PFGE conducted for strains of the most prevalent serogroups (O26, O103, O121, and O145) showed that the patterns of O26 strains were heterogeneous (similarity coefficient
range 49%-94%) except for 5 strains (Figure 2).
This is the already presented Jaccard similarity coefficient
, which is, according to these authors, superior to other coefficients.
We constructed plots of absolute and relative oxide abundance and calculated similarity coefficients
, using both the conventional similarity coefficient
(SC) and the computationally more intensive weighted SIMAN coefficient.
For example, accession PI 229775 from Iran clustered with PI 221915 from Afghanistan, with a high similarity coefficient
Specifically, the similarity coefficient
method and the hierarchical clustering algorithm have been successfully employed to form machine part groups using 0-1 machine-part incidence matrices of the PFA.
across 25 genotypes of turmeric started from 0.00 to 0.76.
The lowest similarity coefficient
was 0.462, observed between accessions 109 and 135, whilst the highest one was 0.962, observed between accessions 68 and 126, with an average of 0.726.
Clustering was done using symmetry matrix of similarity coefficient
using UPGMA using SHAN module of NTSYS-pc.
The UPGMA-based dendrogram has clearly put all the samples in three major groups at average similarity coefficient
(0.12) as cut-off value.
2.5 (Applied Maths, Kortrijik, Belgium) using the interpretative criteria by Dice similarity coefficient
The hierarchical cluster tree analysis showed that the citrus genotypes used for the current investigations broadly divided into two major groups at similarity coefficient
of 0.53 (Fig.
The Miltenburg and Zhang analysis is restricted to array-based clustering techniques, similarity coefficient
based techniques, and seed-based techniques.
