 # if you want a different default species selection on the Gateway
 # page, change this default Human to one of the genomes from the
 #	defaultDb table in hgcentral:
 #	hgsql -e "select genome from defaultDb;" hgcentral
 # If you need a different version of that specific genome, change
 #	the defaultDb table entry, for example, a different mouse genome
 #	version as default:
 #	hgsql -e 'update defaultDb set name="mm8" where genome="Mouse"
 #	then this defaultGenome would read: defaultGenome=Mouse

 # trackDb table to use. A simple value of `trackDb' is normally sufficient.
 # In general, the value is a comma-separated list of trackDb format tables to
 # search.  This supports local tracks combined with a mirror of the trackDb
 # table from UCSC. The names should be in the form `trackDb_suffix'. This
 # implies a parallel hgFindSpec format search table exists in the form
 # hgFindSpec_suffix.  The specified trackDb tables are searched in the order
 # specified, with the first occurrence of a track being used.  You may associate
 # trackDb/hgFindSpec tables with other instances of genome databases using a
 # specification of dbProfile:trackDbTbl, where dbProfile is the name of a
 # databases profile in hg.conf, and trackDbTbl is the name of the table in the
 # remote databases.  See below for details of dbProfile
 # 
 db.trackDb=trackDb
