Hello
does Mart provide any support for logical operations other than AND?
there's a paper by Peter Karp (describing his own query system) where he
asserts:
"BioMart includes a form of ‘not’ but on an individual filter element only"
which I presume means that you can't say "A, not B" but you can say "A
and 'NOT B'"
is this correct? is there any documentation for how you can do this?
best wishes,
Paul
