About


Cliping and Keeping Information Trimmer (ClipKIT) was developed as part of Jacob L. Steenwyk’s graduate thesis work.

Since the early 1990’s, multiple sequence alignments have been filtered or “trimmed” to remove sites that may cause errors in phylogenetic inference. Errors can be caused by erroneously inferring site homology or saturation of multiple substitutions, both of which often present as highly divergent sites. However, recent analysis by Tan et al. (2015) revealed current methods of alignment trimming often resulted in worse phylogenetic inferences. These findings highlight the need for alternative MSA trimming strategies.

In light of these findings, we developed ClipKIT, which implements an innovative yet simple trimming strategy. ClipKIT achieves this by identifying and retaining phylogenetically-informative sites rather than identifying and trimming highly divergent ones. Our assessments of ClipKIT’s performance using empirical datasets of Mammalian and Yeast sequences and simulated sequences from metazoans, flowering plants, filamentous fungi, and budding yeasts (see details here) suggests ClipKIT is a top-performing software.
