforms for the original vs. inflated surface On lh.pial: talairch.xfm: 1.103 0.015 -0.002 4.202; -0.032 1.064 0.063 -19.65

Hi Chris how do you smooth the surface? Are you sure that you retain the surface header information? Try looking at the header with mris_info before and after smoothing cheers Bruce On Thu, 10 Dec 2015, Chris Holdgraf wrote: > Hey Freesurfer folks - I'm looking into using Freesurfer for doing

Hey Freesurfer folks - I'm looking into using Freesurfer for doing electrode reconstruction / co-registration in electrocorticography. We're making good progress on figuring out recon-all for surfaces and doing co-registration to CTs. However, I think I've encountered a strange bug. I'm trying to
