Subject: cpkpdb announcement


cpkpdb - a simple molecular visualisation program.

We would like to announce the free availability of the
availability of cpkpdb, a simple program intended 
for generating CPK images of large molecular systems. 

The rationale for writing this program is that 
conventional molecular graphics codes, which utilise polygon
based display modes which become increasingly slow
as the size of the molecule grows. By employing a pixel
based (stamping) method the time required by the cpkpdb
code is approximately independent of the molecule size.   

In particular we have found it useful for displaying CPK
images of virus particles which typically outstrip the
capability of most grahics codes. There is no limit on the 
number of atoms/residues imposed by the program.

The program has been compiled/tested on SGI platforms 
only and is available in two forms

(a) compiled on a R4K system under irix5.3, tested
	under irix 5.3 on R3K and R4K systems.

(b) compiled on an R10K system under irix6.2,
	tested under this system and on an R5K under irix6.3 

A short manual file describing the programs capabilites
is also included.

To obtain the program simply send an e-mail request to

	mforster@nibsc.ac.uk

and I will send back the WWW address at which the program
can be located. I'll also be happy to receive suggestions
for new features and improvements.

Usual legalese concerning use at your own risk also applies here.
