Hi people,
	I have written a program that allows one (using a SGI irix 4.0.5)
to display the contents of a PDB file (the molecular model actually).
	The program will create at startup 3 standard objects which can be 
interactively toggled ( F1 = C-alphas, F2=backbones and 
F3=all-PROTEIN-atoms-in-PDB).
	This program also allows the user to create a secondary window
to display the Ramachandran plot of the molecule being viewed. Actually
the plot starts empty and a pop-up menu is available in the window that 
allows the user to chose between the plot background (either theoric 
areas or procheck statistics).
	Besides allowing the user to rotate-translate-scale-slab-etc with 
some complicated mouse button combinations it is also possible to pick
atoms (there is a four [4] atom buffer; last four picked atoms) and to do 
measures with them (e.g. distance, dihedral, neighbours and 
Hbonds [irgh nasty, it is not really H-bonds] ).
	Things that are hard to do on most mol/graph packages: when looking at
the C-alpha trace you can pick an atom, press "a" on the keyboard and 
you're presented with a sphere of atoms within 10 A of the picked atom. 
Also after picking an atom you press "s" for a sidechain, "r" for the 
residue, "o" for the neighbours and lots more.
	The program [173 Kbytes G-ziped] is freely available in the
WWW:
http://dart.ifqsc.sc.usp.br:8080/usuarios/zac/progs.html
The pseudo-man page is in this document.
	All you have to do is g-unzip the file pdbv.gz make it an executable
(chmod a+x pdbv) and place it somewhere in the PATH.
	Start it by typing at the unix prompt: pdbv -f model.pdb

	Any comments, please feel free to send me e-mail.
	Please do NOT send bug reports because there are to many.
