The Calculate Color Groups Statistic command allows to compare the distances of Samples in two color groups. This might be useful o check the distances between Samples of subtrees or between outbreak and non-outbreak Samples.

For each of the two color groups the following values are calculated based on the currently selected columns for distance calculation (if a group contains more than one Sample):

• Minimum distance within group
• Maximum distance within group
• Average distance within group

If both color groups contain Samples, the following additional values are calculated:

• Minimum distance between groups
• Maximum distance between groups
• Average distance between groups
• Average distance of Samples in first groups to closest Sample in second group
