# What is Molby?

Molby is an application to visualize and build molecular models interactively through 3D display. It provides the following capability:

- Viewing molecular models in either ball-and-stick or "line" display.
- Interactive modification of molecular models by mouse operation.
- Optimization of the structure by molecular mechanics calculation. Also capable is the molecular dynamics calculation.
- Viewing and editing atomic coordinates, molecular mechanics atom typs, and other parameters in tables.
- Importing and exporting structure/coordinate data for other program packages such as Gaussian, GAMESS, NAMD and SHELX.
- Embedded Ruby interpreter for automated processing of molecular models.
