Oh yeah, there is. It's on page 102 of the HKL manual (Scenario 5: reindexing). Of course, if you are using HKL2000, you'd be confused regarding how to apply this "scenario". There is macro tab, of course, but I am not certain on how to make sure that the hkl matrix statement will be applied only to one of the sets. So the easiest way is to use the script from page 106 (of course, your space group is p21 and the hkl matrix should be "0 0 1 0 -1 0 1 0 0"). As I understand, another way is to trick denzo into choosing particular set of parameters. Something like reference zone in the index tab may give you a set of choices. If that works, you may be able to stay inside HKL2000 (it's not that you must, command line is much more flexible). HTH, Ed. --
