Dear @yiluheihei ,

Thanks for your efforts. Is it expected to not find any marker when running the run_ancombc() example?

data(enterotypes_arumugam)
ps <- phyloseq::subset_samples(
    enterotypes_arumugam,
    Enterotype %in% c("Enterotype 3", "Enterotype 2")
)
run_ancombc(ps, group = "Enterotype")

microbiomeMarker-class inherited from phyloseq-class normalization method: [ none ] microbiome marker identity method: [ ancombc ] marker_table() Marker Table: [ no microbiome markers were identified ] otu_table() OTU Table: [ 235 taxa and 24 samples ] sample_data() Sample Data: [ 24 samples by 9 sample variables ] tax_table() Taxonomy Table: [ 235 taxa by 1 taxonomic ranks ] Warning messages: 1: The group variable has < 3 categories The multi-group comparisons (global/pairwise/dunnet/trend) will be deactivated 2: No marker was identified
