To use a custom feature table, you may paste one into the text area below in CSV format with columns defining segments and rows defining features. The first row of each row and column acts as a header containing feature ans segment hames (these may be changed). Data cells should contain
0 for bivalent features and
0 for univalent features.
Having an empty row in the Excel file will allow you to partition a set of features so that you can more easily locate a feature.
