Threading sequence onto template with missing residues
Hello,
I have a template with lots of missing residues. I want to thread my target sequence onto the aligned parts of the template that are present without moving my target structure in these areas.
In my target sequence, I also wish to know how to skip modeling the missing parts altogether, thus making the job a mere threading of aligned unknown regions onto the known ones.
Is there a simple way to accomplish my task without doing too much manual alignment and residue listing? Please do post a code snippet if you can.
Thanks a lot.

This is the default Modeller behavior when constructing the initial model (*.ini file).

To do that, override automodel.select_atoms as per https://salilab.org/modeller/9.24/manual/node23.html and select only the aligned residues. If you want to automate it, look at model.get_insertions() at https://salilab.org/modeller/9.24/manual/node176.html
