The goal of this project is to develop a suit of software programs that will nllow for the capture and analysis of multiple focal-plane, time-lapse movies. The acquisition of 3-dimensional time-lapse (4D) data sets involves the precise orchestration of a variety of hardware components including z-focus control motors, illumination shutters, digitizing video framegrabbers, serial I/O ports, etc. (Thomas et al. (1996) Science, 273, 603-607, Thomas dc White (1996) Sci. Comp. World, 24, 31-32). In the past, the IMR's 4D Live Cell Microscopy program has relied on an elaborate set of control macros for the freeware image processing application """"""""NlH-Image"""""""" to perform 4D data acquisition. While it deDmitely provided a usable system, the problem with this strategy was that NIH-Image macros are limited to 32 kb in size. The IMR's 4D acquisition macros quickly reached, and then exceeded this limit. Adding new features to the software or supporting new hardware components meant removing existing features or support. The goal of this subproject was to develop a non-dependent stand-alone Macintosh application for the acquisition of 4D data sets which would be unlimited in the amount of features that could be added and the number of hardware components which could be supported. It was also hoped that by optimizing the software specifically for 4D acquisition, that improvements in acquisition speed and ease-of-use would also be realized. The result of this project, the """"""""4D Grabber"""""""" application, is a significant step forward in 4D acquisition technology. Not only does the """"""""4D Grabber"""""""" application seamlessly coordinate the various hardware components of a 4D Live Cell microscopy workstation, but does so using easy to-understand graphic user interfaces in order to reduce the learning curve for the researcher wishing to perform these types of experiments in their own labs. The software supports 6 common digitizing framegrabber cards of both the Nubus and PCI slot configuration (including the ability to take advantage of on-card frame averaging, if present), and supports four different stage drive motors. Its modular code design makes adding support for additional hardware systems very straightforward. Significant increases in collection speed were also realized with the software's optimized design. An additional advantage of the """"""""4D Grabber"""""""" software is the ability to gather 4D data directly to compressed QuickTime movies. By taking advantage of this feature, it is possible to gather up to 15 times as many data points per given hard disk space than when using previous 4D collection systems. This collection mode also offers a very impressive savings in time since the lengthy data translation stage (which was formerly necessitated with all 4D data sets) can be completely eliminated. This application, like all the others in the IMR's 4D Imaging Suite, will be available free-of-charge to researchers all over the world via downloading from the Internet.
