[chimerax-users] Using ChimeraX Modeller interface

[Moradkhan, Tiglath A]

Hi

My name is Tiglath and I'm trying to use ChimerX Modeller interface to build a dimer model of a protein I'm currently studying. I first tried to run a BLASP search to find templates but it seems that in ChimeraX, this works differently than in Chimera. In the user guide it says that if the query is a sequence whose structure hasn't been determined, then it's not necessary to specify particular chains. However, when I try running the BLAST search it doesn't do anything. It seems that it is necessary to specify a chain number. But how is this possible if I don't know the template for the target sequence? Am I missing something? Also, I'm a little bit unsure how the Modeller interface works for building dimers.

I would be very glad for your help.

Thank you

Tiglath
