Can FCS Express integrate Python scripts?
Although the popular algorithms for high-dimensional data analysis in cytometry are already embedded into FCS Express and do not require any additional external software or “plugins”, we know that analysis might require custom algorithms for some advanced cases and researchers. If your research group needs additional flexibility then FCS Express allows you to run Python scripts via the Python Transformation pipeline step.
FCS Express can integrate Python scripts via the Python Transformation pipeline step. The Python pipeline step allows users to run their own Python scripts as part of FCS Express pipelines and work on the resulting output directly within FCS Express.
To set up your machine for Python transformations, please complete the following installation instructions.
Please note: in FCS Express 7.18, Python versions 3.11 and later are not yet compatible. The Python transformation cannot yet be run in the Mac version of FCS Express.
This step is required for PARC and TRIMAP, which are included in our FCSExpress Anaconda environment. It may also be required for other libraries.
- Go to this link: https://visualstudio.microsoft.com/visual-cpp-build-tools/ and click on Download Build Tools.
- Double-click on Vs_Buildtools.exe (it may be in your computer’s "Downloads" folder).
- If asked to "Allow Installer to make changes", click Yes.
- If you got a message about privacy, click Continue.
- From the Workloads tab (see screenshot below), choose Desktop development with C++.
- Under Optional components in the right pane (see screenshot below), only MSVC… and Windows 10 SDK (or Windows 11 SDK) are necessary. You may “uncheck” the others to save disk space.
- Click Install.
- This will take about 4 minutes to install and about 4.51 GB of space (8.15 GB on Windows 11) are required.
- When done, exit the Visual Studio Installer window.
- If you are prompted to restart your computer, please do so.
- You may now go on to the next step of Installing Anaconda, Python and Required Packages, found below.
Skip this step if you already have Python and the desired libraries installed on your computer.
If Anaconda is already installed on your computer, skip to the step below called "Launch Anaconda Navigator".
A convenient way to install Python is installing Anaconda, which is a distribution of Python for scientists (3.5 GB space is required).
- Follow the steps at the link below. You do not need to log in or sign up at any point when installing Anaconda and Python. If you are prompted to login or sign up, exit the pop-up window.
Once Anaconda is installed, we can create an environment to work with FCS Express. An environment is a collection of libraries of interest. Environments simplify library installations, avoid system pollution, sidestep dependency conflicts and minimize reproducibility Issues.
- Launch Anaconda Navigator from the Windows Start Menu
- Wait for the software to finish loading (wait for the blue animation to cease).
- If Anaconda asks to update, click Yes.
- If prompted to quit Anaconda, click Yes.
- If prompted again to update, click Update now.
- When the update is complete, click Launch Navigator.
- Click Environments.
- Download the FCSExpress environment here.
- In Anaconda > Environments, click Import.
- Select Local drive and click on the File Folder icon next to it
- Find the FCSExpress.yml file that you downloaded from the website. It may be in your computer’s "Downloads" folder.
- Click Open.
- Click Import.
- The FCSExpress environment has now been loaded into your Anaconda Navigator.
If the Python directory you wish to use in FCS Express is the Default, Registered Python on your computer, you may skip this step. The Default, Registered Python can be found in Windows RegistryEditor > Computer\HKEY_CURRENT_USER\Software\Python\PythonCore\3.X\InstallPath
- Launch FCS Express version 7.08.0018 or later.
- Open a New Layout
- Click File > Options.
- In the left pane, click Files/Directories
- Under Directory for Python (if not using Default, Registered Python), enter the path where the pythonXXX.dll is located for the environment you wish to use.
-
- If you have installed Python via Anaconda, (and wish to use the FCSExpress environment) enter the path of your FCSExpress Anaconda environment into your FCS Express user option (Files/Directories > Directory for Python)
- The path is found by hovering over the Anaconda environment (i.e. C:\Users\krittenbach\Anaconda3\envs\FCSExpress in the screenshot below)
- If you have installed Python via Anaconda, (and wish to use the FCSExpress environment) enter the path of your FCSExpress Anaconda environment into your FCS Express user option (Files/Directories > Directory for Python)
-
-
- If desired, the Python directory (for an Anaconda environment) can alternatively be found and copied by the following steps:
- Click on the desired environment name in the Anaconda Navigator.
