About The Project

Netcdfella is a command line interface (cli) tool for converting netcdf files to ASCII and JPG/PNG format, as well as creating graphs based on the vectors of the file.

Netcdfella supports two ways for converting documents at the time being:

• single/multi convert
• conversion upon creation

During the run of the cli the output types, the mapping dimension and variable can be selected aling with other options.

single/multi convert

You can convert a single file or all netcdf files in a directory on your command. This is the case of the single/multi select.

conversion upon creation

A directory can be selected to be watched by netcdfella. WHen a new netcdf file is created in that directory, it is automatically converted in the selected formats.

qnotify

In order to handle any amount of input documents in the case of watch. A producer-consumer queue is created in the module qnotify using the inotify library. In this case the producers are the directory events. This creates a buffer that can handle the set amount of concurrent document creations.

Use the README.md to get started.

Prerequisites

This software and tested for Python version 3.10.4.

If you need to manually install packages:

• requirements

  pip install -r requirements.txt
  

If you wish to make use of the pyproject.toml you need to install poetry:

• poetry

  curl -sSL https://install.python-poetry.org | python3 -
  

Installation

You can install from source or from pypi

Source

1. Clone the repo

   git clone https://github.com/nikfot/netcdfella.git
   

2. Install using poetry

   poetry install
   

3. Run netcdfella to see the help with available choices:

   netcdfella
   

   or

   netcdfella --help
   

PYPI

Usage

You can use the netcdfella to get a better description of the available choices:

```sh
netcdfella
```

or

```sh
netcdfella --help
```

convert

Use netcdfella to convert a single document or all documents in a directory:

```sh
netcdfella convert "/path/to/documents" -k "ascii,graph,scatter,marks" -md "flashes" -mv "radiance"
```

All choices for convert subcommand: Options: -o, --output-dir TEXT set the output directory for converted files. -k, --output-kinds TEXT set the output kind for conversion. -md, --map-dimension TEXT set the dimenion to use for mapping. -mv, --map-variable TEXT set the variable to use for mapping. -e, --exclude-variables TEXT comma separated list of variables to be excluded from conversion. --help Show this message and exit.

watch

Use netcdfella to watch over a directory and convert files upon creation:

```sh
netcdfella watch "/path/to/documents" -k "ascii,graph,scatter,marks" -md "flashes" -mv "radiance"
```

Options: -o, --output-dir TEXT set the output directory for converted files. -k, --output-kinds TEXT set the output kind for conversion. -md, --map-dimension TEXT set the dimenion to use for mapping. -mv, --map-variable TEXT set the variable to use for mapping. -e, --exclude-variables TEXT comma separated list of variables to be excluded from conversion. --help Show this message and exit.
