install in Debian/Ubuntu
by 申林 27 Jul '07

27 Jul '07

hi, I have download "freesurfer-Linux-rh9-stable-pub-v3.0.5-full.tar.gz" for Ubuntu and followed the "FreeSurfer Setup and Configuration" and "Testing your FreeSurfer installation". The first two steps( export and source ) were ok , however, tkmedit always did not work and retured "command is not found" as well as tksurfer . Is there difference between ubuntu and other linux version in installing freesurfer ? how to finish the installation in ubuntu or whether I should choose redhat ? thank you in advance !

mri_label2surf
by Alessandro Gagliardi 27 Jul '07

27 Jul '07

I've been doing all of my analysis with surface images and now I need to label my results. I can annotate the visualization in tksurfer but I can't see an automated way to, say, generate a list of all areas with voxels with a value over some threshold. I thought I might try going to the label files and using mri_label2vol followed by mri_vol2surf. I'm registering all my surfaces using the icosahedron target and outputting in analyze format so I can import it into R. I figured the best labels to use would be those from the fsaverage directory. I converted those into volume files, but in order to convert them into surfaces, I need a .reg file. I tried the sphere.regfiles in the surf subdirectory, but mri_vol2surf didn't like that. Using a .reg file for a volume registered to fsaverage seems redundant, but I see no way around it. Is there? Or am I doing this all wrong and there is a much better way to label my surfaces? Thanks, -- ,-------------------------------------------------- | Alessandro Gagliardi | Rutgers University Mind Brain Analysis | Integrative Neuroscience Program | alessandro(a)gagliardi.name `--------------------------------------------

aseg.stats detailed list
by Joan Fisher 27 Jul '07

27 Jul '07

Hello -- The aseg.stats output that I have itemizes the size of the structures up to line 86, but there are only zeros after that. For example, if I wanted to know the wm or ctx for the rh middle temporal gyrus, there's a line devoted to that, but no values. Is there an option that I should be using to get a complete listing of regional size? Many thanks, Joan Fisher U of C

OASIS freesurfer-processed dataset
by Satrajit Ghosh 27 Jul '07

27 Jul '07

Is there any documentation for the OASIS freesurfer-processed data? I'm looking for details of human intervention. For example, - were seeds inserted for any brains? - was the white matter edited - were cortical labels manually edited for correctness? Any documentation about the whole process would be much appreciated. Thanks, Satra

by Gallo, Antonio (NIH/NINDS) [F] 26 Jul '07

26 Jul '07

Hi All, Does anyone have any experience with FS installation under Fedora Core 7 Linux + ATI Mobility FireGL V5000 (256K) graphics card? Which is the correct version to use? Do I need any additional patches to download or are any other configuration settings necessary? Thanks in advance, Antonio Antonio Gallo, MD NIB-NINDS-NIH 10 Center Drive Building 10, Room 5B16 Bethesda, MD, 20892 - USA ph #: 001-301-402.6391 fax #: 001-301-402.0373 ***********************

freediffusion dtrecon mask
by Akram Bakkour 25 Jul '07

25 Jul '07

Hello, freesiffusion-support(a)nmr.mgh.harvard.edu doesn't seem to exist, so I'm hoping one of you can help me out. I seem to be having trouble with the -mask 0 flag in dtrecon. It doesn't apply a brainmask! I tried -mask 1 but that didn't work either. I unpacked the data properly, then ran diff-flirt -i f -o unwarp/f -tmpdir tmp for motion and eddy current correction and then ran dtrecon -i f -o maps -mask 0 but my maps/fa volume is not brain masked. Here are the logs: /space/thigpen/10/users/min/OFRR27/dti/025/unwarp/dtrecon-22259.log /space/thigpen/10/users/min/OFRR27/dti/025/unwarp/raw2tensor-22289.log /space/thigpen/10/users/min/OFRR27/dti/025/unwarp/tensor2eig-22447.log I can see where it says Calculating background fraction ... brain is 100% of volume nonbrain is 0% of volume but I still don't understand why it's not working. I even tried running dtrecon on the unpacked data without running diff-flirt, but no luck. Any and all help is highly appreciated. Thanks! Akram.

Partitioning GM/WM boundary surface
by Morgan Hough 25 Jul '07

25 Jul '07

I would like to obtain a ratio of gyral/sulcal GM/WM boundary surface area. I was wondering if the best solution would be to threshold each subject's ?h.sulc files to form a label that contains all gyral areas and then use mris_anatomical_stats -l to constrain a surface area measurement to this label? I was also wondering if there is a simple way to exclude the medial wall area from consideration in these calculations? Thanks in advance for your time. Cheers, -Morgan

Recon-all
by Sharon Ruso 25 Jul '07

25 Jul '07

Dear Freesurfers. I am facing a crucial point.:)and I need your help. After examining most of our subjects, we decided that there is no need to run all the procedures- work flow, since our data is not prone to too many failures, and just start with recon-all-all, get all the data and then start editing. Usually we have to add very few cp and to do some pial edits (not in all the cases).However, our talairach looks good, no skull striping problems and wm is also ok. I was wondering if running recon-all-all, and then fixing the i.e. cp , or the pial surface when repeating autorecon2-cp, or autorecon2-pial-autorecon3, is it harmful? Does this mass my analysis , or it's ok? Thank You Sharon

about mris_make_surfaces
by Ning Liu 24 Jul '07

24 Jul '07

Hi all, I am trying to use mris_make_surfaces to create the final surface. Is aseg.mgz necessary for running this command? If not, how can I let this command skip this file? Thanks.
