Installing SEAMM#

SEAMM has three parts:

  • SEAMM itself, with the plug-ins you need, in a Python environment;

  • The SEAMM GUI for creating flowcharts, submitting jobs, publishing results etc., and

  • The JobServer, which runs jobs in the background, and the web interface, where you monitor jobs, browse the job directories and look at the results.

You can install everything on one machine, in which case you can do everything with SEAMM on that machine. Alternatively you can install the GUI on one machine – probably your personal machine – and the JobServer and web interface on a server, where your jobs will run. This is the recommended setup for a group of users, as it allows everyone to submit jobs to the same server and to follow the progress of all jobs. The easiest way to get started is to install everything on your personal machine so that you can test and run small jobs locally. Later, you can install SEAMM on any servers you have available and use the GUI on your personal computer to submit production jobs to them.

SEAMM is installed with the SEAMM Manager, a small tool that creates a Python environment for SEAMM, installs SEAMM and its plug-ins from PyPI, keeps them up to date, and sets up the desktop shortcuts and background services. It uses uv, a fast Python package manager that also supplies Python itself, so you do not need Python or conda to install SEAMM. The plug-ins for external codes such as MOPAC, Psi4, LAMMPS and DFTB+ install those codes with conda, so you only need conda if you want one of them on the machine. Installing SEAMM with the Manager walks you through it.

Note

Earlier versions of SEAMM were installed into a conda environment with the SEAMM Installer (seamm-installer). Such installations keep working but no longer receive updates. Moving from the SEAMM Installer explains how to move to the SEAMM Manager.

Important

SEAMM 2026.10 introduced a new flowchart format, 3.0. When you update an existing installation, also convert its jobs: Upgrading to flowchart format 3.0 explains how, and how to convert your own flowcharts.

Note

When you set up the web interface on a server, change the password of the admin account. Managing the Dashboard will walk you through this.
