I’m trying to calculate Chao1 confidence interval. I got the chao1_ci.qza file, but when I trying to get chao1_ci.qzv file, with this command “qiime metadata tabulate --m-input-file chao1_ci.qza --o-visualization chao1_ci.qzv” it gives an error message
"There was an issue with viewing the artifact chao1_ci.qza as QIIME 2 Metadata:
Unable to parse string “(78, 78.0)” at position 0"
What does it mean?
