We have created an OSF/Motif(TM) based GUI (graphical user interface) for the purpose of collecting, processing and interpreting area detector data. The design goal is to give the novice user the ability to collect and process data effectively while giving the experienced user all the control necessary to complete difficult tasks.

The interface has been designed to be as intuitive as possible. Many steps of data processing have been automated, relieving the user of such tasks. Visualization of all the steps of data processing has been implemented. Where possible, tables of results have been replaced with interactive graphical displays. Online help is provided through NCSA Mosaic and includes hyperlinked text and images.

A new direct-space Fourier transform indexing method has been introduced. Support for narrow-angle oscillations has been provided, while the traditional wide-angle oscillation methods have been retained. Algorithms for recursive, Fourier and spherical harmonic absorption corrections have also been added.
