For pairwise comparisons between groups among many groups

[Phytoecia]

Hello, I am using MetaboanalystR to analyze my feature list obtained from MZmine.
I want to calculate FC and adjusted p-values so that I can list up differentially accumulated metabolites.
My list contains 12 groups and I found that FC.Anal function gives only FC of certain comparison.
I tried to specify groups to be compared by SetCurrentGroup() but it did not work..
Please let me know how to perform the above task.

Plus, I am confused where to put sample-specific normalization info in the Normalization() function.

Many thanks,
Minsoo
