.. _chemiscope: chemiscope ========== 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 `_. .. grid:: 1 2 2 3 :gutter: 1 1 2 3 .. grid-item:: .. card:: Generalized Convex Hull construction for the polymorphs of ROY :link: ../examples/roy-gch/roy-gch :link-type: doc :text-align: center :shadow: md .. image:: ../examples/roy-gch/images/thumb/sphx_glr_roy-gch_thumb.png :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. :class: gallery-img .. grid-item:: .. card:: PCA/PCovR Visualization for the rattled GaAs training dataset :link: ../examples/gaas-map/gaas-map :link-type: doc :text-align: center :shadow: md .. 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. :class: gallery-img .. grid-item:: .. card:: Path integral metadynamics :link: ../examples/pi-metad/pi-metad :link-type: doc :text-align: center :shadow: md .. image:: ../examples/pi-metad/images/thumb/sphx_glr_pi-metad_thumb.png :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. :class: gallery-img .. grid-item:: .. card:: Path integral molecular dynamics :link: ../examples/path-integrals/path-integrals :link-type: doc :text-align: center :shadow: md .. image:: ../examples/path-integrals/images/thumb/sphx_glr_path-integrals_thumb.png :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. :class: gallery-img
