RANTAN in CCP4 is for the determinaion of heavy atoms in protein
structures. You don't need the number of sites. RANTAN works out the
phases for the large E-values and the Emap should show the possible
sites if the E-values are calculated from anomalous differences or FM
output by REVISE in CCP4. ACORN in CCP4 is another way to try to
determine heavy atoms.

Best wishes.
