Fellow crystallographers,

I am helping a college with a structure and we've run into a bit of a
jam.  She has a 2.5 ang sel-met dataset, solved, and a 1.8 ang native
dataset.  We would like to extend the phase solution from the anomalous
data to the native data.  Unfortunately I have not been able to figure
out how to do this using CCP4.  The phase solution was calculated using
PHENIX, which I have no real experience with yet, having worked with
SHELX, CNS, and CCP4 in the past.  Can anyone point out the programs, if
any, in CCP4 (v6.1.3) to extend the phases from the 2.5 anomalous to the
1.8 native data?

Thanks,
Stuart Endo-Streeter
