Hi, Could you tell me where I can find informations of the fitting procedure of Chimera (Fit model in map)? I would particularly like to know if it is in real or Fourier space. Thank you, Magali.
Hi Magali, The Chimera "fit model in map" does a real-space local optimization. It applies rigid rotations and translations to maximize the average map value at the atom positions. It uses gradient descent. Here is info on how to use it and reference documentation: http://www.cgl.ucsf.edu/chimera/tutorials/volumetour/volumetour.html#fitmode... http://www.cgl.ucsf.edu/chimera/docs/ContributedSoftware/fitmodels/fitmodels...
