[phenixbb] MR_Rosetta and dimer of heterodimer

Hi everybody, I'm trying to phase a dimer of a heterodimer of a large, ~700aa, and small, ~150aa, component. The only good search model according to HHpred covers the first 500aa of the large component. So I am wondering whether I should add the 150aa to the end of the sequence file and add them to the fragment files in order for phenix.mr_rosetta to do density modification correctly? Or does this not matter at all? According to HHpred and others the last 200aa are beta sheets, probably a a beta sandwich or two, and the 150aa component consists of helical elements but that is as close as it really gets. Cheers, Morten
