Cool, thanks a lot Pavel, I’ll try to understand that a bit further. From what I can see, I could very well also read the A and B.ccp4 from an outside file and use the same subsequent code to run the super positioning, right? Thanks again, that’s really helpful. Peter

Hi Peter,

I'm attaching example code that does it.

Hi all,

I'm trying to find sample code or documentaiton on how to do the following:

I have a density map and a rotation/translation matrix (numpy matrix) and I'd like to apply it to the density map at hand and write the transformed map again. I know that phenix allows to superimpose structures and underlying densities but I couldn't find how to do this programatically with cctbx.

Thanks in advance for your help
