Re: [modeller_usage] query about coil region!!

There is a way to enforce coil formation: manually modify the reference alignment so that the query is not aligned to the reference in the area of interest. Why do you want to do this?

If the model is aligned with a template, you will get spatial restraints
that aim to constrain the model to look like the template. So if your
template is a helix, and you try to add a strand secondary structure
restraint, the two will conflict. So secondary structure restraints only
really work in regions of low sequence similarity.

There is no "coil" secondary structure restraint, because "coil" is
essentially the lack of any defined secondary structure. It's probably
what you'll get by default in unaligned regions. There is no restraint
that says "please don't form a helix or strand".
