<TITLE>Question about occupancy refinement of riding hydrogens</TITLE>
</HEAD>
<BODY>
<!-- Converted from text/rtf format -->
<P><FONT FACE="Arial">I just noticed that occupancies of riding hydrogens are being refined by default, in fact I am unable to turn this feature off (CCI-APPs from Jan-8). I was just (very naively) wondering what is the rationale behind this? The B-factor refinement for riding hydrogens is already enabled and should take care of this or not? It looks a bit odd to have hydrogens with occupancy 0.9 sitting on a carbon with occupancy 1.0 at 2.0 A resolution.</FONT></P>
