not to muddy the gel issue, but I wonder if the whole solution for
gels and fragments could also be part of the solution for restriction
maps and fragments. That is, can we come up with a representation for
bands that would be versatile enough for both of these needs?
I bring this up because Richard notes in his proposal:
> It does forbid two distinct bands of exactly the same size
If the gel/fragment model also supported restriction maps, it would
need a list structure (REPEAT) to provide for same-sized fragments.
I am not suggesting that the gel display and restriction map display
be the same, only that their underlying models might share enough
features that we could join them and have a single, unified
representation for fragments.
