PAM - PIE analysis with MATLAB

Introduction

PAM is a software package for quantitative analysis of fluorescence microscopy and spectroscopy data, with a focus on experiments using pulsed interleaved excitation. PAM combines many advanced fluorescence methods, including:

  • Fluorescence fluctuation techniques (FCS, FCCS, Pair-Correlation)
  • Single-molecule Förster resonance energy transfer (smFRET) in solution with multiparameter fluorescence detection (MFD)
  • Fluorescence lifetime imaging microscopy (FLIM) using the phasor approach
  • Image analysis and fluctuation imaging (ICS, RICS, tICS, N&B)

You can download the source code for PAM here.
The software is also hosted in a repository at https://www.gitlab.com/PAM-PIE/PAM. Please check there for the newest version.

Compiled versions can be downloaded using the following links:
Windows | MacOS
Additionally, check here for the newest version of the compiled software.

The manual can be found at http://pam.readthedocs.io.

Installing the stand-alone version of PAM

  1. Verify the correct MATLAB Runtime is installed (currently v9.1/ Matlab 2016b).

    You can download the MATLAB Runtime from the MathWorks Web site by from

    http://www.mathworks.com/products/compiler/mcr/index.html

    For more information about the MATLAB Runtime and the MATLAB Runtime installer, see Package and Distribute in the MATLAB Compiler documentation in the MathWorks Documentation Center.

  2. Download the compiled version of PAM for your Operating system (MacOS or WIN) from

    https://gitlab.com/PAM-PIE/PAMcompiled

  3. Unpack the files.

  4. Run the PAM.exe (Windows) or run_PAM.command (MacOS) to start the program. For MacOS, consult the readme.txt and how_to_create_shortcut.txt for additional information.

Installing and updating the open-source version of PAM

The open source version of PAM requires a valid licence for MATLAB (2014b or newer). Certain features further need access to tool boxes (curve fitting, image processing, statistics and machine learning, parallel computing) to work.

You can obtain and update PAM either through direct download from Gitlab, using the command line through Git, or by using the MATLAB Git integration.

Downloading from the repository

  1. Download the open source version of PAM from https://gitlab.com/PAM-PIE/PAM
  2. Unpack the files.
  3. Start Matlab and navigate to the PAM folder.
  4. Type PAM into the Matlab command line to start the program.
  5. To update, simply download the newest version and overwrite your files.

Using Git

Installing Git

Updating of PAM requires the installation of Git.

Downloading and updating using Git

  • To clone the repository, type git clone https://gitlab.com/PAM-PIE/PAM.git PAM to create a local copy of the repository in the folder PAM.
    • By default, you are checkout on the branch master, containing the stable version of PAM.
    • Should you need the newest updates, switch to the develop branch by typing git checkout develop.
    • To switch back, type git checkout master.
  • To update, simply type git pull to obtain the newest changes. Note that this will only update the branch that you are currently on.

Via MATLAB Git Integration

To use all features of the MATLAB Git integration, it is recommended to install Git as described above.

  1. Create a folder for PAM.
  2. Start Matlab and navigate to the PAM folder.
  3. Right click the 'Current Folder' panel in Matlab and select 'Source Control' and 'Manage Files...'.
  4. Set the 'Source control integration' to 'Git' and enter for the 'Repository path' https://gitlab.com/PAM-PIE/PAM.git
  5. Click 'Retrieve' to download the files automatically.
  6. To update the PAM Git repository to the latest version, simply type !git pull into the MATLAB command line.

To update, you can alternatively use the MATLAB Git integration, however the !git pull method is easier and quicker.

  1. Right click the 'Current Folder' panel in Matlab and select 'Source Control' and 'Fetch'.
  2. Right click the 'Current Folder' panel in Matlab and select 'Source Control' and 'Manage Branches'.
  3. Select the current branch form the remote repository, called 'origin'. If you work on branch master, select origin/master (or refs/remotes/origin/master).
  4. Click 'Merge' to merge the changes from the remote into you local repository.

Modification and development of PAM

Users are encouraged to modify the code of PAM for their individual needs and help with the development of new and the improvement of existing functionalities.

To report bugs or suggest improvements and bugfixes, please use the Issues function of GitLab. For this, a free GitLab account is required.

To contribute to PAM, please consult the contribution guide.
