[IMP-dev] query particles

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.
