Build a list of comma separated genome identifiers using the checkboxes by each genome entry.
These are the 2-letter genome identifiers used by the SUPERFAMILY database. Some of the identifiers have a relation to the species name, but many do not. There are enough 2-letter identifiers for the forseable future (3844 including numbers and case sensitivity), but it is already impossible to make all 2-letter identifiers look like the species name.
