Hello @vrbana
You can use SCNIC to do these between data type correlations. To do this I am just allowing the user to use Spearman, Pearson or Kendall-Wright correlation and making a network and correlations file so nothing too fancy. I have not implemented this functionality in q2-SCNIC at this point and have plans to in the future but it won't be in the next month. If you want to use it in SCNIC then you can export the biom tables from your .qza's and then use those with SCNIC_analysis.py between.
