 The FastOMA workflow can be run directly without any installation using nextflow's ability to fetch a workflow from github. A specific version can be selected by specifying the `-r` option to nextflow to select a specific version of FastOMA:

 ### Singularity
 Since Docker needs administrator privileges (root access), [Singluarity](https://apptainer.org/index.html) (a.k.a Apptainer) is a good alternative. This can be installed using [Conda](https://anaconda.org/conda-forge/singularity) with `conda install conda-forge::singularity`. However, in most of the academic HPC cluster, singluarity is already installed and can be called with `module load`.
