Hi, I am trying to launch some analysis using the BAnOCC package, but I am having some problems.
I am working at the ASVs level, with a dataset of 7 samples that after filtering ASVs, and retaining those that have a relative abundance > 10-4 in at least one of the samples, I am left with around 400-500 ASVs.
I have read the article and the tutorial. Arriving at these parameters:
b_fit ← banocc::run_banocc(C = input_reptop_skin_genus, compiled_banocc_model=compiled_banocc_model, chains = 4, cores = 4, iter = 5000, a = 0.5, b=10, verbose = TRUE).
Warning: There were 8 divergent transitions after warmup. See
to find out why this is a problem and how to eliminate them.
Warning: Examine the pairs() plot to diagnose sampling problems
Warning: Bulk Effective Samples Size (ESS) is too low, indicating posterior means and medians may be unreliable.
Running the chains for more iterations may help. See
Begin fitting the model
Please, could you help me to fix those warnings and adjust the parameters properly? Thanks in advance.
