We also use the US portal. Can't speak to the solvent content as we never
had a value much over 70%.
As for the resolution range, I never saw any place to enter this
user-defined resolution of the structure.
As far as i know it comes from the record:
REMARK 200 RESOLUTION RANGE HIGH (A) : 1.200
which should be the high resolution used in refinement.
I suppose in an "additional remark" you could give the
optical resolution or the resolution of 90% complete at I/sig=2.
Or the title could be "The 2.2A resolution structure of protein x",
never mind that there were a few reflections used at 1.7A.

Phoebe, Jan, PDB,
is this something particular to the US portal of the PDB, or general?
We always use the European portal pdbe and have not had such "problems".

There have been other manipulations with user-input values. We could not input solvent
content 83% for 3cg8 (the real value!!!) as "being out of the allowed range".
The resulting value in the PDB is "NULL" not showing the actually interesting
feature of the structure.
I also noticed that the reported resolution values are nonsensically advertised
with three decimal positions after the point which is not the way we would put
it, is it?
Either fight it or live with it ...

I just noticed that the PDB has changed the stated resolution for one of my old
structures! It was refined against a very anisotropic data set that extended
to 2.2 in the best direction only. When depositing I called the resolution 2.5
as a rough average of resolution in all 3 directions, but now PDB is
advertising it as 2.2, which is misleading.
I'm afraid I may not have paid enough attention to the fine print on this issue - is the
PDB now automatically advertising the "resolution" of a structure as that of
the outermost flyspeck used in refinement, regardless of more cautious assertions by the
authors? If so, I object!
