  # Title: Add "seq_member_projection" tables
  #
  # Description:
  #   The tables will be used to hold genebuild information about transcript
  #   projections. The pipelines will use the table to classify the projections
  #   in the same clusters as their source.
  #   There are two tables: one that has links to stable_ids (as loaded from
  #   the core database), and one where links are to seq_member_ids
  
  
  CREATE TABLE seq_member_projection (
    target_seq_member_id      int(10) unsigned NOT NULL,
    source_seq_member_id      int(10) unsigned NOT NULL,
    identity                  FLOAT(5,2) DEFAULT NULL,
  
    FOREIGN KEY (target_seq_member_id) REFERENCES seq_member (seq_member_id),
    FOREIGN KEY (source_seq_member_id) REFERENCES seq_member (seq_member_id),
  
    PRIMARY KEY (target_seq_member_id),
    KEY (source_seq_member_id)
  
  ) COLLATE=latin1_swedish_ci ENGINE=MyISAM;
  
  CREATE TABLE seq_member_projection_stable_id (
    target_seq_member_id      int(10) unsigned NOT NULL,
