[Dialing Pretty]

Dear All,
 
I am now learning coot baton peptide (or protein) building. Will you please 
tell me a website where I can download free coot tutorial with free 
downloadable PDB file and mtz file used in the tutorial as example?
 
I am looking forward to getting your reply.
 
Cheers,
