Hi Rana,
You probably have multiple options suggested to you. One is sftools
using the CALC command. If the subtraction includes a phase then sftools
can also do the calculation on the full structure factor.
Plain subtraction of amplitudes ensuring the result is >= 0
READ yourfile.mtz
CALC col fnew = col f1 col f2 - abs
WRITE yournewfile.mtz
Subtraction of structure factors
CALC (col fnew pnew) = (col f1 p1) (col f2 p1) -
f1, p1 etc are the column labels for amplitude and phase columns
respectively.
I recommend to run the program interactively and you can use CALC help
to get more help.

I was wondering if anyone knows what programme I need to use to
subtract the Fobs of two different crystals from each other.
