MOLMOL (paper at here) was a popular molecular viewer in the NMR society. It was developed in Kurt Wuthrich’s group and now available at SourceForge.net.

Here is an example using Pymol (demonstrated by 2.3.2) to illustrate MOLMOL’s cartoon style.

The commands are:

fetch 1p7t

hide /1p7t//B
hide ////HOH
bg_color white
set cartoon_highlight_color, yellow
set cartoon_rect_width, 0.03
set cartoon_rect_length, 1.7
set cartoon_discrete_colors, on
