[ccp4bb]: I to F's

[Ronado Nagem <nagem@lnls.br>]

Dear CCP4 users;

I would like to know if someone could tell me what is the mathematical algorithmn

that is implemented in SCALEPACK2MTZ, when it converts I and sigmaI to F,sigmaF's,

Imean and sigmaImean, and also in TRUNCATE when it calculates DANO, sigmaDANO from

F(+) and F(-).


Basically, I would like to know the formulas used in such programs for converting

a sca file with anomalous signal to a mtz.


Thanks you all for helping.


Ronaldo Nagem.
