OK. I can see a bit clearer now :) Yet which leads me to another question.
About the group selection analysis below: Select group for analysis
Group 0 ( System) has 2616 elements
Group 1 ( Protein) has 2470 elements
Group 2 ( Protein-H) has 2470 elements
Group 3 ( C-alpha) has 314 elements
Group 4 ( Backbone) has 934 elements
Group 5 ( MainChain) has 1246 elementsGroup 6 ( MainChain+Cb) has 1540
elementsGroup 7 ( MainChain+H) has 1246 elements
Group 8 ( SideChain) has 1224 elements
Group 9 ( SideChain-H) has 1224 elements
Group 10 ( Prot-Masses) has 2470 elements
Group 11 ( non-Protein) has 146 elements
Group 12 ( Ion) has 2 elements
Group 13 ( CL) has 2 elements
Group 14 ( Water) has 144 elements
Group 15 ( SOL) has 144 elements
Group 16 ( non-Water) has 2472 elements
Group 17 ( Water_and_ions) has 146 elements What are those really? I don't have
biology background really. All I know is that Protein (Secondary structure) has
one or more chains and in it hasamino acids. And the protein consists of alpha
helix and beta sheets. Basically my project is to plot contact map on the
selected chain ( consisting alpha helix & beta sheets) of a protein.I'm just a
bit confused what are those groups for? I mean I don't really need those. I
just need to plot on a chain. Many thanks,Suhaila> Date: Mon, 19 Mar 2012
