==========
Chemiscope is a tool for interactive exploration of databases of materials and
molecules, correlating local and global structural representations with the
properties of the systems. Chemiscope files can be viewed `online
`_, generated using a `python library
`_ and used inside jupyter notebooks or
sphinx documentations, which is how it's used in the cookbook examples. You can
check the `documentation `_ and the `github
repository `_.

:alt: This notebook analyzes the structures of 264 polymorphs of ROY, from Beran et Al, Chemical Science (2022), comparing the conventional density-energy convex hull with a Generalized Convex Hull (GCH) analysis (see Anelli et al., Phys. Rev. Materials (2018)). It uses features computed with rascaline and uses the directional convex hull function from scikit-matter to make the figure.

.. image:: ../examples/gaas-map/images/thumb/sphx_glr_gaas-map_thumb.png
:alt: This example uses rascaline and metatensor to compute structural properties for the structures in a training for a ML model. These are then used with simple dimensionality reduction algorithms (implemented in sklearn and skmatter) to obtain a simplified description of the dataset, that is then visualized using chemiscope.

:alt: This example shows how to run a free-energy sampling calculation that combines path integral molecular dynamics to model nuclear quantum effects and metadynamics to accelerate sampling of the high-free-energy regions.

:alt: This example shows how to run a path integral molecular dynamics simulation using i-PI, analyze the output and visualize the trajectory in chemiscope. It uses LAMMPS as the driver to simulate the q-TIP4P/f water model.
