I am trying to run the sample classifier plug-in but I get I am getting the following error:
Shape of passed values is (73, 1), indices imply (73, 2)
For context: my feature-table has 365 samples but my metadata has 400 samples. I have less samples in the feature-table because I have filtered for low abundance and low frequency of features. Is this possibly the origin of the problem?
Moreover, I am trying to classify between two categorical variables and there are at least 50 samples of each categorical variable.
Any idea what it could be?
