[Chimera-users] Superimpose map with fitted atoms

Hi Luca,
Maybe “matrixcopy”  to apply the transformation of one model to another, e.g.  if map #3 with fit atoms #4 was matched onto some other map, then bring atoms along with:

matrixcopy #3 #4


The part I’m not sure about is whether the fit-atoms model #4 would need to be in the same coordinate system as #3 (previously saved relative to #3 and then read back in). 

I hope this helps,
