Menu:

This command is mainly useful for macros. There is no menu entry.

AveragePos , RMSF, RMSD , Sup

Required:

The AddPos command adds the positions of the selected atoms to an internal table. Using this table, you can then calculate average atom positions and root mean square fluctiations. A detailed description of the procedure can be found at the AveragePos and RMSF commands.

Example 1:

AddPosAtom Obj 1

Add the positions of the atoms in object 1 to an internal per-atom table for average and RMSF calculation.

Example 2:

AddPosAtom CA Obj 1

As above, but consider only the Calpha atoms.

Example 3:

AddPosRes Obj 2

Add the positions of the geometric centers of the residues in object 2 to an internal per-atom table for average and RMSF calculation, duplicating the per-residue result for each atom.
