Bug in mrisComputeOriginalVertexDistances
by Andreas Schuh 14 Nov '15

14 Nov '15

Hi, I am just studying the FreeSurfer open source code (obtained from the read-only CVS, “dev” branch checkout instructions). It appears there is a slight mistake in mrisComputeOriginalVertexDistances. The following code computes the difference between v->y and vn->origy, where it probably should use v->origy as well. mrisurf.c:4093: xd = v->origx - vn->origx ; yd = v->y - vn->origy ; zd = v->origz - vn->origz ; Andreas

trouble with asegstats2table and aparcstats2table
by Elissa Ash 13 Nov '15

13 Nov '15

Dear Freesurfer support, I am very new to freesurfer and I thank you in advance for your assistance. I have been trying to run the group analysis tutorial (qdec) and I have encountered the following error messages. I was unable to generate the stats data tables in the tutorial and received the following types of error messages: 1) When trying to run asestats2table in qdec I get an error message that says that the subjects are not specified although they are. The $SUBJECTS_DIR is correct. I even encounter the same error when I just try to run asegstats2table --help (see below): tegmentum:group_analysis_tutorial gazzlab16$ asegstats2table --subjects 004 045 091 --meas volume --tablefile aseg_stats.txt File "/Applications/freesurfer/bin/asegstats2table", line 186 print 'ERROR: subjects are not specified (use --subjects SUBJECTS)' ^ SyntaxError: invalid syntax tegmentum:freesurfer gazzlab16$ asegstats2table --help File "/Applications/freesurfer/bin/asegstats2table", line 186 print 'ERROR: subjects are not specified (use --subjects SUBJECTS)' ^ SyntaxError: invalid syntax 2) When trying to run asestats2table I get an error message that says that at least one subject must be provided although they are. The $SUBJECTS_DIR is correct. I even encounter the same error when I just try to run aparcstats2table --help (see below): tegmentum:group_analysis_tutorial gazzlab16$ aparcstats2table --subjects 004 045 091 --hemi rh --meas thickness --tablefile aparc_stats.txt File "/Applications/freesurfer/bin/aparcstats2table", line 151 print 'ERROR: atleast 1 subject must be provided' ^ SyntaxError: Missing parentheses in call to 'print' tegmentum:group_analysis_tutorial gazzlab16$ aparcstats2table --help File "/Applications/freesurfer/bin/aparcstats2table", line 151 print 'ERROR: atleast 1 subject must be provided' ^ SyntaxError: Missing parentheses in call to 'print' I am not sure how to proceed.

Trackvis/ Diffusion Toolkit
by Alan Francis 13 Nov '15

13 Nov '15

Hi Anastasia: It was great to meet you at the connectivity course at Martinos. I have been using Trackvis to examine the white matter tracks between the anterior insula and the Dorsal ACC. In line with your instruction, I created ROIS at each of these regions. However, the WM tracks generated do not appear to connect. I have attached a screenshot. What is the command that one would use to connect the ROIs? thanks so much, best regards, Alan -- |~|~|~|~|~|~|~|~|~|~|~|~|~|~|~|~|~|~|~|~|~|~|~|~|~|~|~|~|~|~|~| *Alan N.

counting voxels in seeds
by André Schmidt 13 Nov '15

13 Nov '15

Dear FS experts, Using recon-all I defined 82 regions for a probabilistic tractography analysis. To address volume differences across regions, I like to normalize the obtained streamlines by the number of voxels in each regions. Is there an easy way to count voxels within each of my 82 regions? Thanks for your help André

Orientation of neural dipoles from Freesurfer
by Daniel Lindh 13 Nov '15

13 Nov '15

Hi, I am looking for a way of figuring out the orientation vector of the neurons within a voxel. That is, in which direction is the dipole of the neurons pointing at. This could be possible to calculate if there is a way of determining the position of the inner and outer layer for each voxel, which I am assuming is something Freesurfer does when it calculates gray matter thickness. If you could direct me to some relevant literature or an online tutorial I would be extremely grateful. best regards Daniel

Longitudinally processed thickness measures
by Worker, Amanda 13 Nov '15

13 Nov '15

Hi All, I have processed some longitudinal data (0, 1 week, 4 weeks) using the advised longitudinal stream. This is a healthy control sample and I wasn't expecting to see any differences in cortical thickness over the time points. Looking at some of the measures I have noticed that something doesn't seem quite right e.g. for one subject the insula measures: Cross-sectional Longitudinal Base A 2.835 3.016 B 2.721 1.864 C 3.050 3.107 3.098 The majority the longitudinally processed data looks reasonable, but there are a few instances where one timepoint looks completely different. Do you have any ideas if something may have gone wrong? I have attached the recon-all.log files for the template and the 3 longitudinally processed timepoints. Thanks in advance for your help, Amanda
