how to find out structure of protein-folding?

[Arne Mueller]

Hello,

I want to produce some images with molscript, so I need to know wich residues
of a protein are involved in helix, turn or sheet. Most pdb-files don't have
any direct information about this, so I need a tool that finds out where these
structures are. 

If you know souch a software, plase send me a mail.

thanks,


	Arne
