and the General Particle Tracer (GPT) code

GPTwin User Interface: The GPTwin Graphical User Interface is an all integrated simulation platform on Microsoft Windows machines. GPTwin has an inputifle editor with on-line help to create one or more files describing the set-up to be simulated. A separate file is typically used to specify variables to scan, hierarchical data-analysis and inport/export utilities. Batch files can be used to run GPT and automate pre- and postprocessing tasks. Special wizards are available to assist the advanced user with the creation of custom beam-line components and data-analysis programs.

GPTwin Plotting: GPTwin is capable of plotting GPT simulation results in a variety of formats: Scatterplots, lineplots, histograms and color-density plots are all created instantly from adaptable template files. The hierarchical binary GDF format used by GPT and all utility programs allows files of several gigabytes to be opened and plotted efficiently. Additional views of the same data with different projections can be plotted simultaneously. When output is requested at different positions or times these views are always kept synchronized. All plots can be printed, exported to Windows (Enhanced) Metafiles and copied to the clipboard.

Note to Linux and Max OS X users: There is no GPTwin equivalent for the Linux and Mac OS X releases of GPT. On these platforms only the command-line interface is available.
