• Changes requested to phenotype_cvterm for managing relationships
  • add a ‘grp_id’ to link the phenotype_cvterm table to the group module
  • Add a ‘type_id’
• Stephen Ficklin says (3/10/2015): These EQ statements seem so important to storing information about phenotypes, I'm thinking that storing them in the group will obfuscate their meaning. I can understand trying to use the group module to store these because there is no other table structure to do so. Perhaps a dedicated set of tables for storing EQs in the phenotype module is better than trying to use the group module. Another advantage to creating custom tables for EQ statements is it encourages folks to store them in the same way because they'll see the tables and natural ask how to use them.
