The following error has been encoutered while running the qiime sample-classifier classify-samples.
I have around 167 samples - the metadata column given for classifer is "subject"- which actually contain 85 healthy and 82 Diseased samples (screenshot of metadata attached just for a clarity).
I have used the same command for another public dataset and it seems to be working perfectly.
Could you please help me out to solve this issue.
Plugin error from sample-classifier:
Linkage must be computed on at least two observations.
