Re: [ccp4bb] SSM superposition of a heterodimer of related chains such that A-B and B-A / SUMMARY

2010-02-17 Thread Norbert Straeter
Dear All, last Friday I posted the following question: I have a heterodimer of two related subunits (A and B). Now I want to superimpose it using a secondary structure matching (SSM) algorithm (e.g. CCP4 superpose or the coot algorithm) such that the superposition matches A onto B and B

Norbert, Sorry for this late reply. SSM will find multiple alternative matches but most implementations just show you the 'best'. The Superposition tool in CCP4mg uses ssm and has an option to look through the non- optimal matches - hopefully one of these will be the one that you want.

Dear All, I have a heterodimer of two related subunits (A and B). Now I want to superimpose it using a secondary structure matching (SSM) algorithm (e.g. CCP4 superpose or the coot algorithm) such that the superposition matches A onto B and B onto A at the same time. For a
