MOLECFIT Development version

With the 2022 Public Release cycle now complete, the current Public Release version (4.2.2) is now up-to-date with the development version. And soon, version 4.3 will be released (which is infact identical to 4.2.2, except for the version number and documentation...). So while the following instructions to install the current development version ware still valid, there's  no actual point in doing so. Note the experimental support for additional instruments will also work for the public release version.

We are actively working on a new version of the MOLECFIT workflow with improved user friendliness and support for additional instruments. We expect to release this new version at the next ESO pipeline annual public release update (usually in May of each year).

In the meantime a "use at your own risk", "beta-version" of the development version is available. 

Subscribe to this article to receive notifications of updates.

Please follow the instructions below to install it.

First, if you don't have it already, install the public version of the MOLECFIT package (either via MacPorts or RPM package name = esopipe-molecfit-all, or the install_esoreflex script).

Second, make sure you have the software pre-requisites required for "pipeline source installations" and "KMOS and Molecfit pipeline source installations", see here.

Set up the environment for installation:

export MF_VERSION=

Then, please download the following file:

curl -O${MF_VERSION}

And then install it with the following command:

bash molecfit-${MF_VERSION}

Please see the updated tutorial in:


Please note, some of the newest features may not yet be documented...

Instructions to run the workflow are printed out at the end of the installation procedure.

You should try running the workflow on the tutorial data for one or more instruments. Simply start up the workflow and click the "play" button to run the tutorial for XSHOOTER. To try other instruments, just change the instrument name in the main canvas.

Please create a ticket if you have any trouble with the installation or running the tutorial. Please understand though, that as this is a "use at your own risk", "beta-version" of the development version, your ticket may not be handled as quickly as it would be for the Public Release version.
