normalize by sum


I have ChIP seq data (counts, intergers) columns. I want to normalize the columns such that the sum in each column is the same. (Normalization by total read count).

Is there already something like that implemented? What do you suggest I could do to achieve this?



Hi Bernd,

no we don't have this method. You can do it manually. Therefore generate the sum with a group by (just group by everything) Use a table row to variable and connect it and the origin data to a math formula node. This you can then use to divide the values with the sum.
