Hi CCP4bb, I would like to ask about "envelope phasing" - specifically with SAXS data.
There are papers (1) and tutorials (2) describing how this might be done, but I have also found comments on the ccp4bb, such as this one (http://www.proteincrystallography.org/ccp4bb/message11690.html) which are somewhat less optimistic. I get the impression from my reading around that SAXS envelope phasing is somewhat difficult to do unless you have some NCS you can use to help the phase extension process. Does anybody have any opinions/evidence/examples/anecdotes/tips about how SAXS envelope phasing can be done successfully?
