There is a lot of confusion about this!
You can call it R3:H ( indexed with a=b and gamma = 120)
This is also called H 3 in the PDB deposition and the CCP4 symmetry
libraries.
(But for the CCP4 library - it checks the axes and angles to decide
whether this is using the H ( or hexagonal) convent
Coot (and SSM) should give matrix - euler and polar angles! Paul? Eugene?
But if you do the superposition with lsqkab (superpose molecules - match
residues) then that gives all 3 ways.
Or use ROTMAT which converts everything to everything else.. ( rather
clumsy though..)

I have obtained some promising X-tals in 2M Ammonium Nitrate. I am
now looking for freezing conditions. Has anybody had experience in
successfully freezing X-tals under similar conditions ? What was the
best cryo-protectant and which concentration was optimal ?

Is this a SHELX data set where the FreeR is flagged as -1?
There seems to be a variety of methods ..
But if you read in the FreeR flag from SHELX and ask to have a FreeRflag

will output the SHELX value

Yes there is a way to do something anyway.
Is your metal only linked to protein or are there extra atoms as part of
the metal?
If there is protein lins you need to make a LINK record in your PDB and
provide a dictionary description of your expected geometry.
If you have more details I can b

I am often receiving only responses to the original queries posted on CCP4BB
but not the original

Has anyone else noticed the same?

1) Rfree in the first cycle seem to be more apparent than actual. You
need to check you free reflection conversion. It may turn out that you
have more reflections for free than for working R.
2) You may need to use tighter restraints. For example by changing
weight matrix value to smaller numb
