Consistency index phylogeny
Comparison of Consistency Index (ci), Retention Index (ri), and Length (l) for Seven Characters Optimized Into Trees Resulting from Equal Weights and Implied- weights …Bianchini, G., & Sánchez-Baracaldo, P. (2023). TreeViewer - Cross-platform software to draw phylogenetic trees (Version 2.1.0) [Computer software]. TreeViewer is a flexible and easy to use multiplatform software to draw phylogenetic trees with the option to display additional data and produce high-quality publication figures.The Manhattan Stratigraphic Measure (MSM; Siddall 1998) is analogous to the character consistency index of Kluge and Farris and works by optimizing the first appearances of the taxa as a Sankoff character on the tree and calculating the total length (L 0) of the resulting phylogeny.

The much lauded example of using the consistency index to measure phylogenetic signal objectively is the Klassen 1991 paper, which has a nice graph …Phylogeny for 26 species was studied using MEGA. The analysis shows that the tree has 81 most parsimonious site (length = 110) as shown in Figure 2. The consistency index is 0.789474, the retention index is 0.913669, and the composite index is 0.813996 for all sites and parsimony-informative sites.The consistency index (Kluge and Farris, 1969) for a single nucleotide site (i-th site) is given by c i=m i/s i, where m i is the minimum possible number of substitutions at the site for any conceivable topology (= one fewer than the number of different kinds of nucleotides at that site, assuming that one of the observed nucleotides is ancestral) sAn index contour is one of the ways that vertical dimension, or vertical scale, is demonstrated on a topographical map. The index contour represents the vertical scale on a map region by a thick solid line with the various elevations printe...

Thus I think that the dismemberment of Pterostylis (Jones & Clements 2002b) was somewhat unfortunate (see Janes & Duretto 2010 and Schuitema & Adama 2011 for …Embryophytes have been the focus of intensive phylogenetic research for decades, culminating in comprehensive, consensus-based classifications by collaborations such as the Angiosperm Phylogeny Group (APG; 53) and the Pteridophyte Phylogeny Group . This has had the effect of largely stabilizing higher classification down to the …However, from what you write it seems like your idea is to concatenate the two sequences/alignments for analysis.

It is also possible to calculate the RI or CI for individual characters. In the box, simply choose "Retention Index for Character," and the program will provide you with a list of characters. Choose a character that interests you, and repeat ... ….

The analysis was repeated with these new weights, and characters were again re-weighted ...The Abouheif's C mean index (Abouheif 1999) has been shown to be a Moran's I index computed with a specific matrix of phylogenetic weights (Pavoine et al. 2008). Thus, phyloSignal computes C mean using Equation 1 with w ij being the proximity matrix A described in Pavoine et al. ( 2008 ) and computed with proxTips(x, method = …
If another phylogeny based on the same database presents 100 steps, then its consistency index will be 88/100, that is, 0.88 .
