Collection of morphological matrices (some including extinct taxa) and related phylogenetic inferences

This file set contains information, and analysis files, related to morphological data matrices collected from literature (including some we published) to sum up some principal features of these matrices, mainly how tree(un)like they are.Version 5 (major update) includesXLXS-File OverviewTables summarising general signal information (behaviour under parsimony and NJ tree-building in relation to matrix and individual Delta Values, a measure for treelikeness.Content of 7z-ArchivesCycadales.7z includes the matrices of Stevenson (Mem. NY Bot. Garden, 57: 8–55, 1990) and my extension of it (Grimm GW. 1999. Diploma thesis. Eberhard Karls Universität) including extinct (potential) cycads as well as some inference based on them.HuffonMcMahon.7z includes the matrix and analysis files used for the graphics labelled HM04* and shown in the related post on Genealogical World of Phylogenetic Networks (GWoN): The curious case(s) of tree-like matrices with no synapomorphies.Renner_et_al_SupplementaryData.7z includes the primary test matrix and inferences of Renner, Grimm, Sokoloff (submitted), Surviving ancestors, hard polytomies, and seed plant evolution to reconstruct a Romerogram of seed plant evolution; and additional matrices revisited in course of that study.SookiasTestData.7z includes the Crocodilian morpho-matrix included in the SI of the Sookias (PaleorXiv, 2019) and analysis files used for the graphics shown in the related GWoN post: Has homoiology been neglected in phylogenetics?VariousDinos.zip includes NEXUS-reformatted dinosaur matrices provided as supplement to Yang et al., PeerJ, 2020: birds and related Theropoda with 505 taxa and 700 characters and Hartman et al., PeerJ, 2018: Ornithischia 62 (one duplicate) taxa, 263 characters.Important note: When using the NEXUS-formatted matrix files make sure to cite the original works (see readme text files in each archive). Cite this collection to refer to results/inferences done by me (links below) or included here, and to credit the source from which you obtained the file.Matrices are provided in ready-to-use NEXUS format (*.nex), trees in NEWICK (*.tre – single tree; *.tree[s] – tree collections) and networks in Splits-NEXUS format (*.nxs; *.dist; use SplitsTree to open and view files): MPT = most-parsimonious tree samples, BioNJ = neighbour-joining tree fulfilling the least-squares optimality criterion, MD = neighbour-net splits graphs using simple (Hamming) mean morphological pairwise distances, NJBS and PBS = NJ and parsimony bootstrap pseudoreplicates.