- Click the green "play" button next to the environment name.
- Click Open Terminal
- Enter the following text: where python and press the Enter key
- Copy the path that contains your environment (i.e. C:\Users\krittenbach\Anaconda3\envs\FCSExpress)
- If desired, the Python directory (for an Anaconda environment) can alternatively be found and copied by the following steps:
-
-
-
-
- Paste the path into the FCS Express user option (Files/Directories > Directory for Python)
-
-
-
- If you installed Python from python.org, the path is likely similar to: C:\Users\XXXXXXXX\AppData\Local\Programs\Python\PythonXXX
- In FCS Express, click OK to apply the new user option.
- You can now try using the example scripts (provided on this page) in FCS Express.
- Once a Pipeline is created, the Python transformation pipeline step can be added from the + > Miscellaneous category.
- If the pipeline is already applied to a plot, you may get the warning below asking whether you want to disable the automatic execution of the pipeline and control the execution by the "Execute Transformation Pipeline" button instead.
- The Python Transformation pipeline steps will be added to the pipeline.
- Select the input parameters of interest.
- From one of the example scripts included on this webpage (below), highlight all of the text beginning with the "#". Press Ctrl+C or right-click>Copy.
- In the Python Script text box, right right-click and choose Clear Script to clear the example script .
- Ensure the cursor is in the left-most position of the first line. To confirm this, press the Home button on your keyboard.
- In FCS Express, click inside the Python Script text box and press Ctrl+V to paste the script. Note: Right-Click > Paste is not available.
- Click Save Script.
- The User Defined Options section of the Python Transformation step will then be populated based on the script code.
- Drag the Pipeline from the Transformations window onto the plot in the layout.
- If you do not have "Automatically Run Pipeline" checked, press Execute Transformation Pipeline in the pipeline root step.
- Running the pipeline may take a few seconds or several minutes, depending on the file size, chosen script and computer power.
- Once the transformation is applied to a plot and the run is completed, the output parameters generated by the pipeline will be accessible as any other classical parameters by clicking on the X and Y axis title of the plot of interest (e.g. Trimap 1 and Trimap 2 in the screenshot below).
Note: When the script is done running, the title of your plot will say "Pipeline transformed". In case your plot title does not contain the filename, you can check if the transformation is applied in the Overlay formatting dialog for that plot.
Some example scripts are presented below. Please see our full documentation on using the Python pipeline step in the FCS Express manual for more information on creating and implementing scripts.
In this example script, the Python Transformation pipeline step is defined to run PARC (PARC: ultrafast and accurate clustering of phenotypic data of millions of single cells; Shobana V Stassen; Bioinformatics, Volume 36, Issue 9, 1 May 2020).
Note: to run this script, Python, pandas and parc should be properly installed on the user computer.

In this example script, the Python Transformation pipeline step is defined to run HDBSCAN (Campello R.J.G.B., Moulavi D., Sander J. (2013) Density-Based Clustering Based on Hierarchical Density Estimates. In: Pei J., Tseng V.S., Cao L., Motoda H., Xu G. (eds) Advances in Knowledge Discovery and Data Mining. PAKDD 2013. Lecture Notes in Computer Science, vol 7819. Springer, Berlin, Heidelberg. https://doi.org/10.1007/978-3-642-37456-2_14).
HDBSCAN can be useful to identify clusters on UMAP plots. When HDBSCA is used for this purpose, creating a UMAP map with dense clusters (i.e. keeping the UMAP "Min Low Dim Distance" value low) will help HDBSCAN clustering.
More information on DBSCAN for Python can be found here.
Note #1: to run this script, Python, pandas, and hdbscan should be properly installed on the user computer.
Note #2: If noisy data points are detected by HDBSCA, they will be grouped under "HDBSCAN Cluster Assignment" equal to "1" in FCS Express.
Note #3: with large dataset, HDBSCAN might return a "Could not find -c" error. If that happens, setting core_dist_n_jobs to 1 might solve the issue.
