[Freesurfer] Hi Ubuntu- error on generate stats

Hi all, I am new to Freesurfer (and to linux) and appreciate if you could please help. Just managed to install FS onto Ubuntu 10.10 64 bit. I am going through buckner - tutorial for the group analysis with Qdec. I am at the step where I have to import the aseg and aparc data. I clicked on the "g

[Freesurfer] Hi and for clustering and tksurfer showing

Hi Freesurfer Experts, Thank you very much for your previous help! Thank you Nick so much for your really nice help! Everything is going on, now. The old problem has been resolved. However, the new problem was coming. I did a group analysis following the instruction in https://surfer.nmr.mgh.harvar

Re: [Freesurfer] Hi, a question on lgi

Dear Yuanchao, I believe that in the case of polymicrogyric cortex, the lGI will decrease because the total cortical surface (i.e. the above term of the lGI equation) is drastically decreased by the numerous and shallower sulci. However, I did not have any occasion to formally challenge

[Freesurfer] Hi, a question on lgi

Dear Mr or Ms, If a subject was identified with severe polymicrogyria, which is a brain malformation marked by development of numerous microgyri, what will the lgi of the subject behave? I want to know whether the lgi of the subject would increase or decrease compared with that of the brain of

Re: [Freesurfer] Hi, a problem!

Yes, you should. The lgi calculations make use of the curvature files, which are applicable only to cortex (although there is 'curvature' data for the corpus callosum region, by necessity of having a closed surface topology). There is a file called ?h.cortex.label which can be used to mask-off no

[Freesurfer] Hi, a problem!

Using lgi, I want to know whether I should mask out the corpus callosum and the structures which lies below the corpus callosum as I do it using thickness measure.    Thanks!   ___ 好玩贺卡等你发，邮箱贺卡全新上线！ http://card.mail.cn.yahoo.com/

Re: [Freesurfer] Hi and for transfer AFNI data to Free Surfer

Hi Xiaochu, I'm not sure how afni stores its ROIs, but I bet Ziad (ccd) can help. I'll leave the group statistics in a label for Nick and/or Doug mris_anatomical_stats -l ... will do it for an individual, so you can always run it that way, but I bet there is a better/easier way to do it. c

[Freesurfer] Hi and for transfer AFNI data to Free Surfer

Hi FreeSurfer experts, I am a beginner of free surfer. Now I am working on my previous dataset with new hypothesis. In this dataset, I found a ROI (located almost in gray matter) showed significant functional difference between groups. I want to test whether the cortical thickness is changed or not

Re: [Freesurfer] Hi,I met a problem!

can you be more explicit about what you did? Was it the pial surface from the same subject? Did you open tksurfer twice? Were there any error messages? Bruce On Wed, 31 Jan 2007, zhang yi wrote: Hi, After I open the lh inflated surface, I want to open another pial surface according to the f

[Freesurfer] Hi,I met a problem!

Hi, After I open the lh inflated surface, I want to open another pial surface according to the freesurfer tutorial. But, the computer showed that "core dumped" "alloc: invalid block 0xb65d20: 0 0 75" I tried many times, it showed the same above notes every time. So, I don't known what's wit

Re: [Freesurfer] Hi, question

Hi, if you have made the final surface, then the thickness measurements have already been done as well. They are stored in files named ?h.thickness in curvature file format (you can load and display them using the file->load curvature command in tksurfer). cheers, Bruce On Fri, 8 Oct 2004, Wan

[Freesurfer] Hi, question

After processing the volume, creating the surface, making the final surface and registering the surface, I would like to measure the cortical thickness with freesurfer. Could you please give me hints about how and where to start? thanks Wan Park ___ F
