Major changes to PhyKIT are summarized here. 1.11.3: Added an optional argument to the prune_tree function wherein instead of pruning tips specified in the input file, those tips will be kept.
1.11.2: Added an optional argument to the thread_dna function. Now, PhyKIT can thread nucleotide sequences onto a trimmed amino acid alignment. To do so, point PhyKIT to the ClipKIT outputted log file using the -c argument. The ClipKIT log file can be generated when trimming an alignment with ClipKIT by adding the -l argument (see here for more details: https://jlsteenwyk.com/ClipKIT/).
1.11.1: Modified sum of pairs score to divide the correct number of pairs by the number of pairs in the reference alignment rather than the query alignment alignment
1.11.0: Added terminal_branch_stats (alias: tbs) function to examine terminal branch lengths
1.10.1: Modified column score and sum of pairs score to divide the correct number of columns or pairs by the number of columns or pairs in the query alignment rather than the reference alignment
1.10.0: Added tip_to_tip_node_distance (alias: t2t_node_dist; t2t_nd) function to calculate the phylogenetic distance between two leaves in a phylogeny. Distance is measured in nodes between two leaves
1.9.0: Added monophyly_check (alias: is_monophyletic) function to examine monophyly among a specified set of taxa
1.8.0: Added hidden_paralogy_check (alias: clan_check) function to examine phylogenetic tree for issues of hidden paralogy
1.7.0: Added nearest_neighbor_interchange (alias: nni) function to generate all NNI moves for a binary rooted phylogeny
1.6.0: Added tip_to_tip_distance (alias: t2t_dist; t2t) function to calculate phylogenetic distance between two leaves in a phylogeny
1.5.0: Added root_tree (alias: root; rt) function to root a phylogenetic tree
1.4.0: PhyKIT is now Python version 3.9 and BioPython 1.79 compatible
1.3.0: Added function that estimates the evolutionary rate of a gene using tree-based properties. Function name is ‘evolutionary_rate’ or ‘evo_rate’
1.2.2: added function to get the subtree of the last common ancestor among a set of taxa
1.2.0: added command line interfaces for all functions so that each command can easily be executed. For example, ‘phykit aln_len -h’ can now be called using ‘pk_aln_len -h’
1.1.0: added faidx (alias: get_entry; ge) function to extract fasta entries from a multi-fasta file
1.0.3: added rooting procedure before calculating RF to handle comparing unrooted and rooted trees
1.0.2: function that calculates Robinson Foulds distance (robinson_foulds_distance; rf_distance; rf_dist; rf) now can take trees that differ in topology. PhyKIT will first determine shared tips between the two trees and prune both trees to a common set of tips. Next, PhyKIT will calculate the Robinson Foulds distance.
0.1.3: Added function (column_score; cs) to calculate the quality of an alignment given an input query alignment and a reference alignment to compare it to
0.1.2: Added function (sum_of_pairs_score; sops; sop) to calculate the quality of an alignment given an input query alignment and a reference alignment to compare it to
0.0.9: PhyKIT now handles error stemming from piping output
