Hi, A question: For a given PDB structure (say, 1J4N) and a given point mutation (say, C104K), I want to find all residues within 5 angstroms. Manually, this is easy to do with 'Select' --> 'Zone...', but if I have 1000 mutations, is there a way to automate the process and send results to a file? ****************** soranim@pharmacy.ucsf.edu Marco Sorani Program in Biological & Medical Informatics University of California, San Francisco
