Hi everyone,
I am trying to pairwise-compare OTUs frequencies across different DNA extraction methods (paired samples). I want to do this comparison for every feature in my relative-frequency collapsed table at levels 2-7.
Then I tried this
qiime longitudinal pairwise-differences \
--i-table 700703out_OTU_table_97_filtered_relfreq_l{7}.qza \
--m-metadata-file 700703out_mapping_file_gram.txt \
--p-metric featuretable \
--p-state-column DNA_extraction \
--p-group-column DNA_extraction \
--p-state-1 B \
--p-state-2 M \
--p-individual-id-column patient \
--p-no-parametric \
--o-visualization $VARTIFACT
And got
Plugin error from longitudinal:
metric must be a valid metadata or feature table column.
Debug info has been saved to /tmp/qiime2-q2cli-err-8ubeg6l4.log
Initially I thought this would work because I was just mirroring the answer by @Nicholas_Bokulich here, but obviously I am not setting the right metric. Which metric should I use to get the taxa comparisons?
Thank you in advance!
