[Freesurfer] re qdec

2013-02-20 Thread Linn Mittlestein
Dear Freesurfer experts, I have a question about qdec...as it is supposed to be doing whole brain cortical analyses, how come one first has to generate statistical tables, and chose thicknesses of different regions from these tables? Is this just an option, rather than being necessary for qdec?

[Freesurfer] unusually long running time in autorecon2

2013-02-20 Thread Dawei Liu
Dear Freesurfer experts, I am running autorecon2 using Freesurfer verion 5.1.0 on Linux. For some subjects, it looks that the pipeline stucked in the middle of mri_cc and keeps running for days (without any error message). Last time when it occurred I thought it may be caused by some

I've noticed this at well when something goes wrong before mri_cc. It gets stuck in some kind of infinite loop. You might check that the linear and nonlinear registration worked correctly. Peace, Matt. From: Dawei Liu ldw70...@gmail.com Date: Wednesday, February 20, 2013 10:49 AM To:

Re: [Freesurfer] longitudinal processing

Hi Linn, did you ever solve this? you need to specify a name for the base and the tp1id and tp2id are placeholders for the id's of the corresponding 2 cross sectional time points. Don't typ;e the '...' So for example: recon-all -base linn-base -tp linn1 -tp linn2 -all linn1 and linn2

Hi Ziad, Thank you so much for the suggestions. However, I'm not really sure how to utilize any of them...So I guess more detailed help would be necessary for me to follow these suggestions. Sorry. I've also never actually used SUMA. Previously I was just using a 3dcalc command to bring aseg

[Freesurfer] Virtual Machine Disk Image Space

2013-02-20 Thread Kristina Nalbandian
Hello, I recently posted on the FreeSurfer mailing list, but received no reply. The main problem I am having is due to my virtual machine disk image, there isn't enough space. The virtual machine allows me to store up to four patient files, but there are some processes on FreeSurfer that

Re: [Freesurfer] changes in tracula in the upcoming freesurfer release 5.2

2013-02-20 Thread Sarosh, Cyrus
Anastasia, We have a set of MR data and all have the recon-all processing done in FreeSurfer version 5.1. Will we be able to use the results from the recon-all FreeSurfer version 5.1 for the new TRACULA version 5.2 or will we have to run recon-all in version 5.2 to use TRACULA version 5.2?

Hello I have run free surfer and co-registered with the rsfMRI via FSL (reg-feat2anat aseg2feat) When I extract the values (as per the matlab code below), I see NaNs in certain regions. Of the 19 datasets that I have analyzed I have see NaNs for the following labels 10061033

[Freesurfer] Gray Matter probabilistic Segmentation

2013-02-20 Thread Vincent Koppelmans
Dear FreeSurfer experts, I have some experience with FSL and SPM, but not a lot with FreeSurfer, so please bear with me. When I observe FreeSurfer segmentations, I see that images are binary (either a voxel belongs to a tissue class, or it does not) and not probabilistic. I want to obtain

2013-02-20 Thread Anastasia Yendiki
Hi Cyrus - Great question! The only thing that tracula utilizes from the freesurfer recon is the aparc+aseg, and since I'm told that there have been no changes from 5.1 to 5.2 affecting how the aparc+aseg is generated, you'll be fine using either 5.1 or 5.2 freesurfer recons as input for the
