Hi All, Is there a way to combine multiple binary volumetric masks into a single binary volumetric mask in freesurfer ? Please let me know. Thankyou Subha

Download difficulty
by Michael Paldino 30 May '13

30 May '13

Hello all, I seem to be having some difficulty downloading the freesurfer software to my MAC computers. I have tried my laptop (MacBook pro, I don't remember the version but it is approx. 10.3) as well as a desktop (imac, mac osx version 10.8.3) and also tried two different networks. I have tried just clicking on the link (on your download page) as well as the curl -O command line. I get an NSURL error everytime, prior to any significant downloading. I have not have this difficulty with other freeware downloading to the same computers or on these networks. Any thoughts? Thanks Mike

Hello Doug, Thank you. Will fscalc work with volume mask ? You wrote .mgh. mgh is surface data, right ?

How to determine a smoothing kernel size for surface that is approx. equal to 4mm in volumetric data?
by Glen Lee 30 May '13

30 May '13

Hello Freesurfer users I'm trying to replicate my earlier findings in 3D space by warping the data into surface using freesurfer. Previously, the 3D data were smoothed using 4mm FWHM kernel and I'm wondering what size of smoothing kernel for 2D would be equivalent to 4mm for volumes. Any help would be greatly appreciated. Glen

Re: [Freesurfer] mris_divide_parcellation color table error (fwd)
by Bruce Fischl 30 May '13

Hi Tina is this (attached) more what you wanted? If so, then I think you want to use mris_make_face_parcellation instead of mris_divide_parcellation. I can't remember what they used in that paper, but in mris_divide_parcellation I try to have the different units within a parcel have similar colors (which evidentally fails when you split it so finely) Bruce On Thu, 30 May 2013, Tina Jeon wrote: > I am running version 5.3- the latest version.

WARNING: tcsh v6.17.06 has an exit code bug!
by Andrew Bock 30 May '13

30 May '13

Hello everyone, I just updated to Freesurfer 5.3.0, my OS is Ubuntu 12.04. When I run 'recon-all -i <T1 image> -subjid <subject name>' I receive the following error: WARNING: tcsh v6.17.06 has an exit code bug! Please update tcsh! The directory structure appears to be set up correctly, and the command finishes without error. I do not receive this error when using Freesurfer 5.1.0. I have yet to run 'recon-all -all -subjid <subject name>' in 5.3.0. Any ideas on what produces this error? is it safe to ignore? Thanks in advance, Andrew

Exporting surface coordinates to Nifti header space
by schreibm＠informatik.hu-berlin.de 30 May '13

30 May '13

Hi Freesurfers! I'd like to load my original Nifti T1 image data (subject.nii) and the wm/gm-surface coordinate data (for instance lh.pial) in matlab as vectors in the same coordinate system. If I do it in the naive way, i.e. [x,y,z,1]=[i,j,k,1]*sform' for the Nifti coordinates resp. freesurfer_read_surf(...) for the surface nodes, then surface and Nifti appear not to be coregisterred. It looks as though there would be a spacial shift missing. Although having tried several matrices I cant figure out which is the one to choose. Inspecting the Data by Freeviewer I observe the same spacial shift, inspecting it by 'tkmedit subject_id brainmask.mgz lh.pial' everything is fine. Could you tell me, which transform I have to apply to the surface coordinates? That would be really nice. Thanks and best Regards, Max
