Re: [ccp4bb] Could this be a complex crystal? or only RNA crystal? or micromolecular?

In this case, calculating Matthews coefficients / solvent fractions for different possible complexes will be helpful. http://www.ccp4.ac.uk/html/matthews_coef.html In the general case, without solving the structure I would dissolve the crystals and run them on an SDS-PAGE gel, then silver stain t

26 and 33 tells me you are over fitting your structure the spread is more than 5% If there is a ligand added and it really doesn't look like a good fit i would try work on it (remove it and look at alternatives) When you refine you may use NCS if you have (NCS in your structure) If there is a bett
