Ancient hybridization fuels rapid cichlid fish adaptive radiations

Nat Commun
PMCID: 5309898
PMID: 28186104
DOI: 10.1038/ncomms14363

[…] to get a dataset of the original size. The maximum likelihood tree was then inferred for each resampled dataset with ExaML (ref. ) using a GTRGAMMA model of rate heterogeneity, as recommended in the RAxML-light manual. We calculated bootstrap support values based on these 100 topologies with RAxML (ref. ). The nuclear and mitochondrial trees were rooted with the reference genome of Oreochromis ni […]


ncRNA orthologies in the vertebrate lineage

[…] of input sequence) to build genomic trees with the aforementioned strategy in a reasonable amount of time. For these families we build fast trees using FastTree2 () with options -nt -quiet -nopr and RaxML-Light (version 1.0.6) () in combination with Parsimonator v.1.0.2 (http://sco.h-its.org/exelixis/software.html), a lightweight and fast implementation for building starting trees for RAxML under […]


Whole genome sequence and analysis of the Marwari horse breed and its genetic origin

BMC Genomics

PMID: 25521865
DOI: 10.1186/1471-2164-15-S9-S4

[…] 100 25). After the filtering and pruning process, 25,854 SNPs remained and were used for the phylogenetic analysis. RAxML version 7.28-ALPHA [] was used to generate the parsimony starting trees, and RAxML-Light version 1.0.9 [] was used to carry out tree inference with the GTRGAMMA model of nucleotide substitutions. A total of 100 bootstrap trees were generated for each phylogeny. The resulting t […]


Disk covering methods improve phylogenomic analyses

[…] nt] -n [output name] -N 200 -p [random seed number] -b [random seed number] Concatenation: For the concatenated analysis, we computed a parsimony starting tree using RAxML version 7.3.5, and then ran RAxML-light version 1.0.6. We used the following commands: raxmlHPC-SSE3 -y -s supermatrix.phylip -m GTRGAMMA -n [output name] -p [random seed number] raxmlLight-PTHREADS -T 4 -s supermatrix.phylip - […]


The Candidate Phylum Poribacteria by Single Cell Genomics: New Insights into Phylogeny, Cell Compartmentation, Eukaryote Like Repeat Proteins, and Other Genomic Features

[…] and modified by Douglas Jacobsen (Bioinformatics Computing Consultant, LBNL, Berkeley, USA). The script requires two input files, the alignment file as PHYLIP format and a starting tree calculated by RAxML-Light . The script workflow is briefly summarized as follows: First RAxML version 7.3.5 creates bootstrap replicates of the multiple sequence alignments and stepwise addition order parsimony tr […]

[…] Shimodaira-Hasegawa-Like (SHL) implementation of the approximate likelihood-ratio test (aLRT; []). This involved a two-stage strategy. We first performed initial ML tree- inference using the program RAxML-Light v1.0.7 [], a modification of the original RAxML algorithm []. This program uses the GTRCAT strategy for all genes and partitions, a high-speed approximation of the GTR+Γ model (general tim […]
