OASIS Freesurfer Data
by Daniel Marcus 27 Jun '07

27 Jun '07

Hi folks- The Freesurfer processing of the OASIS cross-sectional data set is now available for download via anonymous FTP. The whole set will also be available at the OASIS website in the coming weeks. Check out www.oasis-brains.org for more information on the OASIS project. Download instructions: -ftp to www.oasis-brains.org -login as anonymous (use email address as password) -cd to data -mget oasis_cs_freesurfer* The full set is ~150 GB. It is divided into 11 separate .tar.gz files. This data set falls under the same Data Usage Agreement as the core OASIS data (http://www.oasis-brains.org/app/template/UsageAgreement.vm) Most importantly, please make sure to properly acknowledge its origin. Again, thanks to Bruce, Jenni, and the rest of the folks at MGH for generating this very cool data set and for making it widely available.

Making labels from the commandline
by Morgan Hough 27 Jun '07

27 Jun '07

I was wondering if I can make a cortical label from a volume ROI from the commandline. I would like to extract thickness values from a region defined in each subject's volume space. Thanks in advance. Cheers, -Morgan

hi ,I have solved the the probelm.Now, I have some new question, just as belows:1  In the GUI interface, I can't type the letters ,I don't know why?2 when I choose the volume in the Morphometric-----Measure, the Qdec runs error. how to solve it ? the screenshot on the attachment.3 In the terminal command window, I type the make_average_subject command,It runs errors , show as :limit:decriptors:can't remove limite(operation not permition), how to deal with this bug?Thank you very much!!!

anat2exf.register.dat missing
by Furlong, Carolyn 27 Jun '07

27 Jun '07

Hi We have run the command reg-feat2anat --debug --feat /disc2/Kate/Data_FSL/Pre_AM/AM_prelip_BET.feat --subject AMoore which generates several files with matricies in them but the file anat2exf.register.dat is missing. The output is below... tkregister2 popped up, the original surface green outline is not visible and there is a shift (3cm) with respect to the anatomical, I was wondering if the command ran successfully?

group analysis using mri_glmfit
by T. Song 26 Jun '07

26 Jun '07

Hi Bruce and Nick: I am trying to do group analysis using mri_glmfit. It seems that I have no problem to run mri_glmfit and get the glmdir and all the files. When I load sig.mgh with average surface in tksurfer, I can configure the overlay. When I try to load group descriptor file, a window pop up with the title I defined in the fsgd file. Now, if I click a point in the tksurfer window, tksurfer will crash. I examine the command line, it seems that after the group descriptor file is loaded, tksurfer can not get the vertex number. I tried this on 32 bit machine and 64 bit machine, same result? Would you please give me some suggestion? Thanks! Tao

metric distortion questions
by Morgan Hough 26 Jun '07

26 Jun '07

Hi there, I would like to ask some questions about metric distortion. 1. Following the Wisco et al (2007) paper, metric distortion is defined as Metric Distortion = k * area of a triangle on a registered sphere / area of triangle on gray/white interface surface which I believe I can compute using mris_jacobian $subject/surf/lh.sphere $subject/surf/lh.sphere.reg $subject/surf/lh.sphere.reg.jacobian The subject 's ?h.sphere.reg is formed from the registration of the inflated sphere of the subject with the Desikan et al. (2006) 40 subject template? From the wiki, I think the command is mris_register -curv ?h.sphere $FREESURFER_HOME/average/?h.average.curvature.filled.buckner40.tif ?h.sphere.reg so the jacobian measure is derived from the parcellation stage (stage3) of recon-all. 2. I would like to extract the k factor for each subject which is defined as k = total surface area of original gray/white interface surface / total surface area of individual sphere do I compute this from the total surface area field of mris_anatomical_stats $subject $hemi orig / mris_anatomical_stats $subject $hemi sphere or do I need to use outputs from different surfaces or extract either value differently? The sphere values look rather uniform and I wanted to check if I am using the right thing. 3. Finally, I see in the study average make_average_surface.log file: setting group surface area to be 1142.0 cm^2 (scale=1.29) and I was wondering what the scale factor represented here. Thanks in advance for your time. Cheers, -Morgan

linear opaque threshold
by Robert Levy 26 Jun '07

26 Jun '07

Hello, Does anyone know if it is possible to set the overlay threshold to "linear opaque" mode in tksurfer using TCL commands? I looked at the documentation, and I didn't see a method explicitly for that purpose, but maybe there is some way to specify that option. Thanks, Rob
