Development of software for visualization, analysis, reduction and simulation of x-ray experimental work has been a major output from the APS. This page describes a number of projects, some mature and others in initial stages that are being actively developed by scientists with the X-ray Science Division, often aided by software engineers within the AES Software Services Group and sometimes in collaboration with other parts of Argonne or external laboratories.
