I am confused.  RasMol for Windows, at least (and I believe therefore all 
current versions of the program) is able to "restrict" presentation of 
different portions of a molecule using different arguments to the 
"restrict" and "select" commands.  e.g. to display aa 120 - 345 only in a 
protein of 600 aa, use the command

restrict 1-119 or 346-600

This will leave only the  desired residues on the screen.

To display as "ribbon" format, use the DISPLAY -> RIBBON menu items.

To show aa 125, 300 and 380 only as spacefill in the ribbon, use:

select 125, 300, 380
and then do DISPLAY -> SPACEFILL in the menu.


It may be possible to use SELECT command with a structural argument, e.g.

select helix

or

select 120 - 350 and helix

and then modify the display parameters by the menu.

Do you have the manual for RASMOL 2.5?  I believe a .PS and .txt version 
is available at the same location as the program.
