This is molck - the molecule checker

Usage:

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.

%apprun OST
##############################################################################
# OST APP
##############################################################################
$OST_ROOT/bin/ost "$@"

%apphelp OST
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)
  -h, --help            show this help message and exit
  -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:

    singularity run --app Notebook <IMAGE> --help
