Coot: How to Superimpose two Structures

Jan 29, 2010

1) Open the desired coordinate files in Coot (click here if you need some help)
cns_generate(You know you have been looking at structures too long when they start to look like faces.)

2) Under Calculate you have two methods of superimposing:
SSM Superpose (we will go with this option in this example: Calculate -> SSM Superpose…) or LSQ Superpose
ssm_align_coot Note: SSM Superpose stands for secondary-structure matching and if you need to do it outside of Coot there is a server.

3) Select which PDB you would like to move and apply:
superimpose_coot
The structures should now be superimposed:
superpose

    Could you expand the tut more? How to superimpose the map together with the structure since it’s important to see the superimposed map.
    Thank you for your information!

    Hi Adward,

    I don’t believe that is currently possible in Coot (version 0.6.1).
