===============================================
Gratin *(Graphs on Trajectories for Inference)*
===============================================

Gratin is a tool to characterize trajectories of random walks, i.e. motion driven by random fluctuations. This type of motion is observed at various scales and in a wide diversity of systems. 
While this package was developed for the purpose of analysing experimental data coming from photo-activated localization microscopy (PALM) experiments, nothing prevents it from being used on random walk recordings coming from other experimental setups and other domains !

To extract *summary statistics* describing trajectories, Gratin mixes two ingredients :

* an original neural network architecture using graph neural networks (GNN)
* a simulation-based inference framework

-------
Warning
-------

Gratin requires the ``pytorch-geometric`` package, whose installation depends on you CUDA version. 
Note however that you **do not need CUDA** to run Gratin, it works on CPU, it's only a bit slower. 
See `here <https://pytorch-geometric.readthedocs.io/en/latest/notes/installation.html>`_ to install it on your machine.
