Re: [Freesurfer] Segmentatoin fault using Freesurfer Functions Fedora 19 - Freesurfer 5.1

Hi John we could give you a version with debugging info and source and you could run it in gdb and find out where it is crashing. Or you could send us the core fie from a version with debugging on cheers Bruce On Fri, 25 Apr 2014, West, John D. wrote: Hello. We are trying to get Frees

Re: [Freesurfer] Multi-echo FLASH

Hi Jon yes, that works fine. The mprage gives better CNR/unit time in the cortex, but if you are really only interested in MEG that is probably a secondary concern (it would be important if you were doing e.g. a thickness study) cheers Bruce On Fri, 25 Apr 2014, Jon Houck wrote: Hi all, I

Re: [Freesurfer] Catastrophic Surface Inaccuracies

Hi Jon in this kind of case the default method did the wrong thing (closing the hole instead of cutting the handle). You need to identify the incorrectly segmented voxels that cause the spurious correction and delete them from the wm.mgz, then run autorecon2-wm autorecon3 cheers Bruce On F

Thanks Bruce, I’ll check for such wm connections. Is this the default method for correcting topology issues? jon On Apr 25, 2014, at 10:59 PM, Bruce Fischl wrote: > Hi Jon > > that is almost certainly a topology correction problem. Check to see if the > wm.mgz contains any spurious connectio

Re: [Freesurfer] Catastrophic Surface Inaccuracies

Hi Jon that is almost certainly a topology correction problem. Check to see if the wm.mgz contains any spurious connections that cause the space that is missing in the ?h.white surface to be closed in a slice. If you upload the data we can show you how to correct it if you want. cheers Bruce

[Freesurfer] Multi-echo FLASH

Hi all, I'm building a scan protocol for what is primarily a MEG study, which needs T1 information for co-registration and T1/T2 information to construct an accurate BEM from the inner skull surface. It seems like the two multi-echo FLASH sequences at 5 and 30 degrees would give me all of the inf
