If you have any type of ancillary data about the isolates (Demographic information, Epidemiological information, Antibiotic Resistance, Gene presence absence,etc) you can load a tab separated file to further represent it on the algorithm. This file should be a tab separated file with the first row with column headers (field names). One of the fields should be the Sequence identifier. Choose this field in the Key drop down menu to link the ancillary data to the allelic profile data. If the field does not appear in the drop down menu press the Update button. If you don't have any available data or don't wish do load any leave this fields blank an press Finish.
