Re: Fwd: Talairach Failure Detection Help

Hello Everyone, I have tried using both the original dicom files and the renamed brain voyager files and although it fixes the Talairach error for some subjects I keep getting the same error for others (I haven't noticed a pattern here). Error message: #@# Talairach Failure Detection Mon Sep 15 11:03:51 PDT 2008 /Applications/freesurfer/subjects/2824mm/mri \n talairach_afd -T 0.005 -xfm transforms/talairach.xfm \n ERROR: talairach_afd: Talairach Transform: transforms/talairach.xfm ***FAILED*** (p=0.0000, pval=0.0000 < threshold=0.0050) Darwin guest-wireless-207-151-243-073.usc.edu 8.11.1 Darwin Kernel Version 8.11.1: Wed Oct 10 18:23:28 PDT 2007; root:xnu-792.25.20~1/RELEASE_I386 i386 i386 Any idea what could be the cause? many thanks, Marissa On Wed, Aug 20, 2008 at 9:08 AM, Bruce Fischl <fischl(a)nmr.mgh.harvard.edu>wrote: > yes, try the original dicoms.

Subject Averaging
by Richard Frye 30 Sep '08

30 Sep '08

Is there any documentation regarding the specifics of the process of subject averaging. Specifically, I am unclear on how the parcellation and cortical thickness is derived for the average subject. Is this information averaged from the input subjects or is it derived from the newly formed average volumes and surfaces? Thanks Rich -- Best Wishes, Richard E. Frye, M.D., Ph.D., F.A.A.P.

About the morphing parameters
by jorge luis 29 Sep '08

29 Sep '08

Hello all I would like to know the values of the metric distortion and deformation parameters (of the spherical registration algorithm) when creating an average subject and when registering the underlying population to the previous average. That is to say: What is the difference in the spherical morphing between the creation of the average subject and the alignment of the individual subjects to that average? In advance thank you Jorge Luis Bernal Rusiel Phd Student Laboratory of Functional Neuroscience University of Pablo de Olavide Seville.Spain

Error in recon-all -long on Linux
by Juergen Haenggi 26 Sep '08

26 Sep '08

Dear FS experts I run recon-all -long on a MacIntel Leopard and everything worked fine. When using the recon-all -long command on a Linux Machine (CentOS 32 bit) it runs untill the end ("recon-all finished without an error"), but there is an error.log file that is about 2 GB in size and it is too large to open. But I recognized an odd behaviour never seen before (see attachment). This behaviour lasted for minimum half an hour and maybe is responsible for the larger error.log file. Please help Thanks a lot Best regards Juergen ----------------------------------------------------------- Juergen Haenggi Ph.D. (Dr. des.)

which computer/server to buy?
by Narly A Golestani 26 Sep '08

26 Sep '08

Dear all, I see from previous posts to the list that it is possible to use servers to run freesurfer. I'm in the process of selecting a machine, and would appreciate any input anyone might have on which machine is optimal. In particular I'm concerned about eventual problems described on the mailing list earlier this month (see thread pasted below), regarding the ES1000 chipset that apparently comes with Dell PowerEdge servers (I am no expert with hardware issues such as these so this is all new to me!). Does this chipset come with all of these types of servers, or is it possible to order one with an NVIDIA card installed? Are there better alternatives wrt to which machine to purchase? thanks in advance for any input you might have, best, Narly. Re: [Freesurfer] tksurfer woes Mark J. Pearrow Fri, 12 Sep 2008 12:52:02 -0700 Hi all, FYI, this same problem has been bugging me for several months. Most ATI chipsets have a nice driver installer bundle that, once installed, will let you run tksurfer without a problem. However, this particular chipset, the ES1000, which is the chipset on Dell PowerEdge servers, is unsupported and seems to have been abandoned by ATI/AMD/whoever they are this week. If you happen to be unlucky enough to have Dell PowerEdge servers with this chipset and the need to run tksurfer, you're out of luck, until you put a slightly "better" graphics card in. I just managed to install an nVidia 8400GS (the x1 PCI-e version - the poweredge PCI-e bus is x8, which means it won't work with any of the most recent cards, but will work with slightly older x1 cards) and tksurfer works fine now. I can provide the gory details if you're in this boat. mjp On Sep 8, 2008, at 9:14 AM, Hoptman, Matthew wrote: Hi all, Im having trouble using freesurfers tksurfer program (I only get a sliver of the brain).

