Density E. IFC

Energy Density of the IFC - The sum of Energies (calculated according to the table of energy values for each contact type) for the contacts established within a given sphere, among the residues belonging to two different chains facing each other, is calculated and then divided by the volume of the sphere.

Placing the cursor above this element: pop-up area will show the summary of "Density E. IFC" data for this particular amino acid.
Left mouse click: no action
Right mouse click: on any of the "Density E. IFC" will generate following menu and actions:

Figure below is showing specific position for the row with the "Energy Density of IFC" data in JPD presentation.

A) A user may select either Ca or Last Heavy Atom (LHA) in the side chain as a center of the sphere for calculating "Density E. IFC"

B) A user may select among 5 possible radius values for the sphere:

C) STING it "Density E. IFC.": This option generates structural presentation with color coding of the amino acids corresponding to the JPD row "Density E. IFC." color coding. The area of interface between the two chains is where the colors are going to be different from the rest of the protein. Amino acids are presented in CPK rendering.
