FreeSurfer Licence for Grid Computing?
by Henri Vrooman 19 Aug '09

19 Aug '09

Hi there, I have a question about FreeSurfer Licensing. For our image processing activities it would be very nice and helpful to install FreeSurfer on one of our National Grid Facilities. The Grid (BIGGRID) is sponsored by the Dutch Government and the European Community. The grid is solely used by researchers for scientific purposes. The Grid consists of about 2000 processing nodes, located at several dutch universities and hospitals. My question is: Is it possible to install FreeSurfer on these nodes with just 1 license? Or is there another procedure to achieve this. I don't know if this mailing list is the right way to ask. If not, maybe someone knows a contact person for me. Thanks for your help.

Question about "Getting started with your own data"
by 卯野賢太 19 Aug '09

19 Aug '09

Hi freesurfer gurus, We are trying to do reconstruction in tksurfer section according to the text. We have a question in "Getting started with your own data" section. In the text, the following commands are written, recon-all -s <subjid> \ -i <path_to_dicoms>/95555-2-1.dcm -i <path_to_dicoms>/95555-3-1.dcm In the above commands, 95555-2-1.dcm and 95555-3-1.dcm represent the data within the same session? Because the directories, path_to_dicoms, were the same, I thought so. However, 2 or 3 in each 95555-2-1.dcm and 95555-3-1 might represent the session number. We can't understand which is right. Please give me your suggestion. Thank you, Kenta

Hi, there, I am still facing the problem of "redraw failed: no gl window open", I got another linux machine with Nvidia graphic card, I ran the tksurfer command "tksurfer bert lh inflated", it still gave me the "redraw failed: no gl window open" error. surfer: current subjects dir: /home/m047599/freesurfer-install/freesurfer/subjects surfer: not in "scripts" dir ==> using cwd for session root surfer: session root data dir ($session) set to: surfer: /home/m047599 surfer: Reading header info from /home/m047599/freesurfer-install/freesurfer/subjects/bert/mri/T1.mgz surfer: vertices=131369, faces=262734 Loading /home/m047599/freesurfer-install/freesurfer/surface_labels.txt surfer: ### redraw failed: no gl window open surfer: double buffered window surfer: tkoInitWindow(bert) surfer: using interface /home/m047599/freesurfer-install/freesurfer/lib/tcl/tksurfer.tcl Reading /home/m047599/freesurfer-install/freesurfer/lib/tcl/tkm_common.tcl Reading /home/m047599/freesurfer-install/freesurfer/lib/tcl/tkm_wrappers.tcl Reading /home/m047599/freesurfer-install/freesurfer/lib/tcl/fsgdfPlot.tcl Reading /home/m047599/freesurfer-install/freesurfer/lib/tcl/tkUtils.tcl Successfully parsed tksurfer.tcl reading white matter vertex locations... I read a previously posted thread by Nick, it looks like we can download a new tksurfer.bin file to solve this problem at ftp://surfer.nmr.mgh.harvard.edu/transfer/outgoing/fsdev/nicks/stable/cento… I clicked the link, the file has been removed. Does any one can help me get the new link of this file? Thanks a lot!

WM intensity normalization problem
by Garth Coombs 18 Aug '09

18 Aug '09

Hi, I am running a patient of ours with some cortical degeneration through the recon process and have run across an interesting problem. It appears as if the intensity normalization process is missing a large portion of the cortex, resulting in an almost straight line through the middle of his head, with the center portion looking like the intensity normalization worked, but the cortex portion is very dark. The white matter in the cortex hasn't been normalized, and some of the gray matter looks as if it has been washed out or stripped away (that may just be due to the degeneration though). I have been going through and attempting to pick out control points to run -autorecon2-cp, but we wanted to check in and see if that was the best course of action for this particular subject before I got too far into it. The data can be found in /autofs/space/dinah_001/users/balaji/ SUBJECTS_DIR/subjects/ and the subject ID is amcg_anat Any advice would be greatly appreciated. Thanks! -Garth

ROI reliability
by jentis＠nmr.mgh.harvard.edu 18 Aug '09

18 Aug '09

Hi Freesurfer team, I am trying to get intra-rater reliability statistics on an ROI manually traced twice (blindly). The scans are anisotropic (.38 x .38 x .8 mm) and so I have not run them automatically through the Freesurfer segmentation because they fail after autorecon1. I tried to use the following command but have had problems: mris_anatomical_stats -a ${s}/label/${h}.aparc.annot -f cortical_thickness_stats/${h}_${s}.txt $s $h It seems this command requires certain data from the autorecon process such as wm.mgz and other surface information that I cannot get because autorecon fails on these types of scans. I have only traced one hemisphere (the Left) and the ROIs are saved as label files; an example is: /autofs/space/phrenic_007/users/jon/hires_amy/Round_2/HRDEV126/ whole_amygdala.label Is there another way to get reliability (pixel overlap, total number of pixels, etc.) for two ROIs? Would you suggest another command or is there a way to bypass those requirements for the mri_anatomical_stats command? Thanks!

generative group averages
by Dana W. Moore 17 Aug '09

Hi everyone, I am using aparcstatstable2 and asegstatstable2 to generate group information so I can get mean values for a group for certain regions. Is there a way to generate group results for right and left total thickness from mris_anatomical_stats? Thanks, Dana Dana W.

patch flattening and back
by oxro0＠yahoo.com 17 Aug '09

17 Aug '09

Hi, Does anyone know of a script that takes a surface patch, flattens it and then gives you the transformation matrix for each verrtex that allows you to put it back into the initial form? The purpose is to do 2D plane geometric operations on the flattened surface and then re-transform the output back onto the original surf configuration. I am working on it in Matlab, so Matlab code would be best. But it could also use FS surf files as input and output. Any suggestions are greatly appreciated! Best, Thomas
