GRIP-71(ID:7264/gri007)Second (1971) version of GRIP Related languages
References: The GRIP-75 system grew out of the GRIP-71 system of Bill Wright (1971, 1972). GRIP stands for Graphical Interaction with Proteins. The GRIP-75 system was designed and built by E.G. Britton, J.S. Lipscomb, M.E. Pique, W.V. Wright and F. P. Brooks, Jr. Brooks' laboratory is interested in human factors and the man-machine interface and scientists who came to Chapel Hill to use the system were observed while using it (Brooks, 1977). The system had very convenient analog input devices, stereo with a shuttered viewing device, Ramachandran plots, and used the Hermans and McQueen (1974) idealization algorithm. The GRIP-75 system was written almost entirely in PL/I. The hardware consisted of a Vector General model 3 display, a PDP-11/45 minicomputer and an IBM 360 model 75 mainframe. Numerous protein structures have been solved using the system, include the snake venom alpha-neurotoxin (Tsernoglou, Petsko, McQueen, and Hermans, 1977), Cu-Zn superoxide dismutase (Tainer, Getzoff, Beem, Richardson and Richardson, 1982), and transfer RNA (Sussman, Holbrook, Warrant, Church and Kim, 1978). Tom Williams (of UNC) has developed a ridge-line program called GRINCH (Williams, 1982) for fitting electron density that is used by Duncan McRee's XTALVIEW (McRee, 1993). |
