i would like to ask about one option of the omics view. I selected type of values as "relative" and used data from "ratio of two data columns". Then, I defined the first column in my dataset as a denominator. I supposed that the result of view is a ratio of each other columns regarding the first one. But when I choose the "Add object to smarttable -> from omics data" option, I figured out that there is subtraction instead of ratio. Am I right or not?
Thank you in advance for helpful comments. Thu, 11 Feb 2016 12:34:34 -0600https://ask.pathwaytools.com/question/17866/what-is-a-correct-calculation-between-two-data-columns-in-omics-viewer/Answer by Richard for <p>Dear,</p>
