A couple of updates to Mini Map Aide (https://minimapai.de), if anyone likes the idea of looking at maps on mobile phones, although I know many people look at their phones to get away from maps ;-
It can now draw symmetry-related molecules based on the space group symbol given in the CRYST1 card in the PDB file. At least one expert (Ian Tickle) was not very impressed with my method for generating the symmetry-mates, so do not expect the world's fastest performance! Still it should work for all of the 65 enantio-morphic/genic space groups, except for R3 and R32 which are handled as H3 and H32. A few of the more common non-standard ones also work. It should handle about 99.89 % of the crystal structures in the PDB! I also spotted recently that it was not displaying many (probably most) of the CCP4 maps which are downloadable from the EBI PDBe but that is now fixed, I think. At some stage they switched from storing maps which cover the deposited coordinates to storing the map for exactly one complete unit cell, which is quite elegant because the electron density values for a molecule that happens to be outside the cell can still be read on the fly quite easily. Do let me know of any problems. Best wishes, Jon Cooper. jon.b.coo...@protonmail.com Sent with [Proton Mail](https://proton.me/) secure email.
