WebThe log fold change is then the difference between the log mean control and log mean treatment values. By use of grouping by the protein accession we can then use mutate to create new variables that calculate the mean values and then calculate the log_fc. Whilst we’re about it, we can also calculate a -log10(p-value). WebFold-changes have the advantage of ease of interpretation and symmetry about n u m = d e n o m, but suffer from a discontinuity between -1 and 1, which can cause significant …
WebOct 11, 2024 · Fold change is ratio between values. Typically, the ratio is final-to-inital or treated-to-control *. Log2, or % are just representations of the ratio . Log2 in partcular, usually reduces the "dynamic range" of the ratios in a monotonic mapping. So rather than handling ratios between 1-1000, these map to about 0-10. WebNov 19, 2024 · norm.method.
