[pdp-discuss] question about unit-group based connectivity

[Randall O'Reilly]

Brian,

These Prjn specs are for creating different patterns of connectivity  
between units according to unit groups, not for different patterns of  
weight values -- that is actually not that easy to do without writing  
some new C++ code (a new ConSpec) because there is one conspec per  
projection, and so you'd have to create a different projection for  
each unit group to achieve this using the standard stuff -- doable,  
but not very efficient.  Cheers,

- Randy
