[phenixbb] Re: adding together

      Thanks Tom!

And if I wanted to square them first?  This is for a diffuse scatter 
calculation, BTW.  Need phased and unphased sums.

Hi James,
Sounds like the chat did not do well on this one!
You could try:
phenix.average_map_coeffs map_coeffs_1.mtz map_coeffs_2.mtz
All the best,
Tom

Greetings Phenix developers!
I have what I hope is a quick question.  I'm trying to add a stack of
    phased structure factors together.  Specifically from separate
    runs of
    phenix.fmodel.  Normally, I'd use sftools for this, but the
    distributed
    version has a size limitation.  According to Tom's phenix chatbot,
    I can
    use phenix.maps for adding two sets of structure factors together,
    but
    it seems to only want to combine an mtz with a pdb. There is
    iotbx.reflection_file_editor, but it only works from the GUI (and
    I want
    to add 1000 mtz files together). phenix.xmanip looks promising
    too, but
    again, seems to want a pdb and an mtz.  Is there a recommended way
    to do
    this?
I've already asked this on CCP4BB, but I wanted to get the Phenix
    take
    on these kinds of manipulations.
Thank you,
