In case it helps… After you've done unrestrained refinement, you can use
prosmart to generate external self-restraints to the current conformation
(using the -self_restrain keyword). This is flexible - you can specify residue
ranges, and it works for protein, ligand, DNA/RNA, waters, etc. These

Dear Yuri,
at 1.18A resolution you can also refine using shelxl. It's basically
your choice on a per-atom-basis what properties you wish to restrain
and which to leave unrestrained.
With L.S. refinement and given enough RAM it can print esds of your
Hi Yuri,
If you have access to mogul you can get an understanding of what your geometry
should be based on the small molecule database. Of course not everything is
well represented so if your ligand is unusual this will flag up in lower
statistical significance.
Mogul will allow you to
I second Tim Gruene's suggestion of SHELXL; it's perfect for this.
However, there is a steep learning curve, so I strongly urge you to
pay close attention to the SHELXL (and SHELXPRO) manuals.

You can do unrestrained refinement in refmac, at your resolution it may
be OK. If you want to keep protein restrained, you can either use
harmonic restraints or come up with a special cif-file for your ligand
with large esd targets. There is no direct way to tell refmac to
exclude specific
