Projecting a subcortical label to the surface
by Nillo, Ryan Michael R 22 Apr '19

22 Apr '19

External Email - Use Caution Hello FreeSurfer users, I have a subcortical segmentation that I want to project to the nearest cortical vertex. Would I use the mri_vol2surf command to accomplish this, or do I need to convert the segmentation into a label, then project the label to the fsaverage cortical surface?

freeview and complex values
by shahin＠nmr.mgh.harvard.edu 22 Apr '19

22 Apr '19

Hi Surfers, I am trying to use freeview to present retinotopy mapping in subcortical regions. I need to show complex (real and imag) values generated by a retinotopy analysis in a 'color wheel' format (similar to what tksurfer does). Any hint? _____________________________________ Shahin Nasr Assistant Prof. in Radiology Harvard Medical School Martinos Imaging Center, MGH Bldg 149, 13th street, Charlestown, MA 02129

mri_surf2surf help
by Larson, Kathleen E 22 Apr '19

22 Apr '19

External Email - Use Caution Hello FreeSurfer developers, I'm having trouble running the command mri_surf2surf, and I haven't been able to find a fix in the message archives (a similar question has been asked, but I couldn't find the answer). I am trying to convert the pial and white matter surfaces for a series of subjects back to the anatomical space. I have computed the registration matrix to transform the surfaces, but am having trouble with the mri_surf2surf syntax. This is the command I am trying to run: mri_surf2surf --hemi lh --sval-xyz pial --reg register.native.dat rawavg.mgz --tval lh.pial.native --tval-xyz --s <subjectID> and I get an error saying that --tval-xyz requires an input volume. (The syntax described on the website (https://surfer.nmr.mgh.harvard.edu/fswiki/FsAnat-to-NativeAnat) is out of date.) I have tried to use rawavg.mgz as the input volume, but then I get an output that can only be read as a scalar overlay, and I need an actual surface. When I try to use a surface as the input, I get an error saying that the file type cannot identified. Do you have any suggestions for what I am doing wrong? Thank you, Kathleen Larson Department of Biomedical Engineering Vanderbilt University 304 Featheringill-Jacobs Hall (425)-894-2005

mri_vol2surf error
by Nillo, Ryan Michael R 22 Apr '19

22 Apr '19

External Email - Use Caution Hello FS users, I am having a problem with mri_vol2surf. I want to project subcortical voxels onto the cortical surface. I found out that I can do this with the mri_vol2surf command. I am following the example given on the documentation, but I am getting this error: mri_vol2surf: could not read surface /working/ABCD/FS2/7583b4bc-b8fc-4390-8504-1a495b70d2bc//surf/lh.white. I am trying to project to the surface of the fsaverage. Does this error mean that FS is unable to find the fsaverage surface?

thresholded cluster output data
by Peters, Douglas G 22 Apr '19

22 Apr '19

External Email - Use Caution Hi Everyone, I'm new to freesurfer, and I was wondering if there is a way to output clusterwise threshold from Freeview (or any other tool) to illustrate cluster size, location, and significance? I understand that mri_glmfit-sim outputs cluster data after multiple cluster correction, but I was wondering if there is a way to get a similar cluster output prior to running multiple cluster correction. Thank you, DP

Problems with recon-all -s soft and hard fallures
by Camerino, .I.L. (Ileana) 22 Apr '19

22 Apr '19

External Email - Use Caution Dear Freesurfer experts, I am running recon all from the terminal of a linux machine: freesurfer-Linux-centos6_x86_64-stable-pub-v6.0.0-2beb96c. I tried recon all on an image dataset of small vessel disease patients. I tried the command on several subjects and I got the same outcome: a soft fallure. Please, find the recon all log in the attachment. Even though in the "recon all.log": it says: recon-all -s sub025 finished without errors, after checking the pial and white matter segmentations, very clear misplacement failures and part of dura mater are present (see attachment: segmenation misplacement and dura). I am also wandering how to avoid that white matter lesions are taken into the aseg segmentation? I checked the documentation and this kind of errors is not mentioned anywhere. Can be the case, that this error is due to the fact that these are clinical images? Can this problem be fixed? For sake of curiosity, I tried the recon all command on another dataset (stroke) and with these data I got an hard failure. recon all exited with errors: ERROR: talairach_afd: Talairach Transform: transforms/talairach.xfm ***FAILED*** (p=0.0573, pval=0.0034 < threshold=0.0050). (see second recon all o35403143 with errors) Please, can anyone give me some ideas how to fix both errors? Thank you in advance Ileana

Re: [Freesurfer] Lazy binding problem {Disarmed}

External Email - Use Caution Hello Lingyan, You can download an updated Mac freesurfer distribution from the following link,https://drive.google.com/file/d/1v2WwPg68id42NqfMeBTI3zijjto69_C1/view… After the download, you can uncompress the freesurfer_Mac.zip archive and put the freesurfer tree anywhere as long as you change the FREESURFER_HOME environment variable to point to it.  Then you would run the freesurfer script to setup the environment using that location.  For example, you can put the ../freesurfer tree under your home directory which you always have privileges to read/write to. $ cd $HOME$ pwd/Users/lwang  <— I am making up this path for this example ... then uncompress the zip archive in to your home directory, here assuming the archive was downloaded into your Downloads folder, $ unzip -d $HOME  $HOME/Downloads/freesurfer_Mac.zip … then in Bourne shell or bash shell you could do….  $ export FREESURFER_HOME=$HOME/Mac/freesurfer … and then to setup the environment… $ source $FREESURFER_HOME/SetUpFreeSurfer.sh Then you should no longer see the lazy evaluation error or be concerned with doing an install that needs admin privileges or whether or not SIP is on/off..(Setup instructions for the environment are also here, https://surfer.nmr.mgh.harvard.edu/fswiki/DownloadAndInstall) - R.

Extracting mean of values within a lable
by Sims, Sara A (Campus) 21 Apr '19

21 Apr '19

External Email - Use Caution Hello! I have a surface overlay that I want to extract the mean of the values within a label and export to a text file. How can I do that? I was looking into mris_anatomical_stats, but does mris_anatomical_stats let you tell it what file to pull the data from instead of just doing the standard extractions? Alternatively, I would be fine with just extracting all the values within the label and then finding the mean on my own. How could I extract all the values within the label and exporting to a text file? Thanks, Sara Sims
