Re: [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 them. Tom
