well yes - essentially you first superimpose lobe 1a to lobe1b , then lobe 2a to the superimposed copy lob2b-superposed. The theta phi *chi or omega *angle for the second superstition tells you how rotation there is between the open and closed form. There are various ways to do this - lsqkab in CCP4I - GESAMT in CCP4I2 (but not sure how easy it is to select a lobe..) Probably possible in COOT but the log file isnt very helpful.. More detailed advice if needed.. Eleanor
