Interesting. I've also noticed that lines (such as those shown below) are missing from the logfiles whether I select *individual_sites_real_space or not.

|-LOCKIT real space refinement (target=simple): start-------------------------|
| r_work=0.2098 r_free=0.2283 rmsd bonds=0.004 angles= 1.03                   |
|-----------------------------------------------------------------------------|


|-LOCKIT real space refinement (target=simple): end---------------------------|
| r_work=0.2203 r_free=0.2521 rmsd bonds=0.004 angles= 0.74                   |
|-----------------------------------------------------------------------------|

Could it be that the global *individual_sites_real_space strategy was actually not performed in either case? I would be glad to send you the logfiles off list, if that would be more helpful.
Thank you,

Hi,

yes, this is exactly it. Sorry, I keep promising to clean this
naming/conception mess one day. Hopefully (thanks Herb), this day is
approaching fast!

We noticed that in some of our refinements, real space refinement was

I tried to opt out of real space refinement as follows:
" refine {
    strategy = *individual_sites individual_sites_real_space rigid_body \
               *individual_adp group_adp *tls *occupancies group_anomalous
..."
however, the R-free is identical whether we select real space refinement or
not, and the logfile shows

and  suggesting that real space refinement was performed.
That's the rotamer fitting - technically, it's an independent step
(fix_rotamers=True)  The individual_sites_real_space strategy only
performs global real-space refinement.
