CCP4ers, a log file from Refmac_5.7.0027 presents me with this line:
<fromLog> Problem with the ADP of the atom N A 3 ADP is non-positive -1.7740907E+35 </fromLog> I did not explicitely refine ADPs or TLS. Should I modify my model when I encounter such a message? If yes, does the message refer to a specific atom, such as atom N of residue 3 in chain A? I should note that that atom is omitted from my model due to lack of electron density/disorder. Many thanks in advance, Wolfram Tempel
