[Chimera-users] Move atoms (selections) in Chimera

Hi Dan,

  The only model building capabilities current in Chimera are commands
addaa and swapaa which add and swap amino acids, and bond rotation
capabilities.  We think creating capabilities for building models into
density maps like the program O is too big a project.  Building models
without reference to maps may be easier but I suspect molecular
dynamics capabilities or at least energy minimization are needed to
make that useful.  Chimera does not do MD calculations or energy
minimization and again that is a big project we have been reluctant to
take on so far.

  If you think specific new model building capabilities would be helpful
given the above limitations, explain them and we will be happy to consider
