Ancestry-constrained phylogenetic analysis supports the Indo-European steppe hypothesis: Supplementary materials
Year: 2015
Type: article
Abstract: The supplementary materials contain details of our BEAST analyses.Note that in addition to the four blocks of analyses (A-D) mentioned in Experiments ( §6), there is a fifth block of eight analyses (E1-8) in which each ancestral language in A1, in turn, has its ancestry constraint removed.This document contains the following: S.1 A synopsis of elements that vary between analyses.S.2 A description of accompanying electronic files.S.3 Summary trees and summary statistics for each phylogenetic analysis. S.1 Analyses names and descriptorsEach BEAST analysis has a name (e.g.A1) and a descriptor (e.g.a1-c0-d0-g1-l2-s1-t1-z8) whose elements denote the following: a Ancestry constraints.0 No. 1 Yes.c A set of clade and time constraints, and a set of languages ( §4.1).0 Narrow dataset, no time constraints on splits. 1 Medium dataset, no time constraints on splits. 2 Broad dataset, no time constraints on splits.3 Narrow dataset, time constraints on splits in Table 12. 4 From Bouckaert et al. (2013).5 Same as c4, but excluding six sparsely-attested languages.d A dataset. 0 ielex on April 21, 2013, with amendments by C.C. and A.G. 2 Dataset backformed from Bouckaert et al. 2013 g A set of meaning classes.0 92 meaning classes. 1 143 meaning classes. 2 197 meaning classes.3 All 207 meaning classes in ielex.l Loan encoding (Table 5).0 Loan exclusion.2 Loan inclusion.1 s Trait model.0 SDC (no among-trait rate variation). 1 RSC with gamma-variate among-trait rate variation.2 RSC without among-trait rate variation.4 Covarion without among-trait rate variation.t Tree prior. 1 Generalized skyline coalescent. 2 Constant population coalescent.u If given, the adjoining eight bit number specifies, for each ancestral language, whether an ancestry constraint is used (1) or not used (0).x If given, the adjoining eight bit number specifies, for each ancestry-constrained language, whether its time constraint is ignored (1) or used (0).z If given, the adjoining number specifies the MCMC chain length, in multiples of 2 × 10 7 ; or else the chain length is 2 × 10 7 . S.2 Electronic filesThe datasets d0 and d2 are in files sup/ielex-130421-ag-cc.txt and sup/ielex-betal.txt,respectively.The files associated with each analysis can be found in the directory sup/runs-post/ descriptor .Each such directory contains:ieo.xml XML configuration file.info.txtInformation about the configuration.
