Dear Jiamu,
Try out MRSAD protocol of Auto-Rickshaw
(http://www.embl-hamburg.de/Auto-Rickshaw). You can start this just by
providing your selenomet
data, starting model, sequence information and space group on the
Auto-Rickshaw server. It would do substructure determination based on
your model phase, experimental phasing, phase combination, density
modification, model building and refinement of the built model.
Iteratively it improves phases and complete your model as much as
possible.

Santosh

> I am now working on a low resolution phase determination (around 3.3 A with
> Se anomalous signal around 3.8 A).
> I can find the Se site and get the phase, but the density map is not so
> good.
> Some part of the protein (about 1/3) has a homologue model which is also can
> be found using Phaser. The homologue region has a good map while other
> region only show a poor map.
> I think the combination of experimental phase and MR phase might improve the
> map. Is there anybody can help find which program can work on this?
