Dear Colleagues, This exchange is a wonderful illustration of the simple fact that different scientists work differently, favoring different approach and different tools. For some, the latest and greatest formats and support systems are what they need to be productive. For a surprising large n

There seems to be some kind of a gap between users and developers as far the eagerness to abandon PDB in favour of mmCIF. I myself fully agree with Jeffrey about the ease of manipulating PDB's during work, particularly when encountering unusual circumstances (and there are many of those, as we

Questionable practice is writing an interpretation program for operations that can be handled simply at the command line. Programs that use the API that Eugene implicitly refers to are no panacea, e.g. Coot has strange restrictions on things like changing the chain label that can be fixed in a

Tim, PDB file format is good because of its simplicity and that's perhaps it. However, it cannot accommodate wealth of information that is available at the end of refinement. Of course one can keep creating remarks for PDB file etc but I guess mmCIF is just a better way of doing it rather than ugl

-BEGIN PGP SIGNED MESSAGE- Hash: SHA1 Hi Ian, yes, also as Andrew pointed at, I meant to refer to the ration of xml vs. cif rather than cif vs. PDB. My worry was that future versions of programs like refmac, phenix, or buster-TNT would only write large files (in xml-format) and no more P

I just hope that one day we all will be discussing a sort of universal API to read/write structural information instead of referencing to raw formats, and routines to query MX data, which would be more appropriate than grep (would many SB students/postdocs use grep these days? but many if them w

Tim,   Having not read Gerard Kleywegt's announcement, and not considering myself a programmer, I have to disagree with the majority of your statement. Yes, using grep on mmcif files is "awk"ward (but petfectly possible); awk on the other hand works much better. It's actually more of a pain to u
