However, since that I have no hydrogen atoms in the pdb structure, I assume that the angle theta (donor-hydrogen-acceptor) cannot be used by Chimera as an angle criteria, and so the psi or phi angles might be used instead. Which angle is actually used in the relaxed parameters? And most important, what is the default value of that angle (angle minus relaxing value)?</div><div class="gmail_default" style="font-family:verdana,sans-serif"><br></div><div class="gmail_default" style="font-family:verdana,sans-serif">Thanks in advance for your help.</div><div class="gmail_default" style="font-family:verdana,sans-serif"><br></div><div class="gmail_default" style="font-family:verdana,sans-serif">Best regards,</div><div class="gmail_default" style="font-family:verdana,sans-serif"><br></div><div class="gmail_default" style><br></div><div><div class="gmail_signature"><div dir="ltr"><div><div><font face="verdana, sans-serif"><b>Andrés Felipe Vásquez J., <i>BSc, MSc.</i></b><br>Grupo de Fisiología Molecular</font></div><div><font face="verdana, sans-serif">Subdirección de Investigación Científica y Tecnológica</font></div><div><font face="verdana, sans-serif">Dirección de Investigación en Salud Pública<br>Instituto Nacional de Salud<br>Avenida calle 26 No. 51-20 - Zona 6 CAN</font></div><div><font face="verdana, sans-serif">+57 (1) 2207700 ext. 1419</font></div><div><font face="verdana, sans-serif">Bogotá, D.C., Colombia<span style="font-size:small"> </span></font><br></div></div></div></div></div>
