how to define ribbons color?

[albert]

Hello,

I am trying to define a muti-chain PDB with specified color for ribbons. However, I cannot find this option in SAMSON.
Does any body know to do it?

Thanks a lot
Albert

Hi @albert ,

There are several options for the colorization of structures or visual models (Ribbons is a visual model) based on chains:

1. The colorization using color schemes. First, select the Ribbons visual model in the Document view that you would like to colorize. Then:

• Biology > Colorize > Chain ID or Chain (illustrative) (i.e. in the style of D.S.Goodsell)
  
  You can also choose "Custom..." from the list and specify the color palette.

2. The colorization with constant colors per chain.

• Choose a chain in the Document view.
• Set the color using Visualization > Colorize.
