[ccp4bb] Which version CCP4 output DFc colume in SIGMAA?

[Hailiang Zhang]

Hi,

I remember the SIGMAA utility in some version of CCP4 can output DFC
colume in the mtz file. If somebody see this colume in you SIGMAA mtz
file, could you let me know which version CCP4 you are using? THanks!

Best Regards, Hailiang