Freesurfer Command in Matlab

Hi, I'm trying to run the following command in through matlab: system(['mri_surf2surf --srcsubject average7 --trgsubject average7 --srcsurfval /space/schnook/1/users/yigal/projects/dti/data/old_recons/results/control_vs_sch_rh_average7_2mm_ttest.mgz --trgsurfval /space/schnook/1/users/yigal/projects/dti/data/old_recons/results/control_vs_sch_rh_average7_2mm_ttest.mgz --hemi rh --nsmooth-out 3']) And get the following error message mri_surf2surf: /usr/pubsw/common/matlab/7.4/sys/os/glnxa64/libgcc_s.so.1: version `GCC_4.2.0' not found (required by /usr/lib64/libstdc++.so.6) When I run the command from a terminal window, there's no problem. Any ideas? Thanks, Yigal

mri_convert: DICOM to nifti - multiple frames
by Watson, Christopher 25 Sep '08

25 Sep '08

Hi, I'm interested in getting multiple nifti images for each time point, similar to this old thread: http://www.mail-archive.com/freesurfer@nmr.mgh.harvard.edu/msg03317.html i.e., for a scan of 5 minutes and TR = 3, I would like 100 separate nifti images. This works fine when I set --out_type spm, but I'd like to start using the nifti format. The command I use: mri_convert.x86_64.dev -dicomread2 i545236.MRDC.1 -ot nifti1 "$SUBJ_DIR/image" only creates one file - image.nii. Is there a newer version of mri_convert that can do what I'm looking for? Here's the info: $./mri_convert.x86_64.dev --all-info ProgramName: mri_convert.x86_64.dev ProgramArguments: --all-info ProgramVersion: $Name: $ TimeStamp: 2008/09/25-14:47:29-GMT BuildTimeStamp: Jun 15 2007 11:06:50 CVS: $Id: mri_convert.c,v 1.144 2007/06/14 03:18:56 greve Exp $ User: matlab7 Machine: occipital Platform: Linux PlatformVersion: 2.6.9-55.0.6.ELsmp CompilerName: GCC CompilerVersion: 30300 Thanks, Chris

-normalization error
by Jeff Sadino 24 Sep '08

24 Sep '08

Hello all, I am receiving an error when trying to run autorecon1. When trying to step through it manually step-by-step, everything is fine up to -nuintensitycor. After running that command and looking at nu.mgz in tkmedit, the picture starts to fade out pretty bad above 120 intensity. When I lower the intensity down to about 30, I can see the picture just fine. Next, I skip -talairach (even though and run -normalization. But it exits with an error: [FSuser@cluster mri]$ recon-all -s 070046_S01 -normalization INFO: SUBJECTS_DIR is /data Actual FREESURFER_HOME /apps/freesurfer -rw-rw-r-- 1 FSuser FSuser 90352 Sep 24 16:10 /data/070046_S01/scripts/recon-all.log Linux cluster.mrilab.net 2.6.9-55.0.2.ELsmp #1 SMP Tue Jun 26 14:14:47 EDT 2007 x86_64 x86_64 x86_64 GNU/Linux #-------------------------------------------- #@# Intensity Normalization Wed Sep 24 16:15:19 HST 2008 /data/070046_S01/mri mri_normalize -g 1 nu.mgz T1.mgz using max gradient = 1.000 reading from nu.mgz... normalizing image... talairach transform 1.000 0.000 0.000 0.000; 0.000 1.000 0.000 0.000; 0.000 0.000 1.000 0.000; 0.000 0.000 0.000 1.000; INFO: Modifying talairach volume c_(r,a,s) based on average_305 MRInormalize: could not find any valid peaks mri_normalize: normalization failed Linux cluster.mrilab.net 2.6.9-55.0.2.ELsmp #1 SMP Tue Jun 26 14:14:47 EDT 2007 x86_64 x86_64 x86_64 GNU/Linux recon-all exited with ERRORS at Wed Sep 24 16:15:21 HST 2008 Also, I have some of the -talairach files from a previous run: [FSuser@cluster mri]$ ls transforms/ bak talairach.auto.xfm talairach.log talairach.xfm Any ideas?
