I performed ANCOM on my data looking at two clinical groups (weight gain vs weight loss), and I'm not sure if the taxa (at genera level) are statistically different between the groups, as the W value for some is 0. Please see attached qzv file.
Note: the feature table is filtered so that any feature that is not present in ~10% of the samples is not included.
Can you help me interpret the results? And if there is anything I can do differently?
I've read this forum post already but not sure I quite understand it and how I can apply it to my data.
Using qiime2-2022.8 version
Command I'm using:
qiime composition add-pseudocount
qiime composition ancom
