Hello all, Just a couple of questions for Bruce. Artemis: I've tried using the "Sum of paths" feature, which I assume is the equivalent of ifeffit's ff2chi command. For some reason it doesn't work if no data file has been opened, even though the operation does not refer to any data. Its easy to work around, but perhaps something to be fixed? Atoms: Has there been any thought of allowing Atoms to open up standard crystallographic data files, even CIF files? (I know CIF can be quite complicated) Some crystallographer colleagues are hand-typing quite a few structures from cif files into Atoms, and I suspect many others might do the same. Alternately, is there a friendly programmer out there who can write a script to extract the relevant details out of cif and write an atoms input file? And while I'm about it ... it occurred to me that these questions above could well have been asked before, but as a newcomer to this list it is quite difficult to trawl through the archives to find relevant answers. Is there any possibility and/or interest in some kind of index of these discussions? Peter
