The
Heat Map Results
tab contains the following elements:
The heat map and
clustering
results are useful to find and interpret patterns of relatedness across samples in the analysis. The output relationship matrix is a square symmetric matrix representing genetic relatedness of all possible pairs of samples computed using either the
IBD
,
IBS
, or AS metric. The heat map is a visual representation of computed genetic relationships where color represents the value of the computed relatedness metric for pairs of samples. The clustering
dendrogram
on the right side and bottom of the heat map show the clustering history of the samples. Samples that are grouped closely together indicate samples with similar patterns of relatedness.
The colors on the right dendrogram indicate either groups of samples as determined by the clustering algorithm or indicate categories or values of the (optional)
Color Variable
specified from the
General
tab on the
dialog
. In general, the “warmer” (more red) the color, the more closely related the individuals. The block circled in the heat map above is an example of one such closely related group. The adjacent”colder” (more blue) blocks represent less closely related samples.
Refer to the
JMP Hierarchical Clustering documentation
for more information.
The Results on this tab are linked to the Principal Components Analysis tabs (
PCA 2D Row Scores
,
PCA 3D Row Scores
) if they are shown. These tabs are interactive; you can select rows/samples using the dendrogram on this tab and see where those samples are in the PCA analysis and vice versa.
