Hi Dhruman, I had this problem with a Debian (Etch) system with an ATI card, and the way I got it to work was to install the fglrx driver for the ATI card. I also was missing a bunch of OpenGL stuff, too, but I think the driver was the main issue. I'm unfamiliar with CentOS but these inst

i just fixed something like this on ubuntu 7.10 with an ati radeon x600.  the latest drivers run on aiglx which conflicts with the previous versions which run on xgl.  this sometimes even caused X to crash when running tksurfer and even glxgears. on my system this was resolved by simply remov

[Freesurfer] rawavg

When FreeSurfer performs the average of 2 or more scans to create rawavg.mgz, is the 001.mgz used as the target to which all other scans are moved /averaged to or is there some between-space alignment amongst the scans? -Joel ___ Freesurfer mailing list

001.mgz is used as the target. If you have other scanns in orig (eg, 002.mgz, 003.mg, etc), then those are aligned to 001.mgz, then all are averaged together. doug joel bruss wrote: When FreeSurfer performs the average of 2 or more scans to create rawavg.mgz, is the 001.mgz used as the

[Freesurfer] 2 Questions about Parcellation

2008-03-06 Thread Raymond Hill
Hello, We are beginning to explore the applicability of FreeSurfer for our research. Having done some initial runs, we have the following questions that I was hoping you might be able to address. 1.) For stats output, it seems there are two atlases for parcellation, resulting in ?h.aparc

thanks Ray: 1. There were two different parcellation schemes, by different neuroanatomists (one by Christophe Destrieux, and one by Rahul Desikan and Ron Killiany). 2. The unknown in the desikan/killiany atlas is medial wall and unfortunately much of the insula, which Ron is working on fixin

Re: [Freesurfer] optseq2 obscenely long null event

2008-03-06 Thread Doug Greve
It looks like you have an awful lot of null in there (6+7+8+6+7+8+11)*2 = 106 sec of stimulation The total run length is 130*2 = 260 sec Leaving 260-106 = 154 sec for null. There are only 7*2=14 events total, so the average null will be 154/14 = 11 sec I'm surprised that one null was 75 sec, but

It should not be happening. Does it happen everytime you make an edit and re-run with autorecon2-cp? Teddy Youn wrote: Hi all, another quick question. I don't know if anyone else has encountered this problem, but after making pial, wm and cp edits our group don't seem to retain all our edi
