Freesurfer - problem with automatic labeling of V1 using the Hinds method in 5.1.0
by Andrew Bock 08 Mar '13

08 Mar '13

Hello, I am having a similar problem to one described on the freesurfer mail archive, where I receive the following error when trying to identify V1 using the Hinds method (i.e. recon-all -s <subject> -label_v1): processing subject V1_average... MRISreadVertexPosition(white): could not open file /usr/local/freesurfer/ subjects/V1_average/surf/rh.white No such file or directory MRISreadOriginalProperties: could not read surface file white No such file or directory could not read surface positions from white No such file or directory As Prof. Krish Singh indicated in July, it appears the problem occurs when trying to open rh.white (or lh.white) from the surf subdirectory in V1_average, which doesn't exist. I have run recon-all -s <subject> -make all, but it returns "make: Nothing to be done for `all'." Any help you can provide would be greatly appreciated!

entorhinal cortex volume question
by Cat Chong 29 Jan '13

29 Jan '13

Hello experts, I am very new to freesurfer so please excuse my basic question: We want to get measurements of entorhinal cortex volumes on a group of people. I found these results listed in ?h.aparc.stats. I also noticed another ?h.entorhinal_exvivo.stats, with different results. Which should I use for a group analysis of entorhinal volume and surface area, and why are the results very different? very best regards, catherine

flipping surface data
by kelsi 04 Dec '12

04 Dec '12

Hi Freesurfers, Is there a tool to flip the orientation of surface data to the opposite hemisphere? We are working with stroke patients, and I would like to do analysis of the contralesional hemisphere of all the patients. However, this requires putting them on the same hemisphere for ttests, etc. I saw an earlier thread online about a program for flipping in the works, I was just wondering if this is now possible? Thank you! Kelsi

Re: [Freesurfer] integrating FSL and Freesurfer

Hi Doug Here are more detailed versions of my first two questions. 1) I used tkmedit to look at the mean_func produced by a gfeat analysis of one subject's three functional runs overlayed onto the anatomical image produced by recon-all on that same subject(bert/mri/orig.mgz). The registration matrix I used was the anat2std.dat that was produced by running reg-feat2anat on all three of the feat analyses from the individual runs. When I did this I saw that the mean_func image was outside the boundaries of the anatomical image. Correspondingly, when I overlayed the zstat.nii.gz from the gfeat analysis onto the anatomical image I had activation outside of the anatomical image brain. 2) Originally, I ran BBR on a subject that I had run Recon-all for. I used BBR to register the example_func.nii.gz to the bert/mri/orig.mgz. I had BBR output an fsl.mat. I then used ApplyXFM in fsl to apply BBR's fsl.mat to register the example_func.nii.gz onto a T1 image that had been created by converting bert/mri/brainmask.mgz into niftii with mri_convert. I tried it again, this time converting the orig.mgz to niftii. In both cases the example_func in T1 space image produced by ApplyXFM is rotated about 90 degrees and also inverted. This is viewed in fslview, The corresponding T1 images created by mri_convert are not. What can I do to allow me to use BBR's fsl.mat within ApplyXFM?

label transformation to MNI space
by Linda Douw 05 Jul '12

05 Jul '12

Hi all, I am trying to transform some labels from the aparc to masks in MNI space. Ideally, I would like to do this for each subject in my study individually (using their own rawavg.mgz and labels), but for now I started out with fsaverage. I first converted the label file into a nifti: mri_label2vol --label ./fsaverage/label/lh.entorhinal.label --subject fsaverage --temp ./fsaverage/mri/brainmask.mgz --o lh_entorhinal.nii.gz --identity And then put the nifti file containing the label into MNI space: mri_vol2vol --mov lh_entorhinal.nii.gz --targ MNI152_T1_2mm.brain.nii.gz --o lh_entorhinal_MNI.nii.gz --reg $FREESURFER_HOME/average/mni152.register.dat But when I open lh_entorhinal_MNI.nii.gz with fslview, the location is completely wrong. I checked the location with tkregister as well: tkregister2 --mov lh_entorhinal_MNI.nii.gz --reg /$FREESURFER_HOME/average/mni152.register.dat But here the entorhinal was also in the wrong place. Do you know how to fix this? Thanks, -- Linda Douw, PhD.

Re: [Freesurfer] ERROR: comparison in expression (FS with SGE)
by Xue, Feng 19 May '12

Sorry, I didn't notice that the reply address was not the list, I've done re-post it. Is there any method to check whether it is ok? For SGE, it might only write errors to dot e files instead of warnings. It seemed like a shell syntax error, however, I don't have that experience to check the recon-all script.

ICV
by Dusan Hirjak 23 Feb '12

23 Feb '12

Dear Freesurfer experts, I am a beginner in using Freesurfer. I was wondering if ICV should be treated as a potential confounder (such as age, education, chlorpromazine equivalents and duration of illness) in the statistical analysis of volumetric data/cortical thickness? Thanks in advance! Dusan

Tracula - bedpost failure
by Kiely Donnelly 10 Feb '12

10 Feb '12

Hi Everyone -- I've been having difficulty getting Tracula to run smoothly on our cluster. Similar to others on the listserv, the bedpost step was not creating the necessary files causing an error during the -path step. Based on previous posts, I ran bedpostx on the dmri directory. This initially seemed to work (I no longer received the message "1 slice processed" over and over), but for some reason the merged_ph1samples.nii.gz file is still not being created and I continue to run into an error when I run -path. It does create a merged_ph2samples.nii.gz output file. Any help would be greatly appreciated. Thanks, Kiely

Re: [Freesurfer] persistent bvecs error
by Alexander Lebedev 04 Feb '12

04 Feb '12

Hello Anastasia! Thank you very much for your response! My bvecs and bvals were created by saving excel spreadsheet as a tab delimited file on mac. I reformated my bvecs manually using "nano" and reran the preprocessing. Unfortunately, it exited with the same error. I'm providing you my reformated bvecs... I believe that the problem is not in reading of decimals, because running this step with "fake" bvecs of 1s and 0s (test_bvecs.txt) produces the same output with zeros, and everything seems to be ok with the tutorial dataset... What would you suggest? --- Best Regards, Alex

Hi Fred, yu probably checked the following already, but on the off chance you have not... Maybe you have set X11 to 256 color mode? Start X11.app (from /Applications/Utilities) go to the X11 menu, select Preferences..., switch to the tab called output and see what is selected for Colors. If it is set to 256 Colors you have your root cause, just switch to something higher and all should be fine. best Sebastian On May 9, 2010, at 9:00 AM, freesurfer-request(a)nmr.mgh.harvard.edu wrote: > Send Freesurfer mailing list submissions to > freesurfer(a)nmr.mgh.harvard.edu > > To subscribe or unsubscribe via the World Wide Web, visit > https://mail.nmr.mgh.harvard.edu/mailman/listinfo/freesurfer > or, via email, send a message with subject or body 'help' to > freesurfer-request(a)nmr.mgh.harvard.edu > > You can reach the person managing the list at > freesurfer-owner(a)nmr.mgh.harvard.edu > > When replying, please edit your Subject line so it is more specific > than "Re: Contents of Freesurfer digest..." > > > Today's Topics: > > 1. tksurfer/tkmedit display color fix in OSX 10.6?
