[modeller_usage] Loop refinement: setting the right anchors in multichain models

[Jérôme Hénin <jhenin@imm.cnrs.fr>]

Hi everyone,

I am trying to do loop refinement on a multi-chain protein. My problem
is that Modeller tries to anchor C-ter loops to the N-ter of the next
chain, yielding unrealistic starting configurations, and making the
whole refinement fail.

How can I instruct Modeller that the C-ter and the following N-ter
"loops" are to be modeled separately?

Thanks,
Jerome
