talairach transformation error and general recon-all error
by JARED NIELSEN 17 Dec '13

17 Dec '13

Hi, I'm new to FreeSurfer and have been going through the tutorials, YouTube videos, and Mail Archive. I've run recon-all on a handful of scans with variable success. Some of the scans are processed after five or six hours without any problems, and the output looks good. Others are processed "without any errors" after a matter of minutes, and logically I don't see any output. Finally, others hit a hard error after a few minutes of processing during the talairach transformation step. I looked at the orig.mgz file (for the scan that failed at transformation step) through tkmedit, and it is a blank white rectangle. I don't see anything that resembles a head or brain. I've attached examples of each recon-all.log (i.e., good, bad, and bad_talairach). Any help would be greatly appreciated. Thanks, Jared

GLM p value display
by Celine Louapre 17 Dec '13

17 Dec '13

Hi all I am wondering what is the best to present GLM results in a table on top of the visual display. For the significant clusters after clusterwise correction, should we display the Max -log10(p) as in the summary file itself, or the p value directly, or a transformed pvalue like a Z score? Thanks for advices Celine -- Celine Louapre, MD Research Fellow at Massachusetts General Hospital Department of Radiology, MGH Building 149, Room 2301 13th Street Charlestown, MA 02129

After running a group comparison using qdec I wanted to use mc-z for multiple comparison correction I tried running: mri_glmfit-sim \ --glmdir MTA_ADHD_MJ2 \ --sim mc-z 1000 2.0 mc-z.negative \ --sim-sign abs --cwpvalthresh 0.999 \ --overwrite ERROR: dimension mismatch between X and contrast MTA_ADHD_MJ2/tmp.mri_glmfit-sim-9440/lh-Avg-thickness-Age-Cor.mtx X has 4 cols, C has 8 cols What does this mean and how to fix it? -- Jon Wieser Research Specialist UW-Milwaukee Psychology Department, Pearse Hall Rm 366 2441 East Hartford Ave Milwaukee, WI 53211 Phone: 414-229-7145 Fax: 414-229-5219

Tracula upgrading to Freesurfer 5.3
by Laura Christine Anderson 17 Dec '13

17 Dec '13

Tracula experts, I was hoping to upgrade to Freesurfer 5.3 in order to use the new motion detection feature of Tracula. The issue is that all of the preprocessing has already been completed in Freesurfer 5.2 with the older version of Tracula. Would I need to redo all the preprocessing in 5.3 in order to use the new motion detection feature? Thanks for your help! Laura Laura C.

Hi Bruce, I uploaded the data to your server. All files can be divided into 2 subjects. And one subject has incorrect segmentation (subject), the other has a multiframe ERROR(LJH_error). Thanks. All the best. 2013-12-17 Rujing Zha

Very strange error in surface reconstruction after a2-cp
by Paola Valsasina 17 Dec '13

17 Dec '13

Dear FS experts, I have a very strange error after running autorecon2-cp. I never saw this kind of error with previous versions of FS. I run recon-all -all on my subject, and obtained very good surface reconstructions, with the exception of few excluded wm voxels (see attachment called "before autorecon2-cp"). I added few control points throughout the entire image (for a total of 20 control points) and I run -autorecon2-cp -autorecon3 on the same subject. The output I obtain is very bad (see attachment called "after autorecon2-cp"). How is it possible that adding 20 control points causes such a surface distortions?!! I never had this error with previous FS versions. Thank you for any suggestion. Kind regards, Paola

Hi, I'd like to ask whether there exist any (implemented/objective) measure to identify a correct surface reconstruction beyond the visual inspection in order to identify gross defect or wm/gm boundary.

Fw: Re: unpacksdcmdir: specifies unpacking rules from the command-line ERROR
by Rujing Zha 16 Dec '13

16 Dec '13

Hi Bruce, Thanks Bruce. Would you please help me deal with another two problems? The 1st one is : There is a excellent segmentation in -surfs after editing the pial and running -autorecon-pial. Some voxels was removed from the brainmask.mgz in editing the pial. However the -aseg image still have those voxels which I have removed from the brainmask.mgz. Does this aseg image will influence my group thickness analysis if I donot process additionally? There are brainmask.mgz(pic 1) and aseg(pic 2) snapshots in the attachment. The 2nd one is : I could not visualize the inflated image properly by tksurfer. Here was the detailed describe: tksurfer yizhihui rh inflated I could see little thing in the tksurfer after typing the command above. The result can be got in picture 3 of the attachment and the standard output message can be seen in the picture 4. I had visualized it in the freeview tool by typing "freeview -f $SUBJETCS_DIR/yizhihui/surf/rh.inflated ". The result can be seen in picture 5. CentOS 5.8 is used in my server and I use "freesurfer-Linux-centos4-stable-pib-v5.3.0". Thanks in advance.

Re: [Freesurfer] problem creating annotation using mri_sample_parc?
by Markus Gschwind 16 Dec '13

16 Dec '13

Dear Bruce or someone else, would you mind answering a little more in detail, please? I am stuck. There is hardly any thread about the command mris_sample_parc, but I need this function. 1) This file called "cma_parcellation_colors.txt", is an option for mris_sample_parc. Where does that file come from? How am I supposed to create it? 2) What is missing if the loading of the created annotation file onto a surface (in freeview) gives the following error, repeating for infinity CTABfindAnnotation: ct was NULL No such file or directory CTABfindAnnotation: ct was NULL No such file or directory CTABfindAnnotation: ct was NULL No such file or directory CTABfindAnnotation: ct was NULL No such file or directory What does this error mean, at all? Thank you and please excuse my insisting!

how to do regression rather than group comparison in freesurfer
by ryu＠nmr.mgh.harvard.edu 16 Dec '13

16 Dec '13

Dear All, Does anyone know how to run regression (with covariates of interest) in freesurfer. I know people usually do group comparison but I need to do regression with a continuous variable. Or do I have to use SPM? Cheers, Jacky
