bioLEC 0.0.2

A Python interface to compute biodiversity metric based on landscape elevational connectivity.

# bioLEC - Biodiversity metric based on landscape elevational connectivity

This folder contains notebooks to compute **landscape elevational connectivity** described in Bertuzzo et al. (2016) using a parallel LECmetrics python code.

***

Notebooks environment will not be the best option for large landscape models and we will recommand the use of the python script: `runLEC.py` in HPC environment. the code will need to be

```bash
mpirun -np 400 python runLEC.py
```

The tool can be used to compute the LEC for any landscape file (X,Y,Z) and IPython functions are provided to extract output data directly from pyBadlands model.
