Hello Rafael--

  In order to exclude the possibility of HBDB causing your problem,
please make the following substitution in your script:

** change **

# hbdb - distance/angle bb hbond term

protocol.initHBDB()
potList.append( XplorPot('HBDB') )

** to **

# HBPot - knowledge-based hydrogen bond term
#
from hbPotTools import create_HBPot
hb = create_HBPot('hb')
hb.setScale(2.5)
potList.append( hb )

**

If the calculation continues to fail, please send output.txt generated
by

  xplor anneal.py >& output.txt

best regards--
Charles
