[IMP-dev] query particles

[Keren Lasker <kerenl@salilab.org>]

hi all,

Frido and I find ourselves many times need to query particles based on  
attribute values.
Few such examples: a protein with a specific name, particles with a  
specific residue range.
I think that it would be very useful to have something similar to  SQL  
queries on the particles DB.
Bret might had something similar implemented  - but it is probably  
obsolete.
IMP.Atom will probably need such functionality as well.

has anyone took a look at that before ?

thank you,
Keren.
