Psychophysics Toolbox Version 3 (PTB-3) is a free set of [[http://www.mathworks.com Matlab]] and [[http://www.octave.org GNU/Octave]] functions for vision research. It makes it easy to synthesize and show accurately controlled visual and auditory stimuli and interact with the observer. It has at least fifteen thousand active users (see [[PsychtoolboxOverview Overview]]), an active [[PsychtoolboxForum forum]], and is highly [[http://psychtoolbox.org/PTB-3/citations.html cited]]. PTB-3 is based on the Psychophysics Toolbox Version 2 (PTB-2) but its Matlab extensions (in C) were rewritten to be more modular and use ""OpenGL"". This Wiki describes the current version (PTB-3), which runs with Matlab 7.x and Octave 3.2.x on Mac OSX, Linux and Windows (see [[SystemRequirements System Requirements]]). The old PTB-2, for Mac OS 9 and Windows, still used in many labs, remains [[http://psychtoolbox.org/PTB-2/ available]] but is no longer developed or supported.

This Wiki refers to the current version (PTB-3), which runs under Mac OSX and Windows with MATLAB 7.x (see [[SystemRequirements System Requirements]].) Version 2 (PTB-2), for Mac OS 9 and Windows, remains [[http://psychtoolbox.org/PTB-2/ available]] but is no longer developed or supported.

The Psychophysics Toolbox (PTB) is a free set of MATLAB functions for vision research (Brainard, 1997; Pelli, 1997). The software runs in the MATLAB numerical programming environment. This Wiki refers to the current version (3.0 and higher), which is based on ""OpenGL"" and runs under Mac OS/X and Windows with MATLAB 7.x. Older versions run under Mac OS 9 and under Windows, but these are no longer under development.

=== Bug reports ===
Don't be shocked if you find a bug. Do tell us so we can fix it, but first please execute the //UpdatePsychtoolbox// command to make sure that you have the most recent (and most bug-free) release - Maybe your bug is fixed already.
The ideal bug report is a few lines of Matlab code that demonstrate the problem. Please also provide the exact version of Psychtoolbox (//PsychtoolboxVersion//). Sometimes it helps to provide the output in the Matlab window that PTB printed during execution. The //diary// command of Matlab allows you to record this output into a text file.

=== Version numbers ===
The Psychtoolbox version is a three digit number, e.g. 3.0.8. The first digit is always 3. We bump the second or third digit only for major releases, but these happen very seldomly. Usually we only update the //beta// or //stable// branch of PTB for the purpose of introducing single bug fixes, new features or incremental improvements. Such incremental updates are differentiated by their SVN revision number. Executing the command //PsychtoolboxVersion// should return the //version number, flavor and revision number// of your current Psychtoolbox. The command also prints a weblink which points you to the SVN online weblog where you can read in detail what has changed between different revisions.
We announce new releases. If you would like to be added to the mailing list, send email to psychtoolbox@psych.nyu.edu
=== Different versions of the Psychtoolbox ===
The most current version of PTB (Version 3.0.8) is available in two different flavors:
- **beta:** The beta branch provides the latest and greatest features, performance enhancements and bug fixes. All fixes for bugs and all enhancements or new features are first provided as part of the beta branch. These features have been successfully tested by the developers on their system configurations and should be reasonably safe for real world use and testing. However, there may be bugs that didn't show up in our setups and we only have very limited ressources (time and hardware) for testing, so new stuff needs to be exposed to real world use on many different hardware configurations. We rely on //you// for testing of new features and for feedback about problems or bugs.
- **stable:** Features that have been part of the beta branch for a couple of months without any reports about bugs or other problems, will be moved into the **stable** branch. Stable refers to the intention of stability and the moderate rate of change in this branch.
Before we apply potentially disruptive changes to //stable//, we do release a new version of Psychtoolbox, named //Psychtoolbox-x.y.z// with //x.y.z// being the version number. These releases are mostly meant to be checkpoints for extremely cautious users. We recommend sticking to the //beta// or //stable// branches unless you have good reason not to do so. The following two releases of old Psychtoolbox versions are available:
- **Psychtoolbox-3.0.7** A snapshot of the //stable// branch as of Friday, October 6th, 2006: Adds basic and limited support for movie playback on OS-X via Quicktime, some performance enhancements to the drawing functions and a few bug fixes. See [[http://svn.berlios.de/wsvn/osxptb/Psychtoolbox-3.0.7/Psychtoolbox/ReleaseNotes.m?op=file&rev=476&sc=1 the Release notes]] for more details.
- **Psychtoolbox-1.0.6** Snapshot from October 26th, 2005. First research grade version.

