I have recently acquired some 16S metagenomics data, and was wondering if anyone can speak of the potential limitations, challenges as well as advantages to conducting a network-based study on metagenomics, such as what is done w.r.t co-occurrence networks.
I thought it would be interesting to deviate from the "classic" study of taxonomic abundancies present in different timepoints / conditions. However, it seems as though for such studies they are usually dealing with a relatively large number of samples - please find paper below:
Could such analyses be done with much smaller sample sizes such as those generated via mouse models? What are the potential limitations of such an approach, and how could they be overcome?
