Hello everyone!

I had 16S rRNA sequence data obtained from 21 samples which are separated into two groups. I performed functional community prediction with these 16S sequences using MicFunPred tool. Then, I obtained an ortholog table (KO table) like OTU table. Using this table, I did differential abundance analysis to see significantly abundant features between two groups. When I use fdr correction I got a few statistically significant KOs.

I was tasked to find pathways from those significant KOs. I searched many articles and they mostly used Ingenuity pathway analysis tool or other commercial tools. Does anyone know of free, open source tools for microbial pathway analysis? or I am open to any advice/idea on finding pathways with the KOs information I have obtained.

Thank you all!

Not exactly my field of expertise, but maybe you can get some inspiration for tools from nf-core ampliseq pipeline. Possibly some of the tools from the funcscan pipeline will also run with the input that you already have?

Try paprica or PICRUSt2. Pathway prediction based on 16S rDNA metataxonomic reads is exactly what they do. I hope I understand your task correctly.

Also, there are some analogous tools listed and compared in “Inferring microbiota functions from taxonomic genes: a review”.

What concerns paprica, you can find some useful tutorials here: https://www.polarmicrobes.org/category/paprica/.
