Fold change with zero

WebMar 11, 2024 · If the value of the “Expression Fold Change” or “RQ” is below 1, that means you have a negative fold change. To calculate the negative value, you will need to transform the RQ data with this equation in Excel: =IF (X>=1,X, (1/X)* (-1)) Change “X” to the cell of your RQ data. In the Excel of the example it will be the cell “P4”, therefore: WebFoldchange is B/A => FC=1.5 or greater is Up regulated , and if the values were B=10,A=15 we'll have FC=0.66 it means all values less than 0.66 will be down regulated.
