qdec - design interaction
by Klara Mareckova 02 Apr '13

02 Apr '13

Hi, I'm new to freesurfer and I'm trying to use qdec to run a 2-way anova (sex, age, sex*age). How do I set up the design to get results for the interaction? Do I do that withing the qdec design tab? Or how else do I do it? (e.g. do I need to create a FSGD file? But where in qdec would I upload it?) Thanks a lot for your advice, Klara

RAS coordinates of adjacent vertices on surface
by Cesar Echavarria 02 Apr '13

02 Apr '13

Hi freesurfers, I'm looking at the flattened fsaverage surface and trying to figure out how to select a number of vertices that all lie on the same line. I would like to make this an automatic process so I'm trying to figure out how the RAS coordinates of these vertices relate to each other. I plan to then make a label file in which these vertices are listed. Please let me know if you have any insight into how this might be done. Thanks, Cesar Echavarria

Projection of markers from the scalp to cortical surfaces
by Eleonora Maggioni 02 Apr '13

02 Apr '13

Hi Freesurfer experts, I am new to FreeSurfer and I have a question. I have markers of EEG electrodes on the T1 image of a subject and I want to project them from the scalp to his pial surface (that I reconstructed using the standard procedure). To do so, I manually selected the central point of each marker in tkmedit and I defined a control point. Then I red that control point with tksurfer on the corresponding pial surface. This should be the projection to the pial surface: is this procedure correct? If yes, in which coordinate system is the projection made? Thank you in advance, Kind regards, -- Eleonora Maggioni BioEngineering PhD student Politecnico di Milano Istituto E.Medea, Bosisio Parini (LC)

Advertisement for a post-doc position
by Katell Mevel 02 Apr '13

02 Apr '13

Hi, I would be grateful if the following could be spread through the Freesurfer list. Thank you for your help, Best Katell Dear list, One post-doc position in multimodal brain imaging is available in our group, the deadline is 6th of May 2013. Please find the details below: *** Department Center of Neurodevelopmental Disorders at Karolinska Institutet (KIND)(www.ki.se/kind<http://www.ki.se/kind>) KIND is a competence center for research, development and education within the area of developmental psychopathology. The center is established in collaboration between Karolinska Institutet and Stockholm County Council, and aims at improving clinical practice, generating basic research, and spreading new knowledge to stakeholders. The Roots of Autism Twin Study Sweden (RATSS) is a research project within KIND, focusing on monozygotic twins being discordant for autism spectrum disorder and other neurodevelopmental disorders, e.g. ADHD. Twins are examined on multiple levels, among them functional and structural neuroimaging using MRI. Scanning is performed in the Karolinska Institutet MR Research Center, using a 3 Tesla MR scanner (GE MR750). The project is running since the late Summer 2011 and more than 40 pairs have been included. *** Duties As a post-doc, you will be mainly responsible for the acquisition and analyses of the multimodal neuroimaging data. This includes DTI, resting-state fMRI and structural T1, to be combined according to a brain connectome approach. This work will be done in close collaboration with the department of Clinical Neuroscience. The position also includes several other responsibilities, e.g. coordination of the neuroimaging works at KIND, involvement in international collaborations, administrative tasks, grant application and article writing. All the details about this position can be found here: https://ki.netrecruiter.se/what:job/jobID:18940/where:4/ Applications should be submitted here: https://ki.netrecruiter.se/en/what:login/jobID:18940/where:4/ Please note that we DO NOT ACCEPT applications being submitted by email. To be considered, your application must be submitted through the application system.

tracula bvecs
by stdp82＠virgilio.it 02 Apr '13

02 Apr '13

Hi Anastasia, my subjects have gradient=0 only in first or last line. I'm noting that the subjects having 0.000 0.000 0.000 in the first line of bvecs.txt (0 in vals.txt) show correct tracts. The subjects that having 0.000 0.000 0.000 as last line of bvecs.txt show wrong or lacking tracts. For these subjects, I have already checked registration and gradients. Is possible that this issue depends from setting of nb0. In both cases (first or last line with 0.000) I have used set nb0 = 1. Is this correct? Thank you very much, Stefano

qdec - 3 timepoints
by Harry Hallock [hhal5293＠uni.sydney.edu.au] 02 Apr '13

02 Apr '13

Hi, I'm currently doing a long analysis of a data set that contains two groups (training and control) and 3 timepoints (baseline -BL, follow up1- FU1 follow up2-FU2) I've put it through qdec. But for the analysis qdec only gives me one measure for long.thickness-avg, rate, pc1 and spc. How do i know which timepoints are being analyzed? i.e. is it simply FU2-BL? Or is it FU2-FU1 or FU1-BL? Is there a way i can test for each of these changes over time? Cheers, Harry

How to get surface-based AAL template
by ZhiLiangLong 01 Apr '13

01 Apr '13

Hi all; I need a suface-based aal template which is compatible with FS surface file. Is there a way i can get the surface-based aal template? I have an idea, that is to just transform the AAL template (.nii file) in MNI space onto the surface template (e.g. fsaverage template) in FS. Is it correct? if in this case, how can i do the transformation? Any suggestions appreciated. Besh wishes.
