NA p-values in NetworkModules output

[umutcakir]

Dear Pando team,

First of all, thank you for building and maintaining such a helpful program.

I have a question about the statistical output returned by NetworkModules().

NetworkModules(muo_data)@meta

In my dataset, a subset of TF–target pairs have NA in the pval and padj columns, while all other columns (estimate, n_regions, …) are filled in.
find_modules() keeps those NA entries, so they end up in the GRN.

What circumstances lead to an NA p-value? (e.g. failure to converge, low counts, all predictors dropped, etc.)

Should those NA entries be kept or filtered out before interpreting modules?

Thank you very much for your time and consideration.
