mri_convert Segmentation fault (core dumped) lubuntu 13.04
by Joerg Pfannmoeller 02 May '13

02 May '13

Dear freesurfer administrators, recently upgraded our system to freesurfer 5.2 on lubuntu 13.04. After the installation I accounted problems when testing freesurfer. tkmedit did not display the subject bert, instead an error message was shown: tkmedit bert orig.mgz =================================== ERROR: A segfault has occurred. This is not your fault, : but is most likely an unrecoverable error and has : made the program unstable. : : Please send the contents of the file .xdebug_tkmedit : that should be in this directory to freesurfer(a)nmr.mgh.harvard.edu : : Now exiting... : Content of .xdebug_tkmedit is: tkmedit started: Thu May 2 08:44:48 2013 /usr/local/freesurfer/tktools/tkmedit.bin bert orig.mgz $Id: tkmedit.c,v 1.343 2011/03/01 01:41:22 nicks Exp $ $Name: stable5 $ Set user home dir to /home/mrt-physician/subjects Set subject home dir to /home/mrt-physician/subjects/bert Segfault Importing volume with MRIread xDebug stack (length: 5) 04: Volm_ImportData( this=0x284adf70, isSource=/home/mrt-physician/subjects/bert/mri/orig.mgz ) 04: Importing volume with MRIread 03: LoadVolume( iType=0, isName=orig.mgz, ibConform = 0 ) 03: Reading data into volume 02: ParseCmdLineArgs( argc=3, argv=/usr/local/freesurfer/tktools/tkmedit.bin ) 02: Loading volume orig.mgz 01: main() 01: Parsing command line arguments 00: 00: As I found in the web this problem seems to be due to mri_convert on fedora 18 (https://bugzilla.redhat.com/show_bug.cgi?id=905638) This bug is know reproduced for lubuntu 13.04.

Inputting specific talairach coordinates?
by Natalie Garcia 02 May '13

02 May '13

Dear FreeSurfers, I have a very basic question (which I'm hoping also has a basic answer!): I know that the Talairach coordinates provided in tksurfer are based on a conversion using MNI space, but I'm wondering: is there a way to input specific Talairach coordinates into Freesurfer to identify a specific ROI, then use those those coordinates can be examined across different surfaces (i.e. different subjects)? Any help would be greatly appreciated! All my best, Natalie -- Natalie V.

ROI analyses
by Tudor Popescu 02 May '13

02 May '13

Dear Freesurfers, I am doing an ROI analysis (group comparison) of cortical thickness, and I have some questions that I could use some help with. Many thanks in advance! Tudor 1) I used aparcstats2table to extract CT values for structures from the Destrieux atlas, but I cannot identify some important cortical structures among the names in that list. For example, I don't see anything corresponding to the Superior Parietal Lobule, or the Intraparietal Sulcus (the latter actually does appear but is coupled with another structure, under the name "lh_S_intrapariet_and_P_trans_thickness") 2) Can the same table (of the average CT of each cortical parcellation) be extracted using parcellations based on an atlas other than the Destrieux (e.g. the Harvard-Oxford, or the Julich)? 3) (I can't see whether there's a tutorial for this, as the main FS site seems to be down at the moment) How can a group comparison of CT be done inside a given ROI, and in what ways can the ROI be specified? I guess the command line version of QDEC would produce, in this case, the same contrasts as QDEC, but within the ROI as opposed to the whole brain 4) How do the results of these two different types of ROI group analyses differ, and is one of them more "correct" than the other: A) running the command prompt version of QDEC within the confines of a certain atlas-defined ROI, and looking at the resulting statistical map (clusters), as per question 3; B) extracting the CT values for that ROI for all subjects using aparcstats2table, and doing t-tests to look for a group difference.

Has anyone ever ran a post contrast sequence in FreeSurfer? Thanks, Ashley -- * *

FLASH params for mri_em_register
by Fred Dick 02 May '13

02 May '13

Dear all I'm having difficulties getting correct Talairach.lta's from synthetic flash volumes (Bruce, you are probably sorry you ever told me about this!). Basically the brain is over-scaled (bigger than it should be), which I think is happening because the contrast is so good (gm much darker than wm). Is there an example of how to use the -flash_parms flag, and what mri_em_register is expecting in the parameter file? Thanks, Fred

Exiting with errors but not sure why
by Borzello, Mia 02 May '13

02 May '13

Hi freesurfers! Great tutorial this week! I've recently run a recon, and it's exited with errors, but I'm not completely sure why. I've attached the error.log, but le tme know if I should attach another file. Thanks so much, Mia

mri_glmfit-sim - error of fwhm
by Sophie Maingault 02 May '13

02 May '13

Dear experts, I have a error message when I use the command : mdi_glmfit-sim glmdir X cwpvalthresh 0,001 cache 3 abs ERROR : cannot find /usr/local/freesurfer/average/mult-comp-cor/fsaverage_sym/lh/cortex/fwhm00/a bs/th20/mc-z.csd I don't understand why because to create this glmdir I use a file with fwhm = 5 mm and in the directory /usr/local/freesurfer/average/mult-comp-cor/fsaverage_sym/lh/cortex there are all values of fwhm (from 1 to 30) but not 0. I have to add an argument to specify fwhm used ? Thank you for your help ! Best regards. Sophie

display selected gyrus in specific color
by tulu＠ms36.hinet.net 02 May '13

02 May '13

Dear freesurfer experts, I try to combine some selected gyrus and display them all in red color, other brain structures will keep in gray color in freeview. I search for color lookup table page but don't know if I need to change the .annot file or not. How to correctly do that ? sincerely JL

Re: [Freesurfer] convert labels to volumetric masks
by limengsecret 01 May '13

01 May '13

Hi Doug, Thanks for your reply. I have downloaded some freesurfer files (.annot, .label, .curv, .w) about the specific regions. And I want to convert this files to volumetric masks, then the masks are used to overlay the normalized functional data, and according to the mask to define the specific region as roi. Thus, the problem is that, how I can achieve this goal, and which commands should I use. Thanks a lot.

That command will simply check a registration that already exists. doug On 04/29/2013 10:36 AM, limengsecret wrote: Dear FreeSurfers, I want to convert cortical labels to volumetric masks, the mask created are used to register with the normalized functional data and to define the roi, so could I run the following command? tkregister2 -mov sub/func.nii -noedit -s fsaverage -regheader -reg ./register.dat/ and the func.nii has been normalized (sub.nii) to the MNI space. And if the command is wrong, which command should I use? Best wishes, Meng
