# Data Analysis and Visualization Environment
## DAVE
## Version 2.x

DAVE is an integrated environment for the reduction, visualization and analysis of inelastic neutron scattering data. It is built using IDL (Interactive Data Language) from Research Systems, Inc. * which is a cross-platform application development tool with built-in graphics. All efforts have been made to ensure that DAVE is supported on Linux, Windows and MacOS X. It is available at no cost to users in two forms. The first is as a binary executable with an embedded IDL runtime license which can be used by anyone running on any of the three supported operating systems. In addition, for those who have an IDL development license, the complete source code for DAVE is also available.

The main objective of DAVE is to provide a user friendly tool for scientists involved in neutron scattering research to quickly reduce, visualize and interpret their data. Currently, much progress has been made towards achieving this goal even though a lot still remains to be done. Support for several neutron scattering spectrometers at NCNR and PSI is included.
