The Sample Adequacy tab is used to identify and create potential samples, as well as manage existing ones. This tab is the sole focus of the fifth step of the workflow which allows the user to verify that the data is adequately sampled and to address issues of over or under sampling. HPMS Manager offers seven interfaces to assist in reporting samples.
