Academic software

The Higher Education National Software Archive (HENSA) is on the www, the part for micro computers is at http://micros.hensa.ac.uk with sections for PCs, Macs, and Acorn. You can find versions of the popular protein display package RASMOL, a public domain ray tracing package POVray, and PGPLOT a portable graphics package written in Fortran77 (for details see http://astro.caltech.edu/~tjp/pgplot/). The ISIS supported analysis software, GENIE, now uses PGPLOT for its graphics. (http://www.ISIS.rl.ac.uk/OpenGENIE). ORNL, the originators of ORTEP, the thermal ellipsoid drawing program, have added an interface to PGPLOT to simplify porting ORTEP across to new computers. (http://www.ornl.gov/ortep/ortep.html). D.S.Sivia has written a set of routines PGXTAL, for 3D plotting structures and density maps with PGPLOT (http://www.isis.rl.ac.uk/dataanalysis/dsplot).
