[Freesurfer] mesh size question

2008-10-22 Thread Tommaso De Marco
Hi all, I'm using the mri_watershed instruction to extract the skull and skin mesh, because I'm using them in a boundary element method, but the dimensions of these meshes are too big for my application (20480 faces and 10242 vertices for each ones). Do you know if there is a way to define a

Hi Tommaso, I am not sure about freesurfer, but why don't you simply use a standard tool for mesh simplification e.g. qslim http://graphics.cs.uiuc.edu/~garland/software/qslim.html probably there are more. Martin On Wed, 2008-10-22 at 14:48 +0200, Tommaso De Marco wrote: > Hi all, > I'm using t

Lan, Try adding this to the end of your /etc/X11/xorg.conf file: Section "Extensions" Option "Composite" "false" EndSection You will need to reboot your X11 server after doing so. Nick > I'm running stable version of freesurfer 4.05 on 64 bit ubuntu 7.10. > Every time when I tried to run

David, qdec output data is found in your $SUBJECTS_DIR/qdec directory. It is not in text format, as it is per-vertex data. The file 'sig.mgh' is the main significance result file. mris_convert can be used to convert that to text format if you need values at each vertex. Nick > > Dear freesurf

Hey everyone, I'm having some issues trying to run the volume pipeline using .BRIK input from afni (hence running mri_convert command directly). The problem occurs at the end of mri_convert at the very beginning when Freesurfer fails to write orig/001.mgz, and I'm not sure if I'm making a mistake