Several core Psychtoolbox functions are implemented as MATLAB Extension (MEX) files. These are compiled binary files, written in the C programming language. Instructions for downloading the source code can be found by typing //help UseTheSource// in Matlab. Additional instructions for modifying and compiling the source are [[InstallSource here]].

**Introduction**
**Download and Installation**
=== License ===
The source code for Psychtoolbox-3 is freely redistributable under the terms of the GNU General Public License (GPL) as published by the Free Software Foundation. Simply put, the GPL says that anyone who redistributes the software, with or without changes, must pass along the freedom to further copy and change it. By distributing the complete source code for Psychtoolbox-3 under the terms of the GPL, we guarantee that you and all other users will have the freedom to redistribute and change Psychtoolbox. The exact license text of Psychtoolbox is included as //License.txt// in the root folder of any Psychtoolbox-3 installation. An online version of the license can be found [[http://www.gnu.org/copyleft/gpl.html at the GPL page of the Free Software Foundation.]]
=== Downloading and Upgrading the toolbox ===
Information on dowloading Psychtoolbox Version 3 may be found [[http://www.psychtoolbox.org here]].
The toolbox is now stored on a publically accessible SVN (Subversion) revision control server. This allows us to simplify maintainance of the toolbox and to make updates immediately available to the user community. The new installation procedures connect to the server and retrieve and install the toolbox for you. Thus installing and updating are now pretty much automated. If you already have the //UpdatePsychtoolbox.m// script, just type //help UpdatePsychtoolbox// and follow the instructions. Otherwise, first make sure you don't have an old obsolete version by typing: //which DownloadPsychtoolbox// . If you find it, //delete// it, eg: //delete /Applications/Psychtoolbox/DownloadPsychtoolbox.m// . Then [[http://www.psychtoolbox.org/download/DownloadPsychtoolbox.zip download DownloadPsychtoolbox]], and add that folder to your MATLAB path: select menu item "File:Set path" and click the "Add path" button. Then type //help DownloadPsychtoolbox// and follow the instructions. You'll type either //DownloadPsychtoolbox('beta')// or //DownloadPsychtoolbox('stable')// to specify which flavor of the Psychtoolbox you want to use. New features reach the beta version much sooner than the stable version, but are not as throughly tested. You can update at any time by running //UpdatePsychtoolbox//, which is included in your new Psychtoolbox.

