I have successfully created a mart using my MySQL database, and I can view the
filters/ attributes in the explorer, querying works using the explorer. The
problem is that my primary key fields are missing from the explorer (but are
present in the underlying biomart version of my database). Can anyone give me
an idea of how I can get the explorer to see all my fields (including the
keys)? The PKs happen to be very important for my interface design. Is the
problem perhaps that I have multiple PKs 'MUL' (i.e. compound PKs) in my table?
Thanks
Jenny
