Cross species selection scans identify components of C4 photosynthesis in the grasses

J Exp Bot
PMCID: 5429014
PMID: 27436281
DOI: 10.1093/jxb/erw256
call_split See protocol

[…] only the third position of codons. The GTR+gamma+I mutation model was used in both analyses. Resulting trees were then compared with the species phylogeny and tested for topological congruence using qdist (). Failing both phylogenetic congruence tests resulted in exclusion from further analysis. Finally 6784 ortholog groups were obtained. […]


Feature Optimization for Long Range Visual Homing in Changing Environments

PMCID: 3958223
PMID: 24556671
DOI: 10.3390/s140203342

[…] ment on the distribution quality should be judged in terms of visual homing. The chosen measure of quantitative characterization of distribution, similar to the one proposed in [], is defined as: (17)Qdist=1O×S∑o=1O∑s=1S(−∑i=1nospilog2pi)where pi is the ratio of matching features in the ith sector ring over all the ones in the scale layer (s) of the octave (o). If the correctly matching features w […]


Alignment Free Genome Tree Inference by Learning Group Specific Distance Metrics

Genome Biol Evol
PMCID: 3762195
PMID: 23843191
DOI: 10.1093/gbe/evt105

[…] al similarity (), we also calculated topological distances between trees. The topological distances between trees were calculated using the normalized quartet distance, as implemented in the program “QDist” () version 2.0, downloaded from http://birc.au.dk/software/qdist/.Note that an increase in congruence between tree topologies results in an increase in the CPCC and a decrease in the quartet di […]


Cultural Phylogenetics of the Tupi Language Family in Lowland South America

PLoS One
PMCID: 3323632
PMID: 22506065
DOI: 10.1371/journal.pone.0035025
call_split See protocol

[…] pairs of expert trees and ASJP trees for the Tupi-Guarani subgroup, obtaining normalized split distances using SplitDist (http://birc.au.dk/software/splitdist/) and normalized quartet distances using QDist (http://birc.au.dk/software/qdist). For the split distances we use an asymmetric distance measure that counts the number of splits in the first tree that are not found in the second, normalized […]


A sub cubic time algorithm for computing the quartet distance between two general trees

PMCID: 3141660
PMID: 21639882
DOI: 10.1186/1748-7188-6-15

[…] The software is available from http://www.birc.au.dk/software/qdist. It has been tested on Ubuntu Linux and Mac OS X. […]


Including RNA secondary structures improves accuracy and robustness in reconstruction of phylogenetic trees

Biol Direct
PMCID: 2821295
PMID: 20078867

[…] mpared to the respective reference tree. In this regard, two tree distance quantification methods were applied, Robinson-Foulds distances using the Phylip Package v3.68 [] and Quartet distances using Qdist v1.0.6 []. Results of all sequence sets were combined for a given scenario to receive the distributions of bootstrap values, Quartet distances and Robinson-Foulds distances, respectively. The re […]