=== System requirements ===
**Operating System:**
- Apple Macintosh: Psychtoolbox is developed and tested under the latest versions of Mac OS/X (currently 10.4.7 and 10.4.8). We encourage users to use the latest version of OS/X (currently 10.4.x.) Generally, we have found that keeping up to date with the OS provides better performance. Although the toolbox continues, for the most part, to work under OS/X 10.3.9, we no longer test for compatibility with that OS and don't plan fix bugs or other issues related to it.
- Intel PC: Psychtoolbox-3 is known to run under Microsoft Windows 2000 and Windows XP. Other Microsoft OSs are untested up to now. We do aim to keep the toolbox working under these versions of Windows, but this is a lower priority than OS/X.
- There is also experimental support for the GNU/Linux operating system on Intel PCs in combination with Matlab 6.x or GNU/Octave 2.1.73. Due to our limited resources, we can only provide very limited support for this version. We are interested in feedback, and would welcome contributions from someone who wants to help develop this version.
**Runtime environment:**
- Recommended: [[http://www.mathworks.com Matlab]] 7.x (PTB is developed and tested for compatibility with this version of Matlab)
- Minimum configuration Matlab 5.x on Microsoft Windows, Matlab 6.5 on MacOS-X (Most basic functionality should work, but we do not test for or guarantee compatibility)
- On Linux, only Matlab 6.x and [[http://www.octave.org GNU/Octave]] 2.1.73 are supported for now.
**Additional software:**
- Apple Quicktime: Psychtoolbox needs Quicktime 7 on OS-X or Quicktime 6 or 7 on Windows for movie playback. We recommend staying up to date with the latest V7 releases of Apple.
- For video capture support on Windows, you need to install a Quicktime video digitizer component. The free [[http://www.vdig.com/ WinVDIG]] is known to work for USB webcams and standard consumer DV cameras with Firewire connector.
**Basic Hardware requirements:**
- Power-Macs: Any PowerPC based Macintosh computer capable of running MacOS-X 10.3.9 or later.
- Intel-Macs: Any Intel based Macintosh computer. As of now, there doesn't exist any official version of Matlab that runs natively on Intel-Macs. However, current Matlab 7.x versions are known to run successfully in the Rosetta software emulation mode when started from a terminal window with the //matlab -nojvm// switch. They will run without any graphical user interface though, and any Java based functions (e.g., GetChar) are disabled. There also exists a beta release of a native Matlab for Intel Macs. Psychtoolbox doesn't run with this beta yet, but we are making good progress in preparing a compatible PTB.
- Intel PCs: Any Intel compatible PC which is capable of running the 32 bit versions of Microsoft Windows 2000/XP or GNU/Linux.
**Graphics hardware requirements:**
Specific recommendations are difficult, as the required feature set is highly dependent on the kind of stimuli that you use. But in general you should not try to save money on the gfx-adapter, as performance of your stimulus script may depend much more on the horsepower of your gfx-adapter then on the horsepower of your cpu.
Users of the new Intel based Macs should be aware that some iMacs (e.g., Intel MacBook) use a //built-in Intel GMA// graphics adaptor. These gfx-cards are known to have a //very low graphics performance// and a //very restricted feature set//. They are cheap and sub-standard by any definition. If you like to take advantage of future advanced PTB features or want high performance we strongly recommend against buying anything that doesn't contain recent gfx-hardware from ATI or NVidia. See e.g., [[http://en.wikipedia.org/wiki/GMA_950 this Wikipedia article]] for further information.
- Absolute Minimum configuration: Any graphics card capable of basic support for hardware accelerated [[http://www.opengl.org OpenGL] with at least 16 MB of video RAM (VRAM).
- Reasonable minimum configuration: A graphics card that supports the GL_TEXTURE_RECTANGLE_EXT and (on MacOS-X if you make use of Quicktime movie playback) GL_UNPACK_CLIENT_STORAGE_APPLE extensions. All gfx-cards on OS-X except the ATI Rage (128/Pro/M) series do support these extensions. On M$-Windows, NVidia Geforce-2 and later are known to support these extensions as well. We recommend at least 32 MB, better 64-128 MB of VRAM if you want to run a dual-display setup or make use of textures or offscreen windows.
- Recommended configuration: The more recent, the better! Recent gfx cards improved continously in the following areas:
- Drawing performance: For example, state of the art gfx can draw more than 500.000 points per frame at a redraw rate of more than 100 Hz.
- Anti-Aliasing: Automatic high quality anti-aliasing and subpixel accurate positioning of drawing primitives is supported on recent gfx-adapters.
- Programmability: In the future, PTB will likely take advantage of modern programmable pixel shaders for features like built-in stereo presentation algorithms, on-the-fly image processing, or support for special purpose output devices like, e.g., high dynamic range displays.
- For dual display setups, we recommend using dual-head gfx-adapters (i.e. //one// card with two output connectors) instead of multiple separate adapters. Although the latter may work as well, PTB has only be tested with single card, dual-head configurations. For technical reasons, performance is expected to be higher and the potential of gfx-driver bugs is lower.

