Sample Correspondence Check

This form, which appears before any analysis is undertaken, is shown if the result of a

comparison of sample titles in the Biological and Environmental data arrays shows

them to be unmatched. The first column shows the order of titles in the Working

Biological Data grid and the second the order of samples titles in the Working

Environmental Data grid. Here, we deleted data for Site 2 in the Biological Data in

order to create the disparity shown here. The third column indicates whether the two

match. The comparison is not case sensitive.
