Fold-change analysis
WebAug 24, 2012 · Cufflinks (Trapnell et al., 2010) adopts the delta method, a commonly used method in microarray expression analysis, to estimate the variance of the log fold change. When comparing RNA-seq data between two conditions, existing methods calculate a P -value for the differential expression of each gene. WebFeb 23, 2024 · The fold change is calculated as 2^ddCT. From which value can I calculate the mean for the representative value of all three replicates (and should I take arithmetic or geometric mean)? Should I take the average of the ddCTs first and then exponentiate it for Fold change? Or can I take the average of the 3 fold changes? bioinformatics Share Cite

WebJan 28, 2009 · For this analysis, we set the threshold value for TREAT to τ=log 2 1.5, and set the p-value cutoff for method (4) to be an adjusted p-value of 0.05, and the fold-change cutoff for method (5) to 1.5. Figure 1 shows that, when used to analyse the simulated data, TREAT has the lowest FDR overall. WebThe Fold change indicates whether a gene is up-regulated or down-regulated . For example, if we compare 2 experimental groups Wild Type versus Knock Out: Fold …
