Even if you can't see them, it may be worthwhile investigating with Auspex (Parkhurst, Thorn, Winter & Waterman - sorry, I can't remember the reference off-hand). There's an easy to use webserver somewhere that runs it... Harry -- Dr Harry Powell > On 25 Mar 2019, at 09:03,

Hmm - I find maprot extremely confusing, but remember a wrkmap does not use any symmetry so maybe that is why some is lost. I would have done this, but I havent tested it. And the documentation is SERIOUSLY confusing!! Do I understand you want to ADD the density for mol B to that of Mol A

As I understand helical assembly, the data some time is anisotropic (any one or two a*,b* or c* has more diffraction than other), which may be responsible for your high Rfactors. You can crop the data to the resolution using softwares. Regards Sharan On Mon, Mar 25, 2019, 8:17 AM Andreas Förster

Hello, I rather think the model has a problem. Are there large domains which are invisible in the structure ? Is it possible that the data are twinned ? Did you use TLS refinement to account for anisotropy ? Just cutting the resolution will probably not help, unless
