Hi Tassos, Tim,

I wonder why would you or anyone on this list worry whether biological
questions that can be asked and answered with structures are relevant to
justify the resources? I think there is abundant evidence that this is the
case. Unless your point is that crystallography is now dead for all practical
purposes... then yes, I fully agree :-) It would however be wrong to erase its
historical contribution to understanding biology.

Best wishes,

Radu
