Other platforms

With pip

On other platforms, such as Linux, you will need a fairly recent python3 installation. We highly recommend that you create a python virtual environment first. There, install Quasar with pip:

pip install quasar

The above command will install all dependencies except PyQt. Install it with

pip install PyQt5

Then, run Quasar with:

python -m quasar

To open Bruker OPUS files, also install opusFC (only available for some platforms):

pip install opusFC

With conda

If you are using python provided by the miniconda / Anaconda distribution, you are almost ready to go.

As with pip, we highly recommend you create a separate environment for your Quasar installation.

Add two new channels:

conda config --add channels conda-forge
conda config --add channels https://quasar.codes/conda/

and set the channel_priority recommended by conda-forge:

conda config --set channel_priority strict

and install the quasar package:

conda install quasar

To open Bruker OPUS files, also install opusFC (only available for some platforms):

conda install opusfc
