[modeller_usage] ab initio modelling with X-ray data

Dear all:

We have obtained a low resolution crystallography data for our protein, and we want to add it as restrain condition for ab initio modelling with MODELLER, just like the tutorial 5: Modelling with cyro-EM does, could it be done? And the data format of density map from crystallography is sca or mtz, while from EM it is mrc, how to fix it?
