Volcano plot

I am curious to know if the volcano plot generated in metaboanalyst on omics data already corrects the multiple testing, if so how?

This is a parameter (raw vs FDR) you control, assuming you are using the web page.

I made volcano and used the option y-axis p-value threshold 0.05 RAW (instead of p 0.1 by default set there). In this case i believe that it was not corrected. If i want to use corrected value, there then i should use p-value 0.05 and check the FDR option instead of raw? Please confirm
