Hi ! I am trying to use Matlab and Psychtoolbox but, after the succeeded installation, when I write "ScreenTest" in Matlab, Matlab crashes. I think the installation was correctly done. Path are also well created. When I write "Screen" in Matlab, I have the list of functions. When I write "help Psychtoolbox" in Matlab, it seems well installed too. Any solution please ? Thanks !!

Try one of the demos, and you may see the error message if something is wrong. -Xiangrui > --- In [psychtoolbox@yahoogroups.com](mailto:psychtoolbox@yahoogroups.com), "bouton.sophie" \ wrote: > \> > \> Hi ! > \> > \> I am trying to use Matlab and Psychtoolbox but, after the succeeded installation, when I write "ScreenTest" in Matlab, Matlab crashes. > \> I think the installation was correctly done.
