Dear All, I have an electron density map that apears to show something in O, but when I display it in PyMOL the map seems to be shifted in some way, that is, I can see features with the same size, shape and relative orientation, but they no longer coincide with the atomic model. I suspect a problem with designation of the coordinate axes. Any advice greatly apppreciated,
Richard Baxter The O (dsn6) map was created in CCP4 and displayed in O. The map for PyMOL was tried in CCP4 format created in CCP4, or by converting the O map to BRIX, or CCP4 format using MAPMAN, all leading to the same result.
