Bioc users -

I am trying to set up the exonmap package and I have run into a problem that does not appear to be previously discussed in the mailing list. I have installed my local copy of Ensembl as well as the X-map database, as shown here. I can load exonmap library and the example data but I run into a MySQL error when I try to connect to the database. I am quite certain that I am connecting to the database because I was previously getting a different error message about user permissions. Can anyone offer any suggestions? Session info also included below. Thanks a lot.

mysql> use homo_sapiens_core_45_36g

You can turn off this feature to get a quicker startup with -A
