[GRASS-user] r.cost - extra output needed

["António M. Rodrigues"]

Dear users,

I'm using r.cost to calculate time distances based on friction  
calculated using a road network and some other information.

 From what I understant, r.cost only outputs "accessbility" surfaces.  
The problem is I also need the identity of the nearest target  
(catchment areas or allocation surfaces or some other way you whish to  
call it).

How could I achieve this?

Thanks in advance.
António
