<BODY>
<FONT FACE="Calibri, Verdana, Helvetica, Arial"><SPAN STYLE='font-size:11pt'>I’m trying to refine a 3.5 anstrom structure with one TLS and one ADP per chain, but I keep getting the error message:<BR>
<BR>
“Sorry: Selections for group B-factor refinement are given, but no refinement requested.”<BR>
<BR>
The parameters file is listed below. Any suggestions? <BR>
<BR>
Best regards and happy New Year,<BR>
