tksurfer wrong .annot
by Lemkaddem Alia 19 Dec '10

19 Dec '10

Hello, I'm working on the latest release of freesurfer 5 (freesurfer-Linux-centos4_x86_64-stable-pub-v5.0.0.tar.gz). Everything has been working fine until recently. When I open tksurfer to view the parcelation of my subjects, the region of unknown and CC is not recognized (it's named None). However, for "fsaverage" (see attachment) it's right but for "bert" and all my subjects it's wrong. I'm working on Ubuntu 10 and suspect that one of the package updates could have effected the tksurfer viewer. I have checked the segmentation of my subjects and it seems like all the regions are correct, so it's just a matter of tksurfer (I think). Have you faced this issue before? I'm thankful for all the help I could get. Thank you in advance, Alia

Cortical Classifier for PALS
by Lena Palaniyappan 18 Dec '10

18 Dec '10

I want to use the annot file for lobar areas in fsaverage to be mapped onto all of my subjects. As I don't want to disassemble the annot to single labels but generate lobar.annot for all subjects, I intend to use mris_ca_label -l fsaverage/label/lh.PALS_B12_Lobes.annot <subjid> lh lh.sphere.reg <classifier> subjid/label/lh.PALS_Lobes.annot For this purpose. What cortical classifier file should I use to map the different PALS atlases (at least - the two of them : Brodmann and Lobes) Cheers Lena _______________________________________________________ Lena Palaniyappan Clinical Lecturer & Honorary StR | Division of Psychiatry ( University of Nottingham) South Block 'A' floor| Queens Medical Centre | Nottingham | NG7 2UH This message and any attachment are intended solely for the addressee and may contain confidential information.

To Whom It May Concern: My name is Giovanni Rodriguez, I am a high school student working at the University of Miami in a research lab. My lab professor told me to work through the basics on my own and to download the tutorial and dataset. Is there anyway that I could find a dumb proof, step by step manual on how to download and work through Freesurfer? Thank you in advance, Gio

Trying to run recon-all on old raw data

Hello FreeSurfer experts, I am trying to run recon-all on old (back from late 1990's) raw MRI data. Each slice is in a raw format. When I try to execute recon-all, I get the error shown below: todd:~$ recon-all -subjid A_H -i > $SUBJECTS_DIR/adults_jp/A_H/slices/HA970313a1997031316500756 Subject Stamp: freesurfer-Linux-centos4_x86_64-stable-pub-v5.0.0 Current Stamp: freesurfer-Linux-centos4_x86_64-stable-pub-v5.0.0 INFO: SUBJECTS_DIR is /usr/local/freesurfer/subjects Actual FREESURFER_HOME /usr/local/freesurfer Linux neptune-ubuntu 2.6.35-23-generic #41-Ubuntu SMP Wed Nov 24 11:55:36 > UTC 2010 x86_64 GNU/Linux /usr/local/freesurfer/subjects/A_H > mri_convert > /usr/local/freesurfer/subjects/adults_jp/A_H/slices/HA970313a1997031316500756 > /usr/local/freesurfer/subjects/A_H/mri/orig/001.mgz > mri_convert > /usr/local/freesurfer/subjects/adults_jp/A_H/slices/HA970313a1997031316500756 > /usr/local/freesurfer/subjects/A_H/mri/orig/001.mgz $Id: mri_convert.c,v 1.166.2.2 2010/08/10 19:11:50 greve Exp $ reading from > /usr/local/freesurfer/subjects/adults_jp/A_H/slices/HA970313a1997031316500756...

How to adjust cortical thickness/area/volume measures from autorecon3
by Liukarl 16 Dec '10

16 Dec '10

Hello, Freesurfer experts: I found to report subcortical volumetric measure, ie, the volume of amygdale, people tend to use icv as a control variable. Is there any corresponding measure to correct the cortical thickness/area/volume results from autorecon3. Because we have priori hypothesis of hemisphere dichotomy of cortical structures, we need some control variable for each hemisphere. We want to use an overall measure for each hemisphere as a control variable. For example, to measure the group differences on rh_paracentral_thickness, we will use the rh_whole_thickness as a contral variable (which is the sum of the thickness measures of all the ROIs in the right hemisphere produced by Freesurfer). Similarly, to measure the group differences on rh_paracentral_area and rh_paracentral_volume, we will use the rh_whole_area and rh_whole_area as a contral variable respectively. Is this a valid approach to report our results? Thanks a lot! Karl
