question about stats
by Zachariah Holub 14 Jul '16

14 Jul '16

I have run various batches of freesurfer on our MRI scans. Now I want to take many of the stats files from all of our subjects and export them to one giant excel document. I would like to have a separate sheet for each kind of statistic (i.e. Sheet1=LH aparc.2009a; Sheet2=RH aparc.2009a; Sheet3=LH DKT etc...) and then have all of the subjects for that statistic type be included in the appropriate, single sheet. Is there a program that you are aware of that I can use to export the stat files to excel? I would greatly appreciate any insight or help you can offer as it is taking me forever to do this by simply copy and paste. Thank you in advance,Zach

Hello Freesurfers, What is the command line to load the control.dat file (control points) in freeview? We tried -cp but it didn't work. Thanks! Mihaela

mpr2mni305 failed
by Marita Partanen 14 Jul '16

14 Jul '16

Hi I have run recon-all successfully in the past, but now I am getting an error of mpr2mni305 failed, see transforms/talairach_avi.log. I'm running freesurfer-Darwin-lion-stable-pub-v5.3.0 on a Mac 10.10.5. This issue appears the same as a recent post http://www.mail-archive.com/freesurfer%40nmr.mgh.harvard.edu/msg47393.html but I couldn't see a solution. Any ideas? Here's the full error log: /Users/ophthalmologylab/Studies/Dyslexia_MRI/Intervention/freesurfer/DEGDY001B/mri /Applications/freesurfer/bin/talairach_avi --i orig_nu.mgz --xfm transforms/talairach.auto.xfm $Id: talairach_avi,v 1.9 2011/03/02 18:38:06 nicks Exp $ Darwin cfri2163m.bcricwh.lan 14.5.0 Darwin Kernel Version 14.5.0: Wed Jul 29 02:26:53 PDT 2015; root:xnu-2782.40.9~1/RELEASE_X86_64 x86_64 Fri Jun 17 13:29:22 PDT 2016 mri_convert orig_nu.mgz talsrcimg.img $Id: mri_convert.c,v 1.179.2.7 2012/09/05 21:55:16 mreuter Exp $ reading from orig_nu.mgz...

The MAC version is now fixed as well. It should be available for download in the next couple of days (Zeke can provide a better estimate).

Measuring cortical thickness
by Dev vasu 14 Jul '16

14 Jul '16

Dear Sir / madam, I have 50 subjects (25 healthy controls and 25 patients with BLVP) , I would like to know how could i generate cortical thickness maps for multi subject group analysis. The initial pre-processing with recon-all takes several hours for single subject, is there any alternate way to approach this problem in a limited amount of time?. Any help would be greatly appreciated. Thanks Vasudev

CVS question
by Michael Zeineh 14 Jul '16

14 Jul '16

Hi, I want to compare two populations using CVS so I can cross-register multimodal maps (e.g. ASL, FA, QSM) for volumetric comparisons. I’ve gotten CVS to work very well registering one subject to another, it really is impressive However, using the --mni option, it doesn’t work so well, perhaps because the atlas is so averaged together and smoothed out, the images look highly warped. I know I can pick a subject at random, and register everything to that, but that may induce some biases. The following website suggests I might try simply creating my own atlas (under the answers to Nov 2014 course questions): https://surfer.nmr.mgh.harvard.edu/fswiki/FsTutorial/QuestionAnswers <https://surfer.nmr.mgh.harvard.edu/fswiki/FsTutorial/QuestionAnswers> Seems like they register 40 subjects with each other for multiple iterations, average the brain together, then run recon-all on that. How does one actually do that, however? i.e. 1st round, register everyone to subject 1 … then what? Seems like somehow you would want a registration intermediate point somehow? Any help would be great, thank you! Michael Zeineh, M.D.-Ph.D. Assistant Professor, Dept. of Radiology Stanford University Lucas Center for Imaging

RB_all_2008-03-26.gca
by Gabor Perlaki 14 Jul '16

14 Jul '16

Dear all, Is it possible somehow to visually inspect the segmentations of the individual subjects used for the RB_all_2008-03-26.gca atlas? I can extract the means, priors and labels, but I am rather interested in the original MRI intensities and labels for the individual subjects. Best Regards, Gabor <petzinger.gabor(a)gmail.com>

how to calculate total pial surface area?
by Mihaela Stefan 13 Jul '16

13 Jul '16

Hello Freesurfers, We would like to know how to calculate the total pial surface area for each hemisphere. We extracted the surface area from the 34 ROIs per hemi from lh.aparc.stats but there is no total pial surface area in that file (only white surface area). Does it make sense to just add the 34 ROIs or there's a better way to extract that measure? Thanks! Mihaela
