Fold change is a measure describing how much a quantity changes between an original and a subsequent measurement. It is defined as the ratio between the two quantities; for quantities A and B the fold change of B with respect to A is B/A. In other words, a change from 30 to 60 is defined as a fold-change … See more There is an alternative definition of fold change, although this has generally fallen out of use. Here, fold change is defined as the ratio of the difference between final value and the initial value divided by the initial value. For … See more • A comparison of fold-change and the t-statistic for microarray data analysis See more In the field of genomics (and more generally in bioinformatics), the modern usage is to define fold change in terms of ratios, and not by the alternative definition. However, log-ratios … See more • Ratio • Relative change • Replicate (biology) See more WebThe concept might sound rather simple; calculate the ratios for all genes between samples to determine the fold-change (FC) denoting the factor of change in expression between groups. Then, filter out only those genes that actually show a difference.
