WebAug 16, 2024 · Method 2 is strongly recommended over Method 1. We recommend that you either use topTable without a FC cutoff or use topTreat. Unlike ordinary t-tests, limma always prioritizes large fold changes over small fold changes, whether you use treat or not, so the use of naive FC cutoffs is unnecessary and actually harmfull.

WebThe use of eBayes or treat with trend=TRUE is known as the limma-trend method (Law et al, 2014; Phipson et al, 2016). With this option, an intensity-dependent trend is fitted to the prior variances s2.prior . Specifically, squeezeVar is called with the covariate equal to Amean, the average log2-intensity for each gene. WebMay 27, 2024 · fit: an MArrayLM fitted model object produced by lmFit or contrasts.fit.For ebayes only, fit can alternatively be an unclassed list produced by lm.series, gls.series or mrlm containing components coefficients, stdev.unscaled, sigma and df.residual.. proportion: numeric value between 0 and 1, assumed proportion of genes which are differentially … WebThe logCPM values can then be used in any standard limma pipeline, using the trend=TRUE argument when running eBayes or treat.
