30 gigabyte recon-all.log file after protocol error
by Max Gunther 23 Jul '10

23 Jul '10

Dear FreeSurfers, I am new to FreeSurfer and just trying to run some simple volumetric analysis and I get a "Protocol error". I went to look at the log file and it is 30 gigabytes in size so something is going awry here... Is there a way to break this error down further to understand what may be going wrong? I am running FreeSurfer in the Oracle virtual machine. The command that I am running after I set up the environment and convert the file structure is recon-all -s TED -all. Then I tried recon-all -s TED -autorecon1 I have tried this on a couple of different subjects and have tried deleting and cleaning up the directories and remaking them, checking to make sure that I have enough hard drive space etc., but I keep getting the same error messages. Below are the error messages that I am receiving. Thanks for you time.

Any update on releasing the source for FreeSurfer?
by Alex Waite 23 Jul '10

23 Jul '10

Hey Everyone, I searched through the archives and it seems to be that there is an intent to release FreeSurfer as open source eventually. However, the most recent post about that that I could find was from a year or two ago. Is there any update on this or plan for when this will happen? The reason why I ask is that we're looking to run FreeSurfer on Debian based systems, and it doesn't seem that you provide packages for those systems. I would be happy to compile and package this software and make it available to the community if the source was available, or made available. Thank you for your time. I look forward to hearing back from you. ---Alex

Re: [Freesurfer] Fwd: Plotting functional data on surface
by Corey Keller 23 Jul '10

23 Jul '10

Hi Freesurfers, Thanks for all of the help so far. I just have one more quick follow-up question. Just to remind you I was attempting to plot a functional map on a pial surface in matlab. The solution was to index the functional map so that I just color-coat the pial surface accordingly instead of the usual gray. We are now trying to transform this functional data so that it will plot on the pial surface of the average subject, fsaverage. Any help will be much appreciated. Thanks again. -Corey On Fri, Jul 2, 2010 at 2:27 PM, Corey Keller <corey.j.keller(a)gmail.com> wrote: Hi, I figured out how to plot it on my pial surface. Here's my code if anyone is wondering.

functional ROI analysis for DLPFC
by Adam Nitenson 23 Jul '10

23 Jul '10

Hi all, I am trying to use func2roi-sess to analyze functional ROI data for the left and right DLPFC, but these are not listed as labels on the FreeSurferColorLUT on http://surfer.nmr.mgh.harvard.edu/fswiki/FsTutorial/AnatomicalROI/FreeSurfe…. Do I need to create my own ROI labels for these? I tried the command "func2roi-sess -roidef DLPFC -analysis fmcsm5_functionals -c Cond1v7 -s FB0011046AA -maskthresh 1.3 -maskmap sig.nii " which actually ran to completion and created a DLPFC folder in my subject file, but I really have no idea if this helps at all with my goal of, to quote my PI, "look at the dorsolateral prefrontal cortex ROI data, which will generate a single value for the average activation within the right or left DLPFC for each subject, during each condition".

Freesurfer failure with diseased brains
by H. Reynolds 23 Jul '10

23 Jul '10

Hi, I've been using Freesurfer's 'recon-all' function to process T1 datasets of healthy age-matched, MCI and early-onset Alzheimer's brains. It has been successful with the two healthy controls I've tried, but only half of the MCI and EAD brains work - Freesurfer fails and exits 'with errors'. We think that the reason for this may be due to the severe atrophy going on in the MCI and EAD brains, but are not sure - does anybody have any suggestions for why Freesurfer keeps failing? Thanks, Heather

segmentation output not in alignment

Dear all I put a T1w image through the recon-all process and it completed without errors, but the segmentation output (aparc.a2009s+aseg) does not line up with the subjects own brain.mgz or orig.mgz. I have had a similar problem with other T1w images that I've used. Any ideas why this might be and how to correct? Many thanks for your help Rumana --

We don't understand why there isn't the right side of the brain. Any suggestions? Thank you all.

Registration with fsaverage
by Corey Keller 22 Jul '10

22 Jul '10

Hi Freesurfers, I am trying to check the spherical alignment of an individual subject registered to fsaverage via lh.sphere.reg. I am using the following command in tksurfer: tksurfer CL lh sphere and get the error code below. Could someone let me know what I am missing here? Should I be using tkregister2 instead? And if so, what is the correct command to use? Also, it says it can't find the talairach file but talairach.xfm is in the subject's transform folder. Thanks in advance.

strange result in qdec and mri_glmfit
by Joana Braga Pereira 22 Jul '10

22 Jul '10

Dear Freesurfer experts, I've just finished running a qdec analysis of a comparison of cortical thickness between controls and patients with 2 covariates and found a strange result. When i set the threshold at FDR some clusters appear in red which are the corrected results from my analysis. However the rest of the cortex acquires a grey homogeneous colour that seems strange. When i check the thresholds in qdec i found that they were set from 100 to -100... Any ideas why this happened? Afterwards i did the mri_glmfit simulations with these results from qdec and saw that the summary cluster table indicated a single bilateral cluster of more than 70 000 mm size, as if the program considered the homogenous grey colour as a significant result between groups. Any help would be greatly appreciated. Best, Joana

Creating a label
by liang wang 22 Jul '10

22 Jul '10

Hi, I can create a label file from either ?h.aparc.annot (using mri_annotation2label) or aparc+aseg.mgz (using mri_cor2label). However, I find the two same label are shown different using tksurfer. Specifically, the label created by mri_annotation2label display compact and clear, whereas one obtained by mri_cor2label seemingly includes more tiny, disperse vertices. Does anyone know what's happening? Thanks.
