OSX: New Psychtoolbox v 1.0.41 available now

1
Hi all,

OS X Psychtoolbox version 1.0.41 is now available from Psychtoolbox.org
here:
http://psychtoolbox.org/osx.html#download

This release improves on 1.0.40 by merging in contributions which we
received on the forum and by email. Special thanks to those who
identified bugs and contributed code. I have inserted additional
comments in C source and .m files acknowledging contributions.

Credits:
Mario Kleiner contributed many OpenGL bug fixes and optimizations and
uncovered the overflow error in reporting memory size.
Keith Schneider and Finnegan Calabro wrote Screen 'DrawDots' and
provided a demo.
Frans Cornelissen fixed AssertMex.
David Jones reported the memory size bug in DesribeComputer and
identified problems in TestFlip.m and TestDrawingStuff.m

A list of changes since the previous release appears here:

best,

Allen

Dear David,
 
I received the exciting news about the new version of Psychtoolbox for OS X. However, I use Psychtoolbox in Windows environment and as I brows through the pages in Psychtoolbox website, I get confused about whether I could use the new release in my PC or not.
 
The OS X page says that Windows users should 'eventually' be able to run their previous scripts with this version as well. What does this 'eventually' mean? Does it mean I will 'initially' be facing a huge mess which will be a consequence of running the new OS X in my PC?
 
In short, how much trouble should I expect if I upgrade my current Psychtoolbox with the new release? Is it advisable to do it at all?
 
thanks
bahador

As stated on the PsychToolbox main homepage, all
current new release are for MAC OSX only, not for
Windows. Any Windows updates will be done AFTER the
OSX release is stable.

Hence, you cannot update your psychtoolbox for Windows
with the recent new release.

A quick followup:

> Model Type "PowerMac7,2" with 2.00 GB RAM, bus clock 1.00 GHz

... actually, the bus speed is probably correct (1 GHz, half of
processor speed),
but the RAM is definitely wrong by a factor of 2.

Psychtoolbox 1.0.41 Bug Report

Overview:

1. DescribeComputer still contains numerical errors.
2. PsychTestsOSX/TestFlip reports wrong units.
3. PsychTestsOSX/TestDrawingStuffOSX still fails trying to open first
window
4. PsychTestsOSX/TestEventAvailOSX ... fails, no "EventAvail"
5. PsychTestsOSX/TestMATLABTimingOSX ... screen goes blank, never comes
back


Details:
- - - - -

1. DescribeComputer contains numerical errors.

The CORRECT answers (obtained from "About this Mac" under OS X):

Processor: Dual 2 GHz PowerPC G5
Memory: 4 GB DDR SDRAM


The Psychtoolbox ERROR output is given below.
Notice the RAM and bus are both too small by a factor of 2.


*********************** David Jones on Cascade ***********************
Dual-CPU Power Mac G5 at 2.00 GHz, Mac OS 10.3.7
Model Type "PowerMac7,2" with 2.00 GB RAM, bus clock 1.00 GHz
Psychtoolbox 1.0.41, 14 January 2004
MATLAB 7.0.1.24704 (R14) Service Pack 1
QuickTime 6.5.2

- - - - -

2. PsychTestsOSX/TestFlip reports wrong units.

The CORRECT units for frame frequency are Hz or frames/sec

The ERROR reports the frequency in "seconds".

- - - - -

3. PsychTestsOSX/TestDrawingStuffOSX still fails trying to open first
window

There is a typo. The number "2" must be replaced by the letter "s".

% ERROR
% w=Screen('OpenWindow', 2,[],[],32,2);
% CORRECTED
w=Screen('OpenWindow', s,[],[],32,2);

- - - - -

4. PsychTestsOSX/TestEventAvailOSX ... fails

First ERROR:

>> TestEventAvailOSX
??? Error: File: TestEventAvailOSX.m Line: 8 Column: 1
Illegal use of reserved keyword "end".

Second ERROR, (after deleting offending line):

>> TestEventAvailOSX
??? Undefined command/function 'EventAvail'.

Error in ==> TestEventAvailOSX at 3
[isThere, eventName]=EventAvail('keyDown', 'autoKey',
'mouseDown','mouseUp');
