Method: InterMine::PathQuery::Query#summaries

Defined in:
lib/intermine/query.rb

#summaries(path, start = 0, size = nil) ⇒ Object

Return an Enumerable of summary items starting at the given offset.

summary = query.summary_items("chromosome.primaryIdentifier")
top_chromosome = summary[0]["item"]
no_in_top_chrom = summary[0]["count"]

This can be made more efficient by passing in a size - ie, if you only want the top item, pass in an offset of 0 and a size of 1 and only that row will be fetched.
