question re: ventromedial and dorsolateral frontal lobe volumes
by Bird, Anne 18 Sep '07

18 Sep '07

Will Freesurfer allow me to measure ventromedial and dorsolateral frontal lobe volumes? Thanks, Anne C. Bird, M.S.

multi-channel lesion segmentation.
by Mehul Sampat 18 Sep '07

18 Sep '07

Hi all, I would like to segment lesions using both T1 and FLAIR images. I think this is not possible with the current version of freesurfer. Is that right ? Could I somehow combine the segmentation results from aseg with the FLAIR images ? Regards Mehul

re-run FreeSurfer with v4
by Xiangchuan Chen 17 Sep '07

17 Sep '07

Hi all, I am working on 80 subjects' data with the following work flow: 1. -autorecon1 2. edit talairach registration 3. -autorecon1 4. -autorecon2 5. edit brainmask.mgz 6. edit wm.mgz 7. -autorecon2-wm 8. -autorecon3 I have already finished this work flow for 30 subjects with FreeSurfer v3.05. I have spent a lot of time on steps 2, 5 and 6. I am not worrying about the other steps because they are my computer's tasks, but not mine. So, if I re-run the same work flow with v4, do I have to go through all these steps? Any suggestions are greatly appreciated. Thanks in advance, Xiangchuan Chen

Re: Re: [Freesurfer] centos4_x86_64_V4.0 vs. centos4_V4.0

Hi Nick, Thank you for replying to my questions. I am glad to know why the centos4_x86_64_v4.0 version did not work on my laptop. For the tkmedit issue, the + and - icons next to the slice number entry box, and the arrow keys all work very well when I want to change the slice number one by one. But, I am not able to enter numbers into the slice number box. It may be inconvenient if I want to jump from slice #128 to slice #35.

centos4_x86_64_V4.0 vs. centos4_V4.0
by Xiangchuan Chen 17 Sep '07

17 Sep '07

Hi all, I had tried to play with FreeSurfer centos4_x86_64_v4.0 on my laptop in the past two days, and found that the tksurfer did not show the brain surface correctly. Today, I installed the centos4_v4.0 on the same laptop. This version seems to work well. The only difference I have noticed by far between these two versions is that the centos4_x86_64_v4.0 needs libglut.so.3, but the centos4_v4.0 does not. Can anybody tell me why this difference makes sense here? I also found that I could not input the slice # with keyboard in the TKMedit Tools window. Can anybody tell me how I can do that? My system: HP NC8430 laptop (ATI X1600 video card) Fedora 6 (X86_64) Thanks in advance, Xiangchuan Chen

thickness and curvature
by Don Hagler 17 Sep '07

17 Sep '07

I see that mris_make_surfaces is normally used to generate thickness and curvature. I would like to generate the ?h.thickness and ?h.curv files without running mris_make_surfaces (I already have white and pial surfaces). Can mris_thickness and mris_curvature (or other programs) give the same results? Those two programs are not heavily documented, so any help on which options to use (to give the same results as mris_make_surfaces) would be appreciated. _________________________________________________________________ Kick back and relax with hot games and cool activities at the Messenger Café. http://www.cafemessenger.com?ocid=TXT_TAGHM_SeptHMtagline1

Subgenual problems
by Alex Fornito 16 Sep '07

16 Sep '07

Hi all, I've been having problems getting accurate surfaces in the subgenual cingulate region, as illustrated in the attached pics. I previously posted to the list about this, and you sent me a newer mris_surf for an older version of freesurfer that fixed the problem in some, but not all cases. It seems like the new version (included with 4.0) is still giving me some grief. Any suggestions re: what I can do? Thanks for your help, Alex (I'm re-posting this query as per Bruce's request last week.)
