MNI coordinates of all the vertices of fsaverage
by Sabin Khadka 01 Aug '16

01 Aug '16

Hi Doug, I tried to pick up from the thread below to get MNI coordinates of each destrieux parcellation region. https://mail.nmr.mgh.harvard.edu/pipermail//freesurfer/2013-July/032037.html I created label files from mri_annotation2label --subject fsaverage --hemi lh(/rh) --annotation aparc.a2009s --outdir label_destrieux # which works fine And I tried to get the coordinates of each labels using mri_surfcluster --in ~/subjects/fsaverage/surf/lh.thickness --clabel <label file> --sum <output file> --centroid --thmin 0 --hemi lh --subject fsaverage But, all left labels would produce the same coordinates and so does right labels. (I've attached few example files here with). Also, it says TalX, TalY, TalZ are these coordinates in MNI or Talairach? Thanks for help.

mris_label2annot
by Caroline Beelen 01 Aug '16

01 Aug '16

Dear FS, Sorry to bother again, but I'm currently in need for some quick help. Today, I also ran into another problem. I tried to display only few ROI's in Freeview instead of the whole brain. Therefore, I tried to create a new annotation file consisting of only few labels (from regions of DK-atlas) and I used the mri_annotation2label on my own created fsaverage to get these labels. This worked fine. Then I used the command of mris_label2annot to create the annotation file, but part of the command, --ctab aparc.annotation.ctab, is not recognized. Replacing it by -ctab fsaverage/label/lh.aparc.annot (file exists in the label folder of fsaverage) gives me the following error: CTABreadASCII: badly formed file. ERROR: reading fsaverage/label/lh.aparc.annot. I couldn't find, or create, any other aparc.annot file. What would be the right command (for the part of ctab) to get mris_label2annot working? Or is there perhaps a better way to only display certain ROI's in Freeview? (the latter I could still explore but assistance is certainly appreciated) Thanks a lot! Caroline

freesurfer 6.0 release date
by Fengji Geng 01 Aug '16

01 Aug '16

Hi fs developers, I am wondering if you have any estimation when fs 6.0 will come out. The reason that I ask this is because we are running some analysis using fs 5.1 and planning to switch to a more recent version of fs. If fs 6.0 will come out soon, we will probably hold and wait for it. If not, we will just switch to fs 5.3. Thanks! -- Fengji Geng

Hi, I wanted to follow up on the error that came up in the freesurfer dev version this past week. Has it been fixed yet? If so, has the link to the download page been changed? The one I booked marked does not lead me to the page anymore and I would appreciate it if you could direct me to the correct location. Thanks, Daniel

Cannot launch freeview

Hi Freesurfer Developers, I tried to run freeview but got this following error message. freeview.bin: error while loading shared libraries: libXss.so.1: cannot open shared object file: No such file or directory Freesurfer version: freesurfer-Linux-centos6_x86_64-stable-pub-v5.3.0 Linux version: NAME="Red Hat Enterprise Linux Workstation" VERSION="7.2 (Maipo)" ID="rhel" ID_LIKE="fedora" VERSION_ID="7.2" PRETTY_NAME="Red Hat Enterprise Linux" I tried "locate libXss.so.1", but returned nothing. Please let me know if you have the solution to fix this error. Thanks and best regards, Xiao Da Biomedical Engineer - Programmer Analyst II Functional Neuroimaging Laboratory Brigham and Women's Hospital 221 Longwood Avenue, Braunwald Building, Room LM116 Boston, MA 02115 xda(a)bwh.harvard.edu

mri_label2label error
by Aquino Domenico 01 Aug '16

01 Aug '16

Dear Freesurfer team, I'm trying to segment a pre-processed 3D PSIR volume. Everything seems to work correctly, however at the end of recon-all something goes wrong. The command "mri_label2label" returns the ERROR "No such file or directory\ mri_label2label: could not open label file...". Actually the file has not been created but I don't understand why. I checked the path for special characters, I checked the permissions and so on and it seems all ok. Which could be the issue? In attachment you'll find the recon-all.log file. Thanks a lot, Domenico ___________________________________________ Eng.

significance overlay Freeview
by Caroline Beelen 01 Aug '16

01 Aug '16

Dear FS, Yes, I'm running FS 5.3. :) How can I visualize the significance overlay (correctly)? Which command should I use to view a significance overlay in freeview in FS 5.3? See also my email below. Thank you very much in advance! Best, Caroline Hi Caroline, Are you running FS 5.3? The command on the webpage is based on the upcoming 6.0, I believe. So some of the command line options are not available in 5.3.

I used freeview ?h and tried certain commands alike, but they didnt work. When leaving out this part, I got another error that it failed to recognize annot_outline=1. Again, leaving this out too, freeview loads itself and the DK-regions become visible. However, nothing else seems to get activated, and even not when putting configure overlay (which is set to sig.mgh) to 1.3 as minimum and 3 as maximum. So basically nothing happens. > When looking at the command line it says that it implemented the colortable of DK-atlas (even twice), but it tells me nothing else. Also, after closing and reloading Freeview by using the similar command and then clicking on configure overlay the screen sometimes gets stuck, giving me the impression that something must be wrong with the command. > > Could you please help me out and provide me the right command-line for loading the overlay of the significance map of roi.lh.area.dyslect_basic.glmdir/dyslect? > > Thanks in advance! > > Kind regards, Caroline
