right choroid plexus missing
by Mishkin Derakhshan 14 Dec '07

14 Dec '07

Hi, Is there any reason why aseg.stats only has a label for the left-choroid-plexus (id 31) and none for the right? I am using freesurfer-Linux-centos4_x86_64-stable-pub-v4.0.1 thanks, mishkin

mri_convert options
by Mishkin Derakhshan 14 Dec '07

14 Dec '07

Hi, I am having troubles getting the right options with mri_convert. I ran: recon-all -autorecon1 -i original.mnc -s subj1 recon-all -subcortseg -s subj1 I now want to convert aseg.mgz into aseg.mnc but in the same space and with the same orientation as my original.mnc file. My original.mnc file has the following attributes: double zspace ; zspace:comments = "Z increases from patient inferior to superior" ; zspace:step = -0.9765625 ; zspace:start = 127.418768256005 ; zspace:direction_cosines = -0.0275245718714001, -0.000514697647100001, 0.999620994692302 ; double yspace ; yspace:comments = "Y increases from patient posterior to anterior" ; yspace:step = -0.9765625 ; yspace:start = 146.850463958339 ; yspace:direction_cosines = -0.0186971433325, 0.999825193136882, -2.319984599e-08 ; double xspace ; xspace:comments = "X increases from patient left to right" ; xspace:step = 1.49999999999996 ; xspace:start = -95.4780255890689 ; xspace:direction_cosines = 0.999446254069973, 0.0186900576545041, 0.0275293837630133 ; short image(zspace, yspace, xspace) ; Any help would be much appreciated. thanks, mishkin

left and right wm neighbors error
by Matt Colvin 14 Dec '07

14 Dec '07

Dear FreeSurfer folks, We recently had an error occur while processing two brains in recon2. We are using FreeSurfer version 4.0.1 for these subjects. The error message in both cases mentions that mri_fill could not find points where lh and rh wm were "nbrs" (I assume this is short for neighbors). Upon inspecting the aseg.mgz files for both brains, I found that, while there were one or two spots in each brain where lh and rh wm voxels did touch, it was much less than in other version 4.0.1 asegs that we have processed and inspected. In other words, there were plenty of places where the connection between the l and r wm was mediated by the corpus callosum label, but almost none where the wm were direct neighbors. Is there any way known for fixing this problem? Could it be related to the new corpus callosum label in the version 4 segmentation which was not present in earlier versions? Thanks in advance for any help anybody might be able to lend. Here is the end of the error message: #-------------------------------------------- #@# Fill Fri Dec 14 07:12:09 CST 2007 /disk/conte_raid1/freesurfer/Geller/02681/mri mri_fill -a ../scripts/ponscc.cut.log -xform transforms/talairach.lta -segmentation aseg.mgz wm.mgz filled.mgz logging cutting plane coordinates to ../scripts/ponscc.cut.log...

problems
by 顏鳳賢 14 Dec '07

14 Dec '07

Hi, I had downloaded the freesurfer to my system (Linux Fedora Core 4) and had completed all the installation procedures. Question 1: I would like to convert analyze format to .mgz. What command line do I use? Can I type "mri_convert x249.img 001.mgz "? Question 2: When I type "recon-all -s x249 -nuintensitycor", it doesn't run and has a error" nu_correct." What would I do to resolve the problem? Question 3: It doesn't find talairach.xfm. What would I do to get the file? thanks~~ FreeSurfer problem report --------------------------------------------------------------------- FREESURFER_HOME: /usr/local/freesurfer Build stamp:

using BET prior to recon-all?
by Simon Rushton 14 Dec '07

14 Dec '07

I've been having problems with a few brains (errors during processing). I found advice on the web about running BET (the FSL brain extraction tool) prior to running recon-all http://lcni.uoregon.edu/mediawiki/index.php/SOFT:FSL_FreeSurfer I've tried this and that has helped. (Searching the mail archive I see that at least one other person on this list appears to be doing the same.) My question is, is this a sensible thing to do? I ask because looking at the output I see that at least one of the early processing stages appears to expect a non-stripped brain: mri_watershed -brain_atlas /Applications/freesurfer/average/ RB_all_withskull_2007-08-08.gca transforms/talairach_with_skull.lta T1.mgz brainmask.auto.mgz Does this suggest that I either should not try the BET trick or that if I do that I should make some modifications to the recon-all scripts? simon

Convert from {png,jpg} --> dicom
by Rudolph Pienaar 14 Dec '07

14 Dec '07

Hi - Does anyone have any advice/experience on converting/creating DICOMS from arbitrary image formats like png or jpg? Basically I have a set of post-processed png images that were derived from a set of DICOMS. I'd like to convert these png images back into DICOM again. Many thanks -=R -- Rudolph Pienaar, M.Eng, D.Eng / email: rudolph(a)nmr.mgh.harvard.edu MGH/MIT/HMS Athinoula A.

does one need a separate pediatric atlas for freesurfer?
by Binyam Nardos 13 Dec '07

13 Dec '07

Freesurfers, I had a couple of questions regarding your atlas. I'm working with a children and young adult subject population (ages 7-18). I'm interested in anatomical measures such as cortical thickness, and volumes of different structures. What are your thoughts on what atlas to use for these subjects? Does one need a separate (more representative?) atlas or can one use your default atlas... Also, can Freesurfer accomodate the use of custom-made atlases? appreciate your help, Binyam Binyam Nardos Cognitive Rehabilitation Research Group Washington University School of Medicine Box # 8505 4444 Forest Park Blvd St. Louis, MO 63108 Office: (314) 454-7795 Fax: (314) 286-1601 The contents of this e-mail message and any attachments are intended solely for the addressee(s) named in this message.
