Hello Xplorers!

I am currently refining a large protein structure and would like to
exclude several aa side chains from the refinement and xFo-yFc map
making procedure.  Is it best to:

1.	Physically remove the atoms from the input pdb file

2.	Use the 'delete' statement as follows:

	selection = ( segid "sega" and resid 113)
	selection = ( segid "sega" and resid 114)

3.	Set the atoms occupancy to '0'
4. 	None of the above.  Please suggest...

Thank you for any input.  It is always appreciated.
