[PyMOL] symmetry and density maps

2006-08-05 Thread Richard
I just loaded a CCP4-format density map and am having a little trouble getting the map to cover the area of interest on the model. The displayed map covers the entire unit cell, but the model I am working with is located at the bottom corner with many of the atoms spilling over into neighbo

Hi Richard, Unfortunately, PyMOL will not do symmetry expansion. You could use ccp4s mapmask to extend an existing map around a molecule. An example script is below (BORDER is the number of angstroms around the input model to calculate the new map) mapmask \ XYZIN model.pdb \ MAPIN previous_m
