-
-Options:
-  --complib=path    location of the compound library file. If not provided, the 
-    following locations are searched in this order: 
-    1. Working directory, 2. OpenStructure standard library location (if the 
-    executable is part of a standard OpenStructure installation) 
-  --rm=<a>,<b>      remove atoms and residues matching some criteria 
-    zeroocc - Remove atoms with zero occupancy 
-    hyd - Remove hydrogen atoms 
-    oxt - Remove terminal oxygens 
-    nonstd - Remove all residues not one of the 20 standard amino acids 
-    unk - Remove unknown and atoms not following the nomenclature
-  --fix-ele         clean up element column
-  --stdout          write cleaned file(s) to stdout 
-  --out=filename    write cleaned file(s) to disk. % characters in the filename are 
-    replaced with the basename of the input file without extension. 
-    Default: %-molcked.pdb 
-  --color=auto|on|off 
-    whether output should be colored
-  --map-nonstd   maps modified residues back to the parent amino acid, for example
-    MSE -> MET, SEP -> SER.

-The OST app exposes OpenStructure binary and can be used to run interactive shell
-and scripts.
-
-Usage:
-    singularity run --app OST <IMAGE> [ost options] [script to execute] [script parameters]
-
-Options:
-  -i, --interactive     start interpreter interactively (must be first
-                        parameter, ignored otherwise)

-  -v VLEVEL, --verbosity_level=VLEVEL
-                        sets the verbosity level [default: 2]
-
-If script requires some external files eg. PDBs, they have to be located in the
-path accessible via mounted volumes. By default Singularity mounts $HOME and
-goes to CWD. Thus this sould work as expected out of the box.

-%apphelp Notebook
-A Jupyter notebook palyground with OST and nglview.
-
-Usage:
-
-    singularity run --app Notebook <IMAGE> [options]
-
-The Jupyter notebook is run by default with `--NotebookApp.iopub_data_rate_limit=10000000`
-and `--no-browser` options.
-
-Useful options when running on remote server:
-    --ip=<Unicode> (NotebookApp.ip)
-        Default: 'localhost'
-        The IP address the notebook server will listen on.
-    --port=<Integer> (NotebookApp.port)
-        Default: 8888
-        The port the notebook server will listen on.
-
-Copy the URL to the browser and launch the notebook with OST kernel. This will
-load all necessary OST components just like in the OST shell. We also enabled
-the nglview widget to interactively view molecular structures and trajectories.
-For more details on how to use nglview see http://nglviewer.org/nglview/latest/.
-
-As the Singularity mounts $HOME by default Jupyter and Ipython config files
-are moved to separate directories. Proper environmental variables are also set.
-In addition, Jupyter is run in a separate virtualenv to not interact with possibly
-installed host version.
-
-To list of all available options:
