In the first cycle DMMULTI calculates solvent masks for the two crystals. Does it continously improve these masks or stick to the initial one ?
If it acts like DM, then it updates it (using default options). But on the other hand, DMMULTI doesn't appear to to support SOLMASK UPDATE keywords. Kevin can speak authoritatively about this, or you could compare SOLIN and SOLOUT and see if they're different.
Since DMMULTI does not apply gamma-perturbation (solvent flipping) should I use it to the highest common resolution (5A) only and continue with DM/PARROT to 4A ?
Your mileage may vary, but a few years back I compared solvent flattening and gamma corrected solvent flipping in PHASES on some low resolution data and got roughly comparable results (stock solvent flattening was slightly better for this data, though).
Thank you for your time and advice, Peter
