nefis-cython

Neutral File System (NEFIS) Processing using a pre-built NEFIS library in Cython

This is a thin wrapper around a pre-built NEFIS Cython library which was provided by Deltares. This was made after several unsuccessful attempts at re-compiling the official OpenEarth nefis-python package on github using Cython. The .dll and .pyd files needed for this program are supplied in the releases tab.

Installation

Navigate to the repo folder and run this command in your (anaconda) prompt:

pip install -e .

Usage in Python script

import nefiscython as ne

f1 = 'trim-f34.dat'

# Get all data in a dictionary of dicts.
ff = ne.openfile(f1)
d1 = ne.getalldata(ff)
ne.closefile(ff)

# Convert to netCDF
ne.nefis2nc(f1)

Run from batch file in command line mode

rem Must have Python 2.7 installed with netCDF4 installed via conda.

rem SET PATH TO PYTHON 2.7
set py27=C:\Users\username\AppData\Local\Continuum\anaconda3\envs\py27

rem SET PATH TO NEFISMAIN SCRIPT. THERE IS A COPY ON THE K NETWORK DRIVE.
set nefispy=C:\Users\username\github\nefis-cython\nefiscython\nefismain.py

set PATH=%py27%;%PATH%

rem First argument is the function (nefis2nc)
rem Second argument is the input file name (.dat)
rem Run this batch file from the same directory as your input file.
python.exe %nefispy% nefis2nc trim-f34.dat
pause
