Popular answers (1) SD for fold-change makes no sense because of two reasons: 1) SD is a property of the data - but your fold-change is an estimate. 2) it has an interpretable meaning only for ... Fold change: For a given comparison, a positive fold change value indicates an increase of expression, while a negative fold change indicates a decrease in expression. This value is typically reported in logarithmic scale (base 2). For example, log2 fold change of 1.5 for a specific gene in the “WT vs KO comparison” means that the ...

May 13, 2016 · Calculate fold change. Hi, I am trying to calculate the fold change in expression of several hundred genes. If the fold change from my control condition to my experimental condition is greater or equal to 1 then there is no problem, but if the gene expression is lowered, i.e. less than one, I would like the cells to display the negative reciprocal.

val = rnorm(30000)) I want to create a data.frame that for each id in each group in each family, calculates the fold-change between its mean val and the mean val s of all other id s from that group and family. Here's what I'm doing now but I'm looking for a faster implementation, which can probably be achieved with dplyr: ids <- paste0("i",1:100)A positive log2 fold change for a comparison of A vs B means that gene expression in A is larger in comparison to B.
