Obtain the pathway abundance file for some specific EC

Hi, I have a list of ECs that I’m interested in and I want to get the related pathway abundance file.
I’ve noticed that HUMAnN will produce the pathway abundance file as the default output. However, this is the result of all genes.

  1. So I’m wondering, is it possible that I produce a pathway abundance file only related to the EC list I have?

  2. Or is there a way that I provided a list of genes that are related to these ECs as the input then I have the corresponding pathways abundance file?
    I know there is a mapping file of reaction-pathway mapping file: metacyc_structured_pathways_filtered provided. However in this file, it has ( or , in the reaction, I don’t know how to integrate it.

Thank you.
