Since the early 1990's, there has been one predominant guiding light for multiple sequence alignment trimming -
the removal of phylogenetically uncertain sites defined as those that are highly divergent; however, the
efficacy of this approach has been called into question. ClipKIT implements an alternative strategy wherein
sites with phylogenetic certainty are retained and others are removed. Our benchmarking analyses show that
ClipKIT is a reliable and top performing software.

Diverse disciplines in biology process and analyze multiple sequence alignments (MSAs) and phylogenetic trees
to evaluate their information content, infer evolutionary events and processes, and predict gene function.
However, automated processing of MSAs and trees remains a challenge due to the lack of a unified toolkit.
To fill this gap, we introduce PhyKIT, a Swiss-army knife-like toolkit for processing and analyzing
multiple sequence alignments and phylogenetic trees.
Bioinformatic workflows often rely on individual software to conduct single analyses, which makes maintaining
workflows cumbersome and threatens reproducibility. To address this obstacle, we introduce BioKIT, a versatile
toolkit that conducts diverse processing and analysis functions such as genome assembly quality assessment,
alignment summary statistics, relative synonymous codon usage, codon optimization estimation, and more.
Molecular evolution studies such as phylogenomics and surveys of positive selection often strictly rely on
single-copy orthologous genes (SC-OGs). To increase the number of molecular markers for use in molecular
evolution studies, OrthoSNAP identifies subgroups of SC-OGs nested within larger gene families using a
phylogenetically informed framework. The resulting SC-OGs are termed SNAP-OGs because they have been identified
using a splitting and pruning procedure.
orthofisher conducts automated HMMsearches among a set of proteomes using a predetermined set of orthologs.
Sequence similarity searches classify results as multi-copy, single-copy, or absent in a given genome. For
the purposes of phylogenomics/phylogenetics, multi-fasta files are generated for all sequences as well as
those that are single-copy; for gene family copy number determination, easily parsed output files contain
absolute copy number of hits from the sequence similarity search.
Sometimes phylogenies are so large it is challenging to determine the relationships among a subset of taxa. To
remedy this issue, treehouse, a user friendly GUI app, allows users to obtain subtrees from larger
phylogenies. To obtain subtrees, upload a list of tip names in the desired subtree from an inputted phylogeny
or a phylogeny from the treehouse database. Thereafter, users can download a pdf or newick file of the
subtree of interest.

Analysis of Bulk RNA-Seq data, differential expression analysis, and functional enrichment requires processing
and handling diverse data types. The LVBRS toolkit (the Latch Verified Bulk RNA-Seq toolkit) conducts end-to-end
analysis, differential expression, and functional enrichment analysis from raw reads from Bulk RNA-Sequencing
experiments using a cloud-based framework. LVBRS enables researchers to focus on interpretation of biological
data, not processing, file handling, data management, and resource allocation.
