Day 1 – Monday, June 19

Beginning of the Users program

  • 10:30 am – 12:30pm: Arrival
  • 12:30 pm – 2:00 pm: Lunch
  • 2:00 pm – 3:30 pm: Welcome – Introduction and installation of SAMSON - Show (all) - Hide (all) - View tutorial

    We introduce the Users program of the SAMSON School and SAMSON, the software platform for computational nanoscience. We highlight the need for an integrated platform able to combine diverse domains of nanoscience, which led to SAMSON's open architecture and the creation of the SAMSON Connect online platform. We introduce SAMSON Connect, the online platform used to distribute SAMSON and SAMSON Elements, the modules for SAMSON, and we install SAMSON and default SAMSON Elements.

We explain how to modify preferences and control the camera.

  • 5:00 pm – 6:00 pm: Basics II – Editors, apps, context menus, groups and conformations - Show (all) - Hide (all)

    We demonstrate essential editors to select, create and modify basic molecular structures. We explore the concept of SAMSON apps and demonstrate a simple app to download PDB models from the Protein Data Bank. We explore context menus and groups, and give an overview of interactive simulation in SAMSON. Finally, we introduce conformation nodes in SAMSON to store and retrieve molecular conformations.

Day 2 – Tuesday, June 20

  • 7:30 am – 8:30 am: Breakfast
  • 8:30 am – 10:00 am: Producing publication-quality images and animations - Show (all) - Hide (all) - View tutorial

    We explore how SAMSON can be used to generate publication-quality images and animations, thanks to visual models and color schemes, and fine control of rendering options and effects, including interactive ambient occlusion, depth-of-field rendering, silhouettes, anti-aliasing, multisampling, etc. We show how to setup SAMSON to capture snapshots of the viewport.

  • 10:30 am – 11:30 am: Selecting and modeling with the Node Specification Language - Show (all) - Hide (all)

    We describe SAMSON's powerful Node Specification Language (NSL), and demonstrate how it can be used to perform advanced selections and modeling tasks, such as finding a binding site in a protein, building a nanopore, etc.

  • 11:30 am – 12:30 pm: Simulating small molecules, graphene and proteins - Show (all) - Hide (all) - View tutorial

    We demonstrate how SAMSON can be used to perform interactive simulation of various systems, including small molecules with the Universal Force Field (UFF), graphene and nanotubes with the Brenner force field, and proteins with GROMACS force fields. We show how interactive minimization helps produce realistic structures. We discuss the choice of state updaters.
