Existing Miniconda/Anaconda Installations

    conda create -n eman-deps-15 eman-deps=15 -c cryoem/label/py3 -c cryoem -c defaults -c conda-forge
  2. Use the activation command printed at the end of the previous command's run to activate the new conda environment

    conda activate eman-deps-15
    or
    source activate eman-deps-15

    conda deactivate
    or
    source deactivate
