pial to vtk conversion

[soichih]

app-freesurfer currently does a small post processing to convert lh.pial and rh.pial into .vtk format so that it can be loaded by browser to allow some basic / quick visual examination of the freesurfer output.

#generate brain vtk model (for visualization purpose)
if [ -f "output/surf/lh.pial" ]; then
    mris_decimate -d 0.1 output/surf/lh.pial lh.10.pial
    mris_convert lh.10.pial lh.10.vtk
fi

if [ -f "output/surf/rh.pial" ]; then
    mris_decimate -d 0.1 output/surf/rh.pial rh.10.pial
    mris_convert rh.10.pial rh.10.vtk
fi

I am wondering if we could take the these step out of app-freesufer and make it part of app-freesurfer-post. If we do this, we could also convert other files to .vtk or any web friendly format to visualize other files as well.. Do you have a suggestion?
