Hi,

I am using MICOM for the rumen metagenome sequencing data. Follows are my command from building models to get growing models.
data = pd.read_csv("sheep_188SGB_indicator.head283.genus.species.csv",sep=",")

`manifest = build(data, "qua/agora103_genus.qza", "models", cutoff=0.0001, threads=2)` And Mr. Sean Gibbons share us the medium of rumen diet. So we used the rumen medium here:

medium = load_qiime_medium("rumen_diet_control_complete.qza")

Many warnings happened as follows:

Finally, we got an error here.

I am so confused about what's wrong in my pipeline. Hope for any reply. Thanks for your time and work.

Hi,

the issue are the samples with no matched taxa (S1_1 and S1_2). Those will be empty models and the error is coming from those. You could filter your manifest and remove those and it should work for the remaining samples.
