Please acknowledge your use of TreeSearch and MorphyLib in any article
in which they are used, and cite Smith (2023) and Brazeau et al.
(2019). For example, 'Phylogenetic search was performed using the R
package TreeSearch v1.5.1.9000 (Smith 2023), which uses MorphyLib
(Brazeau et al. 2017) to handle inapplicable data (Brazeau et al.
2019)'. The GUI recommends further citations for each method it
employs.
