Hello All, Is there any way in FreeSurfer to take the log transform of a .mgh file and save the output as .mgh file? Thank you. Minjie

Hi, I have a question running fsfast in my Mac, The mkcontrast command gave the error of can not launch matlab. Could you please let me know how to solve this problem.

intersection of triangles from the reconstructed pial surface
by mcpiastra＠libero.it 23 May '13

23 May '13

Dear Bruce, we have the same problem as Yasheng's so we would like to know how to solve it. To answer what you ask Yasheng: it intersects two faces, but what do you meant with "native (binary) format"? Thank you a lot. Best regards, Maria Carla e Gabriele Hi Yasheng, hmmm, there is triangle/triangle intersection code that is supposed to prevent this from happening. Does this happen if you use the native (binary) format? How many faces intersect?

But I got an error message from tetgen to say that some triangles are intersecting each other. I am not sure whether anyone has found this before. The file I tested was 004/lh.pial. I first transferred it to asc format with mris_convert, and then make a straightforward transfer to .off (used by tetgen and geomview). I loaded the .off file with geomview and it looks right. Then I run tetgen with the .off file and got an error message like below, which means that there are intersections among the facets. > Error: Invalid PLC. > Two subfaces (219028, 5283, 5282) and (219054, 5300, 5283) > are found intersecting each other. > Hint: Use -d switch to find all intersecting facets. > > This is a little strange to me since the topology issue has been handled in the reconstructed surface, does any one have any clue? > > Thank you very much! > > Yasheng > >

Hi Cathy, please cc the freesurfer list when replying, so that other people can profit from or contribute to the discussion. (Maybe someone else can comment on the transfer of edits in cross processing between versions 5.0.....5.3 ??) So your cross data is processed with a mix of version 5 and 5.1? or is all processed with 5.1? Within a study you should never mix versions, ie. process some subjects with one versions others with a different version. It is OK to mix some FS versions between the cross and long processing, if it is done for all subjects the same way. I think you have these options: 1. keep 5.1 cross sectional data (assuming all is 5.1) and run base and long with 5.3. Then start processing base and long (qual check the base and edit if necessary). It should also work if all cross data is in 5.0. 2. reprocess the cross sectionals with 5.3 keeping the edits. Check if edits got transferred correctly, maybe edit more (or remove edits). Then start the base and long (again qual check base and edit if necessary). Obviously 1. would be less work. If you have mixed versions in your cross data, I'd rather recommend 2.

temporal lobe left out in pial surface - edits on brainmask.mgz or brain.finalsurfs.mgz?
by Yizhou Ma 22 May '13

22 May '13

Dear FS experts, I have a subject where large portions of temporal lobe is not included in the pial surface. A member in my lab has suggested edits on brain.finalsurfs.mgz. However, in the following page it is indicated that edits on brain.finalsurfs.mgz is only intended for cases regarding inclusion of cerebellum. Can anyone please let me know which volume I should be working on in this case? http://ftp.nmr.mgh.harvard.edu/fswiki/FsTutorial/PialEdits Thanks, Cherry

Hi Cathy, I think the problem is when there are tabs AND spaces. Only spaces should also work. I can write some code (when I have time) that checks these things, maybe for the next release.

recon-all error
by Yizhou Ma 22 May '13

22 May '13

Dear FS experts, I have a recon-all error regarding one of my subjects. The scan suffers from weakened signals at the lower part of the brain. Skullstrip stripped most of the cerebellum at first, and we fixed it manually. After running recon-all for the first time, large portions of the temporal lobes were left out of the brain. Knowing that this may not be the correct way, we still tried to fixed that by adding lots of control points. The second run of recon-all, then, came back with the following error message:" Loading source data Reading curvature file /space/mdeh3/3/halgdev/projects/nyuproj/subjects/sub4422b/surf/rh.thickness ERROR: number of vertices in /space/mdeh3/3/halgdev/projects/nyuproj/subjects/sub4422b/surf/rh.thickness does not match surface (192226,134773) ERROR: reading curvature file Linux mmil-compute-1-11.local 2.6.18-308.16.1.el5 #1 SMP Tue Oct 2 22:01:43 EDT 2012 x86_64 x86_64 x86_64 GNU/Linux recon-all -s sub4422b exited with ERRORS at Mon May 20 " Any ideas for why it is, or how we can fix the problem at the temporal lobes, will be really appreciated.

FreeSurfer v5.3.0
by Kristina Nalbandian 21 May '13

21 May '13

Hello I am interested in downloading the FreeSurfer v5.3.0. I will be running it on a virtual machine platform in Windows (xubuntu). Are there any specific instructions for this on the FreeSurfer website because I noticed it runs on CentOS 6 x86_64 (64b). Or does the download come with the virtual machine? Thank you for your help, Kristina
