How to flip L/R image in the freeview?
by Glen Lee 01 May '13

01 May '13

Freesurfer users, I'm a newbie for FS and have a rudimentary question for you. I have to overlay the group map for right hemisphere onto the lh.inflated (due to using sym space, where left surface map became symmetrical to the right), but I wonder if there is any way of reverting it back to rh.inflated after the overlay using the freeview software. Your help would be appreciated. -Glen

Visualize a fixed number of voxels using Tksurfer
by Martin Bleichner 01 May '13

01 May '13

Hi all, is there a way to visualize a fixed number of voxesl using TKsurfer. I want to display the 200 most active voxels (i.e. highest beta values) on the inflated surface. Is there a possibility within tksurfer or do I have to determine the corresponding threshold beforehand? Thanks Martin

Hi Doug, Thanks for your answer. I changed the last step as u suggested, but I think I need to clarify my question: Indeed values of the CC looks OK, but don't u think other values, like the ventricles are too high ? When I first run the script, I got all values and looked the the CC - it looked fine. Then, I wanted to validate with some other regions, just to show that I got the appropriate (low) FA values for regions I don't expect to see high values in - and things looked odd (too high). I remember Bruce also writing me that the values seems a little high, but we didn't further discuss. I read the following this link: http://surfer.nmr.mgh.harvard.edu/fswiki/FsTutorial/MultiModalDtiIndividual "The CC has an average FA of about 0.75, gyral parcellations are about 0.4, the left putamen is 0.27, and the ventricle is 0.2. This is as expected because the CC is highly directional with no crossing fibers so we would expect the CC to have the highest FA. The gyral white matter is also directional but has fibers crossing in them, so one expects the FA to be lower than CC. The gray matter (putamen) is still lower. The ventricle has no fibers, so we expect it to have the lowest FA". All my values are above 0.4.... Additionally, if in the last step I'm writing --seg /usr/local/freesurfer/subjects/Rotem_try/mri/wmparc.mgz why do I get 182 regions ? in my wmparc.stats I have only 70... I'm probably doing something wrong, but I can't really point to the problem, thus asking for your help. Attached is the table again, Thanks Rotem > The values look about right in the table.

Hi, I am facing the same error like Miklos Argyelan http://www.mail-archive.com/freesurfer@nmr.mgh.harvard.edu/msg28047.html and Jitesh Joshi http://www.mail-archive.com/freesurfer@nmr.mgh.harvard.edu/msg28071.html I am using freesurfer-Linux-centos6_x86_64-stable-pub-v5.2.0 with the updated version of the bbregister script. Thank you, Ioana

Dear FreeSurfers, I want to convert cortical labels to volumetric masks, the mask created are used to register with the normalized functional data and to define the roi, so could I run the following command? tkregister2 -mov sub/func.nii -noedit -s fsaverage -regheader -reg ./register.dat/ and the func.nii has been normalized (sub.nii) to the MNI space. And if the command is wrong, which command should I use? Best wishes, Meng
