PREPI is a molecular graphics program which can be used to EASILY produce and interactively
manipulate many different types of molecular representations (cartoons) as well as providing
quantative information on secondary structural topology. The program is not just limited to
proteins, but can also show cartoon representations of NUCLEIC ACIDS. In fact the program is
capable of displaying "ANY" object for which cartesian coordinates are available. The program
can input data from a wide range of data file formats (e.g. Broohaven PDB, Cambridge Databank,
SYBL, Z-MATRIX) including its own FREE FORMAT which allows for the construction of complex
objects such as Virus particles.
