[Gofriends] matrices from terms

Hello GO friends,
I have a list of N GO terms and I would like to generate two N by N
binary matrices. In the first (let's call it parent-child) matrix the
entry (i,j) will be 1 if and only if the i-th GO term is a parent of the
j-th term. At the second (ancestors-descendants) matrix 1's at (i,j)
entry will mean that i term is an ancestor of j term.
I am interested only in the BP ontology and also, only in "is_a"
If you could point out some tools that could do that, I would appreciate
it. I would prefer to use an older .obo file I have, so I would like the
tool to accept the obo file as input.
I probably need to do this only once (and I only have few terms) so
on-line tools should be fine.
