heme group visualization/cuantification

[Alejandro Mujica]

dear all:

is there any application capable of clearly visualize an hemo 
group sorrounded by its protein from a PDB file and to measure 
-one by one- the distances betwen all the atoms of the heme 
group and all of the protein's atoms involved in the interaction 
with it? 

I have RasMol and WEBLab and I can't figure out how to do 
this with them.

Shall I ask this to any other BIOSCI group instead of this one?

Thanks a lot in advance.
