t-statistics map using tksurfer
by Chung, Yoonho 15 Sep '13

15 Sep '13

Dear all, Is there a way to visualize vertex wise t-values (t-statistics), instead of p-values, on a vertex map when you are doing group analyses? I successfully generated the p-maps using mri_glfmfit, but I am wondering if vertex-wise maps that represent t-values can be also generated and visualized using tksurfer. Another question I have is that is there a way to generate just average thickness maps within the same group? For example, if want to look at a vertex map that just shows mean thickness of all my controls, how would you generate that file that can be fed into tksurfer? Thanks in advance! Yoon

mapping extracted MNI152 ROIs to individual subjects
by Paul Beach 13 Sep '13

13 Sep '13

Hello Freesurfer experts, I am currently trying to take extracted cortical networks from the Yeo_JNeurophysiol11_MNI152 package<https://surfer.nmr.mgh.harvard.edu/fswiki/CorticalParcellation_Yeo2011>and translate them to individual subjects to perform functional connectivity analyses - based on the individual networks, themselves. Currently the extracted ROIs are in '.nii.gz' format. My question is: How do I take the extracted ROIs and map them on to individual subjects? My thought was that mri_vol2vol could perhaps accomplish this, but I cannot find a help file for this command that would guide me in developing the line of code to write. Thanks! -- Paul Beach DO/PhD candidate - Year VI Michigan State University - College of Osteopathic Medicine - Neuroscience Program - Bozoki Lab: Neurology/Radiology

Tracula and Qdec
by Alan Francis 13 Sep '13

13 Sep '13

Hi Anastasia and FreeSurfers: Is it possible to model Tracula data on Qdec? I have some interesting findings in FA and AD between two groups that I am hoping to visually represent on a single brain. Any advice would be deeply appreciated. thank you, Alan

crash during longitudinal process when it run mri_ca_register
by Knut J Bjuland 13 Sep '13

13 Sep '13

Hi, I have run recon-al longitudinal process on abel cluster with this command recon-all -base @filename@_template -tp @filename@ -tp @filename@v2 -all -debug. However, it crashed or is killed when it ran mri_ca_register. I have looked through the log, and I have not found a reason for it being killed even tough I added -debug. The cluster is running sbatch and CentOS release 6.4. Are there any debug options I can add or are there any debugversion of mri_ca_register I can download? This happen every time I run the program. I have asked for 8g ram when ran the program. Best regards Knut Jørgen Bjuland

Re: [Freesurfer] license error with FS5.3
by S.V.Shepherd [work] 13 Sep '13

13 Sep '13

Solved: The license file actually differed from the other installations in that the "#----cut here-----" lines were included. To my embarrassment, it took a second pair of eyes to notice this. I thought I'd fess up lest anyone else make the same mistake. stephen

Re: [Freesurfer] recon all question
by Rashmi Singh 13 Sep '13

Hey Bruce, I have two more questions. 1) I was suggested to use mri_binarize with brain.mgz to get the total brain volume. Is there any reference that I can cite regarding use of mri_binarize to calculate total brain volume. 2)I learnt that using T2 weighted image along with T1 weighted image from the same scanning session generates a good contrast and gives better segmentation/parcellation outputs using FreeSurfer. May the FreeSurfer experts guide me through this.

recon all question
by Rashmi Singh 12 Sep '13

12 Sep '13

Hello Freesurfer experts, I am doing volumetrics study. During the scan we get 2-3 mprage per scan for a subject. While running the FreeSurfer, if I want to use the three mprages for that subject as an input file, may I just keep the three mgz files (001.mgz, 002 .mgz and 003.mgz) in the orig folder and run the simple recon all command :=Recon-all -s (subject file name) -all or do I need to have some additional l flags so that recon all command will use the three T1 images to get one output file? Thanks, Rashmi

old colin27
by Rouhollah Abdollahi 12 Sep '13

12 Sep '13

Dear freesurfer I am looking for old segmentation of Colin27 that you have replaced with new version. Is there anywhere that I can find archive of colin27 segmentations. I think it might be segmented with freesurfer 3 or 4. Because I have some labels from the old version. But I dont have the segmentation files and all surfaces. I think I need all surfaces to be able to use label2label command. one surface that I have, shows the lh.pial has 170783 vertices and it could be created in 2010 or before. Could you help me about that? -- Best Regards Rouhollah Abdollahi
