Hi,
Thats simple enough... Do I have any control over grid ( make a tighter looking mesh for publication) grid_resolution_factor will set this - 0.33 is the default. The spacing between grid points is this number times d_min. I wouldn't recommend going much lower than 0.25, otherwise it risks misleading the reader into thinking that the map is more precise than is actually the case.
gridding of 0.33 or 0.25 or else - it's all about making an impression to an untrained eye. If you want to convey the result more or less quantitatively, put together a table, which lists all atoms in the ligand in question along with map CC, 2mFo-DFc value and mFo-DFc value (calculated per atom); and indicate how these maps were calculated (regular, OMIT, kick etc). Sure it will look less sexy than a picture, but that's for you to choose. Pavel
