Dear Tim

In principle if a user defines freer flag then refmac knows about that (unless freer flag is 0 then refmac assumes that it is default). In this case (if freer defined by user) then it is not altered.

Dear Pavel, dear Garib,

how do you figure out automatically the correct flag? (I hope both
phenix and refmac will allow to manual overwrite the software's decision)

Cheers,
Tim

Hi,

It would be nice if default setting was the same in different
suites.


it's a nice idea of course, but I feel it is impractical as it
would require changing a lot of software, both modern and legacy.
However, given array of flags it is algorithmically trivial to
figure out what is test and work flags. That's what phenix.refine
have been doing since its beginning (2005). And my understanding
is that Refmac does this too. As always, there are corner cases
here, but it's better than nothing. Plus, programs (at least
phenix.refine, can't speak for others) tell which flag was
actually used, and they provide option to define the flag value to
use.
