[modeller_usage] dihedral phi psi restraint



Hi,
in a Modeller-generated .rsr file, I have lines like this one:

R    9   3   4  25   8  18   2   5   4   4     7     9    10    12   9
10    12    14       0.1295    0.3250    0.5455   -1.0908   -0.7138
-1.1903    2.5360   -2.3   3880 387    2.5656    0.0908    0.1065
0.2059    0.2164    0.5271    0.3072   -0.2541     3880  -0.4199
-0.6670

I suppose it's a restraint on phi-psi angles, but I cant find a
description for Feature "4" (third number in first line) in the Modeller
documentation (http://salilab.org/modeller/manual/node447.html). 

Moreover, why are there two features for this restraint (numb_feat=2)
and what does Modal2 = 5 stand for?
Are restraints of this type (i.e. Group=25, dihedral) always generated
by default (Modeller version >= 9.5)?

Thanks a lot in advance
