+=========================================================
+
+By default the raw read counts in the abundance matrix are normalised
+(transformed to percentages) by some ampvis2 plotting tools (for
+example ``ampvis2: heatmap``, ``ampvis2: timeseries``, and more). 
+If this is applied to data generated by one of the ``ampvis2: subset ...`` tools
+this means that the relative
+abundances shown will be calculated based on the remaining taxa after the
+subset, not including the removed taxa, if any. To circumvent this, enable
+``normalise`` when subsetting with the ``ampvis2: subset ...``` tools,
+and then disable ``normalise`` in the plotting tool. This will
+transform the OTU counts to relative abundances BEFORE the subset.
