First install MambaForge (conda will work too but MambaForge is much faster at solving dependencies) If you decide to use conda replace all mamba references with conda

curl -L -O "$(uname)-$(uname -m).sh"
bash Mambaforge-$(uname)-$(uname -m).sh

Create a new mamba/conda environmenht

mamba create -n playmolecule
mamba activate playmolecule
mamba install python=3.10 ipython -c conda-forge

You can then pip install the PlayMolecule with

pip install playmolecule

Then add the following to your .bashrc file with the path provided by your administrator

export PM_APP_ROOT=/path/provided/by/administrator

Admin Installation#

Acellera will provide you with a license file for the applications and a Google service account JSON file. The administrator has to perform a few extra steps to completed the PlayMolecule installation for the users.

  1. Install the license file or license server

  2. Install the applications over Google Cloud

License Installation#

If you are intending to run the applications on more than a single machine you will need to setup a license server. For more information on how to set up a license server (Floating license) please see

Otherwise just place the license file on a location where all users can access it on the single machine.

Application Installation#

To install the applications for the users you need to follow these steps:

  1. Install Google Cloud CLI to authenticate with Google Cloud where the app images are stored. Installation instructions can be found here:

  2. On the gcloud init step of the above instructions authenticate with any account you wish.

Install the following pip packages in addition to playmolecule which are needed for the admin installation.

pip install playmolecule questionary google-cloud-storage==1.35.0 tqdm

Choose a path where PlayMolecule will be installed. If you are running the applications in a cluster like SLURM choose a path which is accessible from all machines (i.e. on a shared file system). Otherwise choose a path on your local machine which is accessible to all users on that machine. Set up the path in your .bashrc file as follows:

export PM_APP_ROOT=/path/provided/by/administrator

To create the PlayMolecule installation open an ipython console and type the following:

from playmolecule import update_apps

This will start an interactive installation of PlayMolecule to guide you through setting up everything. At some step it will ask you for the service account JSON file which Acellera has provided you with for downloading the applications.

Later if you want to update the applications again to their latest versions you can run the following commands:

from playmolecule import update_apps