Additions:
=== Version numbers ===
The Psychtoolbox version is a three digit number, e.g. 3.0.8. The first digit is always 3. We bump the second or third digit only for major releases, but these happen very seldomly. Usually we only update the //beta// or //stable// branch of PTB for the purpose of introducing single bug fixes, new features or incremental improvements. Such incremental updates are differentiated by their SVN revision number. Executing the command //PsychtoolboxVersion// should return the //version number, flavor and revision number// of your current Psychtoolbox. The command also prints a weblink which points you to the SVN online weblog where you can read in detail what has changed between different revisions.
We announce new releases. If you would like to be added to the mailing list, send email to psychtoolbox@psych.nyu.edu
=== Bug reports ===
Don't be shocked if you find a bug. Do tell us so we can fix it, but first please execute the //UpdatePsychtoolbox// command to make sure that you have the most recent (and most bug-free) release - Maybe your bug is fixed already.
The ideal bug report is a few lines of Matlab code that demonstrate the problem. Please also provide the exact version of Psychtoolbox (//PsychtoolboxVersion//). Sometimes it helps to provide the output in the Matlab window that PTB printed during execution. The //diary// command of Matlab allows you to record this output into a text file.

Additions:
=== Different versions of the Psychtoolbox ===
The most current version of PTB (Version 3.0.8) is available in two different flavors:
- **beta:** The beta branch provides the latest and greatest features, performance enhancements and bug fixes. All fixes for bugs and all enhancements or new features are first provided as part of the beta branch. These features have been successfully tested by the developers on their system configurations and should be reasonably safe for real world use and testing. However, there may be bugs that didn't show up in our setups and we only have very limited ressources (time and hardware) for testing, so new stuff needs to be exposed to real world use on many different hardware configurations. We rely on //you// for testing of new features and for feedback about problems or bugs.
- **stable:** Features that have been part of the beta branch for a couple of months without any reports about bugs or other problems, will be moved into the **stable** branch. Stable refers to the intention of stability and the moderate rate of change in this branch.
Before we apply potentially disruptive changes to //stable//, we do release a new version of Psychtoolbox, named //Psychtoolbox-x.y.z// with //x.y.z// being the version number. These releases are mostly meant to be checkpoints for extremely cautious users. We recommend sticking to the //beta// or //stable// branches unless you have good reason not to do so. The following two releases are available:
- **Psychtoolbox-3.0.7** A snapshot of the //stable// branch as of Friday, October 6th, 2006: Adds basic and limited support for movie playback on OS-X via Quicktime, some performance enhancements to the drawing functions and a few bug fixes. See [[http://svn.berlios.de/wsvn/osxptb/Psychtoolbox-3.0.7/Psychtoolbox/ReleaseNotes.m?op=file&rev=476&sc=1 the Release notes]] for more details.
- **Psychtoolbox-1.0.6** Snapshot from October 26th, 2005.

=== Downloading and Upgrading the toolbox ===
Information on dowloading Psychtoolbox Version 3 may be found [[http://www.psychtoolbox.org here]].
The toolbox is now stored on a publically accessible SVN (Subversion) revision control server. This allows us to simplify maintainance of the toolbox and to make updates immediately available to the user community. The new installation procedures connect to the server and retrieve and install the toolbox for you. Thus installing and updating are now pretty much automated. If you already have the //UpdatePsychtoolbox.m// script, just type //help UpdatePsychtoolbox// and follow the instructions. Otherwise, first make sure you don't have an old obsolete version by typing: //which DownloadPsychtoolbox// . If you find it, //delete// it, eg: //delete /Applications/Psychtoolbox/DownloadPsychtoolbox.m// . Then [[http://www.psychtoolbox.org/download/DownloadPsychtoolbox.zip download DownloadPsychtoolbox]], and add that folder to your MATLAB path: select menu item "File:Set path" and click the "Add path" button. Then type //help DownloadPsychtoolbox// and follow the instructions. You'll type either //DownloadPsychtoolbox('beta')// or //DownloadPsychtoolbox('stable')// to specify which flavor of the Psychtoolbox you want to use. New features reach the beta version much sooner than the stable version, but are not as throughly tested. You can update at any time by running //UpdatePsychtoolbox//, which is included in your new Psychtoolbox.
