     'poor NMR people'? gee, I think they are the richest!!  :-)
   
      [couldnt help looking at my bank(ruptcy) account!]  :-(

   Stereochemical information was not the contribution from modellers and 
   instead, most of them obtained from small molecular and inorganic crystals 
   by crystallography. In any case Crystallography is a SuperSet encompassing
   all the available knowledge; not just X-ray information.

   Obviously Gerard has been trying to suggest some SIMPLE test to a 
   relatively newcomer and never claimed it to be THE TEST. So, why
   keep on harping about it?

   In today's world if someone asks for a program to generate a 3D 
   structure from a sequence, then he needs to be cautioned. It surprises 
   me to see that homology modellers possess a fragile psychology that 
   makes them take offence at the slightest remark that was not intended 
   for slighting.

   ...er..I am getting scared of chemists, molecular biologists, computer
   scientists and physicists entering the newsgroup now...they might start 
   taking away the credit from us crystallographers!!  :-)
