Re: [vmtk-users] calling VMTK from MATLAB

[Luca A. <luc...@gm...>]

Hi Anouk, Ben,
 right, although there might be a chance that just doing

system('vmtk vmtksurfaceviewer -ifile foo.vtp');

might work, i.e. just specify the pipe right after the call to the vmtk script - the one that makes pypepad show up (above I just wrote "vmtk", but whatever you used that launched pypepad is fine).
