Re: [ccp4bb] How to determine Quaternary symmetry

You can try http://www.eppic-web.org. It will give you a full enumeration of all symmetric assemblies present in the crystal. If the assembly you are looking at is not symmetric (within a certain approximation) it will not be listed in the results. Hope it helps Jose On Mon, Jul 10, 2017 at 12:

Hard to comment without more detail. What is your cell and point group symmetry? Do you know space group? What is likely asymmetric unit content? Is there a non-crystallographic translation and if so what is it? All this information given in GUI2 data processing report. Eleanor On 10 July 2017

[ccp4bb] How to determine Quaternary symmetry

2017-07-10 Thread Vands
Hi , I have a protein which has A4 stoichiometry. I am trying to find symmetry component which should be D2 but one axis looks like translated which does not make it perfect D2. I am wondering if there is any tool which I can use to determine Quaternary symmetry. thanks -- Vand
