Hi there, I was trying to learn the freesurfer, I have hard time to download at the beginning, later after that, I also have no knowledge of how to import images and analyse them. I really need your help tremendously. Thanks, Haielom

FreeSurfer Version
by Rodrigo Perea 25 Jul '13

25 Jul '13

Is there any other way I can find the FreeSurfer version I am using? According to https://surfer.nmr.mgh.harvard.edu/fswiki/UserContributions/FAQ#Q.HowdoIkno… I have to run: recon-all -version, but I get the output below. Now the stable FreeSurfer Version is 5.3.0 so its not even close to the output. Any help? Rodrigo OUTPUT: recon-all -version $Id: recon-all,v 1.379.2.17 2011/05/20 22:48:18 nicks Exp $

different results between 5.1.0 and 5.2.0
by clarissa yasuda 25 Jul '13

25 Jul '13

Dear FreeSurfer Experts As in some other posts, I have also observed some differences between the two releases. The values from cuneus (thickness) are similar to the post from Ritobrato Datta, Ph.D. on 18 march. But I also observed some differences in volume of right / left thalami. Did anybody observe such asymmetry?? I am now running analysis with patients and controls on data from 5.2.0 and got surprised with this asymmetry. Here I am showing the average I obtained: R PALLIDUM L PALLIDUM R THAL L THAL RH_CUNEUS LH_CUNEUS 5.1 (350 SUBJECTS) 1580 1688 6701 6970.31 1.845 1.857 5.2 (115 SUBJECTS, subgroup of 350) 1519 1367 6520 7401 2.42 2.40 Is there any approach to correct it on 5.2 ?? Thanks in advance clarissa

I am not able to duplicate this error on my end using local data. A few things: 1) What happens when you type "nu_evaluate -help"? Do you get help output or does it crash? 2) Does this error occur for all subjects or just this one used for this particular recon? 3) Does the brain image look "normal", meaning is there anything obviously wrong with the input data, which you can see by opening it with Freeview? -Zeke On 07/24/2013 11:22 AM, Andrea Tateo wrote: > Hello zkaufman, > > thanks for your involvement > > Andrea > > > > ----Messaggio originale---- > Da: zkaufman(a)nmr.mgh.harvard.edu > Data: 24-lug-2013 16.52 > A: "Andrea Tateo"<andrea.tateo(a)virgilio.it> > Cc: <freesurfer(a)nmr.mgh.harvard.edu> > Ogg: Re: [Freesurfer] problem with nu_correct > > Hello Andrea, > > Can you please attach the entire recon-all.log file?

MRI dimensions different from [256x256x256]
by François Tadel 24 Jul '13

24 Jul '13

Hello, Is it possible to run recon-all without modifying the size of the input MRI volume? I have in input a volume [181x217x181], and all the steps of recon-all save it in a [256x256x256] volume. I tried skipping all the first steps to avoid this behavior (recon-all -all -nomotioncor -nonuintensitycor -notalairach) but it still re-interpolates my volume... For what I have to do, it would really help me if I can avoid this re-interpolation + padding. If this can't be done, can the output volumes be cropped to the desired size, while keeping the correspondence MRI/surfaces? Thanks, Francois -- François Tadel, MSc MEG / McConnell Brain Imaging Center / MNI / McGill University 3801 rue University, Montreal, QC H3A2B4, Canada

Binary mask of the skull
by Fotiadis, Panagiotis 24 Jul '13

24 Jul '13

Hi, I was wondering whether there was a command (or a flag in a command such as mri_binarize) that can give me the binary mask of my subject's skull. I was thinking of creating a binary ask of the subject's brain and then one of the brain and the skull and subtracting them, but I was wondering whether there is a faster way. Thanks, Panos

GCA atlas defined anatomical boundaries
by Zuzana Nedelska 24 Jul '13

24 Jul '13

Hello, I have attended short FSL/FreeSurfer course in New Zealand last year and have subscribed for mailing list, but in spite of all that I would I would appreciate very much to know. 1.) 1.)how GCA atlas that is used by FreeSurfer defines boundaries of subcortical volumes (especially amygdala and hippocampus). I work in Mayo Clinic Center for Advanced Imaging Research now and I need to know these details (if possible) this for publication methods. We use and cite FreeSurfer often, but never went into details like this. 2.) 2.)What is ment by region of ‘5th ventricle’ in FS aseg.stats outputs and LUTs color coding table? From anatomical point of view, I am not sure what 5th ventricle is 3.) 3.)Do I correctly understand that subcortical segmentation is based on manually labeled GCA atlas, and cortical parcellation is based either on Desikan-Killiany atlas with 33 ROIS/hemisphere, or Destrieux atlas with 73 ROIs/hemisphere? 4.) 4.)What is cortical region named ‘bankssts’ in Desikan-Killiany atlas? I would greatly appreciate your reply or suggestion where to find these information ASAP. Thank you, Zuzana Nedelska

asegstat values pre and post editing
by Claudia Dacquino 24 Jul '13

24 Jul '13

Dear Freesurfers, we recently processed a sample of adult patients and then we reran autorecon-2 and autorecon-3 after editing contol points, white matter and pial surface. We exported the asegstat table both pre and post editing, and we got different volumes for most of the subjects. How is that possible, given that the kind of editing we performed is not supposed to affect subcortical segmentation? Thanks a lot. Claudia
