How to manage GO terms for metagenomics
Entering edit mode
5 months ago


I have been trying to retrieve GO terms for metagenomics for a while. I already retrieved all GO IDs, however I can't collect in the main categories. Do you have any idea regarding this ?

I followed the steps below.

1- Running interproscan, and extract the corresponding GO IDs 2- Mapping the GO IDs to go.obo (

Now I want to narrow them into their main corresponding categories. Basically, I want to get kind of this figure below.

Is there any R packages or tool for this purpose? There are some R packages (gprofiler, go express, top go), however the species parameter is required. In my case, as It is metagenomic data, I do not need to use it.

Thanks ! example of GO IDs
