Hi James 
LSQMAN can calculate the current RMSD between the 2 models (RMsd_calc mol1 
range1 mol2 range2 [Ltarget]) 
Be careful it renames the chain names

Objet: [ccp4bb] RMSD between unaligned structures 

Dear ccp4 tribe, 
this might have been asked before, but I haven't paid enough attention. 

I'd like to measure the RMSD between two models after molecular replacement. I 
can force the two models to overlap as much as possible within the symmetry and 
origin-shift constraints (using CSYMMATCH). But I don't want the program that 
compute RMSD to align the two structures. Can you suggest what I should use? 
And, perhaps, what keywords I should adopt? 

Many thanks, in advance.
