Matrix Gemini Laboratory Information Management System (LIMS) includes versatile one-time configuration tools that allow the system to be configured without the use of custom programming and provide an audit trail each time a display screen for the system is updated or modified. If a screen is being altered, no one else can modify it until it goes live again. Each version is saved with a version number so the audit trail allows the possibility of returning to an earlier version if required. A visual workflow screen editor shows the screen in edit mode along with all the options and control properties associated with that screen. Screens can be linked together and information transferred between them without any programming. New screens can be created by copying and modifying existing screens from the screen library.
