temporal pole label
by kwa1＠rice.edu 25 May '11

25 May '11

Hello, I have a question about the labeling in tksurfer. My goal is to take an average inflated surface of 10 controls and then make a temporal pole label out of that average. Alternatively, if FS provides a label for the TP for each patient I could average the labels together. Do you have any idea how best to do this? Thanks in advance. Warm regards, Kareem

Error from cudadetect
by Howison, Mark 25 May '11

Dear Freesurfer developers, We have installed Freesurfer 5.0.0 (CentOS x86_64) on our compute cluster at Brown and are seeing the following error when running 'cudadetect': ERROR: cuda driver does not appear to be installed!

overlay properties tksurfer window incomplete...
by Gonzalo Rojas Costa 25 May '11

25 May '11

Hi: I have an ubuntu based computer with Freesurfer 5, and it seems that because the font size or the screen resolution, the lowest part of the "Overlay Properties" window in tksurfer didn't appears (Ok and Cancel buttons, for example, etc)... Any solution ?... Sincerely, Gonzalo Rojas Costa Laboratory for Advanced Medical Image Processing Department of Radiology Las Condes Clinic Lo Fontecilla 441, Las Condes, Santiago, Chile.

skull strip T2 image in Freesurfer
by Xiaoying Tang 24 May '11

24 May '11

Hi All, I am wondering whether there is any way to skull strip a T2 image using freesurfer. I tried to use the same way as for skullstripping T1 image, but always failed. I would be most grateful if someone can give me some suggestion. Best, Xiaoying Tang

Making a custom experimental template
by Joakim Vinberg 24 May '11

24 May '11

Hi FS crowd, I just want to make sure that I have the process correctly described for setting up a custom experimental template. I am basing this off of the SurfaceRegAndTemplates (http://surfer.nmr.mgh.harvard.edu/fswiki/SurfaceRegAndTemplates) and a hypothetical experiment with 10 subjects (s1, s2, ...s10). I apologize if this has been well-covered-I couldn't quite match it on the website or the archives. For the prep step, I believe my commands would be: mris_make_template lh sphere s1 custom_template_lh_0.tif mris_make_template rh sphere s1 custom_template_rh_0.tif which would result in two new template files names custom_template_lh_0.tif and custom_template_rh_0.tif For Round 1, I would first create another registration for each subject: mris_register s1/surf/lh.sphere custom_template_lh_0.tif s1/surf/lh.sphere.regcustom_0 mris_register s1/surf/rh.sphere custom_template_rh_0.tif s1/surf/rh.sphere.regcustom_0 ... mris_register s10/surf/lh.sphere custom_template_lh_0.tif s10/surf/lh.sphere.regcustom_0 mris_register s10/surf/rh.sphere custom_template_rh_0.tif s10/surf/rh.sphere.regcustom_0 And then create another custom template: mris_make_template lh sphere s1 s2 s3 ... s10 custom_template_lh_1.tif mris_make_template rh sphere s1 s2 s3 ... s10 custom_template_rh_1.tif For round 2, I would repeat Round 1, generating a new set of sphere.reg files, and then a new template, except substitute the custom template from round 1 (custom_template_lh_1.tif and custom_template_rh_1.tif). Then, I would register all of my data to the custom_template_lh_2.tif and custom_template_rh_2.tif generated at the end of round 2. From there, I am assuming that I could be able to use this new template as I would fsaverage. Am I correct, or have I missed a step? Thanks in advance for all of your help! Joakim

tksurfer' configure overlay window incomplete...

23 May '11

Hi: I have an ubuntu based computer with Freesurfer 5.0.0, and the lowest part of the View->Configure->Overlay window of tksurfer didn't appears (see attached image)... How can I correct it ?... The PC has 1440x900 of screen resolution... How can I view the complete window ?... In another PC with 1920x1080 of screen resolution, Freesurfer 4.5.0 and another Ubuntu version, that tksurfer window looks ok (see atached image)...

question abt fsaverage V1
by Ritobrato Datta 23 May '11

23 May '11

Hello All, I noticed that that there is a fsaverage/label/?h.V1.label Is this label created from the Hinds and Fischl method ? Can someone give some details abt it ? Also for individual subjects, when I run the V1 estimation using Hinds and Fischl method, how accurate are the V1 / V2 border compared to retinotopy ? Or which is more accurate ? Thanks Ri
