Hi Matthieu,

Hi, omit-map works fine for me but I have two items on my wish list.

1) Can we compute a difference-map (mFo-DFc map instead of mFo-DFc map) ?

I have not tried this, but I think that if we set the occupancies of all the atoms in an OMIT region to 0.0, then if we calculate a difference map mFo-DFc then this will look almost exactly like the mFo-DFc map because Fc leads to no density in the OMIT region. Won't that be so? Let me know if I have missed something in this!

2) Is it possible to play with the size of the area omitted around the selection ?

Yes, you can do this with the keyword: offset_boundary=1.0 All the best, Tom T

Thanks again.

A true phenix-fan
