-Run the below if `{emd_id}_coil.pdb`, `{emd_id}_helix.pdb`, and `{emd_id}_strand.pdb` are not present in the files downloaded from Cryo2StructData dataverse. The below program extracts coils, helices, and strands using [UCSF ChimeraX](https://www.cgl.ucsf.edu/chimerax/index.html) in no-GUI mode and saves them as seperate ``.pdb`` files.
