Hello, I am a totally freshman, trying to use qiime2 sutdio(2022.2?) to analysis my data set. I have already got unifrac distance matrix and pcoa and so on. However when I try to compare the data from two groups, I get an error like " BAD REQUEST - Metadata may not be parsed with this util.". I am very confused. because I followed some sample metafile to make my metafile, I thought it should be worked. I think I made a big mistake, can anyone help me?
I paste details of my metafile below. 0 means control and 1 means administration of some drugs. 1-N or others means a name of a sample.
