Thanks for the quick responses for the questions on Qiime2. I really appreciate it.
I have followed tutorials in "Moving Pictures", and came up to beta-diversity analysis.
I would like to analysis with bray_curtis_distance_matrix, but it comes with an error "Invalid value for '--i-distance-matrix': Expected an artifact of at least type DistanceMatrix. An artifact of type PCoAResults was provided.".
This is my metadata file.metadata.tsv (292 Bytes)
Thanking for your advises.
