Fishes of Texas Project Lucid Key Character Matrices

Below are the character matrices for the various Lucid keys available on this site. Each .csv file is current with its associated Lucid key version. Scored values are recorded as such: 0-absent (not true), 1-present (true), 2-rare, 3-Uncertain (lacking information), 4-common and misinterpreted, 5-rare and misinterpreted, 6-not scoped. Counts and numerical values are recorded using the following pattern: 1:4:5:8:10. The initial number 1 refers to the presence of data for that particular character, followed by the extreme low value: the normal low value: normal high value: extreme high value.
