SCREEN missing?

1
Hello,

I installed the PsychToolbox via the Installer to run under MATLAB 6.5,
but the SCREEN function seems to be missing. There is only a SCREEN.m
file containing help text, which will produce nothing but "Error: Too
many arguments." when called.

What am I missing?

Regards, Hendrik.

Is there any way for OS X Matlab 6.5 to work with the current
version of Psychtoolbox. I have downloaded the current version
of Psychtoolbox, and attempted to install with the installer. I kept
getting error messages saying that I didn't have a MATLAB folder
and that I needed at least Matlab 5.0, except that I have installed
Matlab and it is version 6.5. I proceeded to install manually with
the archived psychtoolbox, that worked but Screen doesn't seem
to be found, I always get an argument error.

I have read the other replies below, if the current version of
Psychtoolbox is not compatible with Matlab 6.5 then I apologize
for this posting, but if there is any development, could someone
please let me know?

Thanks,
Jonathan

No. The only way to use the OS 9 Psychtoolbox on OS X is with Matlab 5
in the OS X Classic Emulator. Because Classic does not accurately
reproduce the timing characteristics of a genuine Mac OS 9 system,
using the Psychtoolbox in Classic will not give reliable control video
timing.

I am re-writing the Psychtoolbox for OS X. There is a pre-release demo
available for download from Psychtoolbox.org. This pre-release
version is still missing a few key features, it is not yet ready to be
used for serious work.

Independently, at the University of Rochester, Ben Singer was
considering doing some work to Carbonize the OS 9 Psychtoolbox for OS X.
