What is a correct calculation between two data columns in Omics Viewer?

anonymous user



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.

There are some implementation/documentation issues which need to be addressed, but the short answer to your question is that Pathway Tools is interpreting your data as being logarithmic, so the ratio would be calculated via "subtraction" rather than through division.
