Well - I usually use the COOT ncs map generation first.
You place waters into good peaks in the 3 fold averaged map -say it is A
B C - check that there are reasonable peaks in the other rotated maps -
then once the waters are generated for A, fit those coordinates A to B
and save them, then A to C and save.
Youneed to change the water chain ID for the B set and C set ..
