Hi,
I am integrating 16S rRNA sequencing data with untargeted metabolomics data, with the aim of exploring associations between gut microbial genera and metabolites related to kidney function impairment. Is rCCA an appropriate method for this purpose? If so, should I perform rCCA using the abundance tables of the differential genera and metabolites identified from previous analyses, or should I apply rCCA to the full set of genera and metabolites to identify associated genus–metabolite pairs, and then examine their relationships with kidney function?
Thank you for your assistance!
