I have modelled a protein using secondary structure restrained script...
The model seems to be perfectly fine .. but one portion of the model is
converted into a helix which has to be a loop according to the template
.. how can I force that region to be a loop ???
You can't *force* it, but if you unalign the target and template in this
region, loop/coil is the most likely secondary structure you'll end up
with. See
