For some metrics like ilisi, emd vertical, and functional marker preservation, they are not calculated if there are less than 2 samples per group or batch because it is not possible to compute them properly.
But the checks are only done when the metric is about to be calculated, specifically within the function that does the calculation. We should write a generic function that does the checking and run it in the beginning before the metric is even computed.
This was first brought up by issue #137 when the 3 metrics returned NaN for cytonorm data
