  # Title: Add a table to store exon coordinates
  #
  # Description:
  #   Coordinates are assumed to be on the same dnafrag as their seq_member
  #   sequence_length is the number of characters of the sequence that can be
  #   associated to this exon. The phase of each exon is kept in the left_over
  #   column which tells the number of nucleotides that are not part of whole
  #   codons in this exon
  
  CREATE TABLE exon_boundaries (
  	gene_member_id   INT(10) UNSIGNED NOT NULL,
  	seq_member_id    INT(10) UNSIGNED NOT NULL,
  	dnafrag_start    INT NOT NULL,
  	dnafrag_end      INT NOT NULL,
  	sequence_length  INT(10) UNSIGNED NOT NULL,
  	left_over        TINYINT(1) DEFAULT 0 NOT NULL,
  	INDEX (seq_member_id),
  	INDEX (gene_member_id)
  ) ENGINE=MyISAM;
