Dear Modellers,
I saw that someone already encoutered that error in the modeller digest .. but unfortunately there was no answer (or just to use the "output='long'" command what I did without any answer) I try to model a protein structure, using 4 different templates with about 30% of sequence identity with the target.
Modeller always send me the same error message: r_dista_644W> Two basis restraints have means too far apart:
ICSR MEAN1 MEAN2 STDEV1 STDEV2 R.VIOL1 R.VIOL2 NEW_SD1 NEW_SD2
stdevs__397E> STDEV < 0: -0.1509
Set to 1E-5.
recover____E> ERROR_STATUS >= STOP_ON_ERROR: 1 1
Could someone explain me the meaning of this and how to fix it?
thanks a lot for your help.

This error message is usually encountered when two residues in the target sequence are aligned with two or more template distances that are very different, so that the corresponding combined restraint cannot be reproduced accurately by a cubic spline. Almost invariably, this error occurs when there is an error in the alignment (ie, one template 'says' a particular target distance should be close to 10A and the other template says it should be 20A). But in your case, it seems something else may be wrong, because stdev is less than 0. Would you please modify file $MODINSTALL6v2/modlib/messages.lib from
M 644 3 1 Two basis restraints have means too far apart: ICSR MEAN1 MEAN2 STDEV1 STDEV2 R.VIOL1 R.VIOL2 NEW_SD1 NEW_SD2
To (add @S1 in the fourth line, and keep a blank line after the @S1):
M 644 3 1 Two basis restraints have means too far apart: ICSR MEAN1 MEAN2 STDEV1 STDEV2 R.VIOL1 R.VIOL2 NEW_SD1 NEW_SD2 @S1
And email me the log file output.
I know the message should be more informative and it should print what the violating distance is, and some day we will get there ;-)
I hope this helps.
Best, Andrej
