Comment: C: Using RUVSeq RUVs() to perform batch correction using technical replicates
... Thanks both. The two groups have indeed not escaped my attention. There are several other variables in the experiment, both biological and technical, that can affect the PCs (e.g.: treatment, gender). I was planning to first account for the known batch effect using the technical replicates and then ...

Comment: C: RNA-seq batch correction using technical replicates profiled across batches
... Thanks Gordon. Please correct me if I'm wrong, but I think a potential problem with this approach is that batch is perfectly confounded with condition so it would not be possible to fit a model of the kind `~ batch + condition`. This is why I would like to use the technical replicates profiled acr ...

RNA-seq batch correction using technical replicates profiled across batches
... Hello, I have the following (certainly not ideal) RNA-seq experimental design: - Batch 1 contains 40 samples with condition A + 12 samples with condition B - Batch 2 contains 40 samples with condition C + the same 12 samples with condition B So, the 12 samples with condition B are technical repli ...

Using RUVSeq RUVs() to perform batch correction using technical replicates
... Ciao Davide, I would be very interested in using RUVSeq::RUVs() as it appears to be the only published and packaged method for correcting batch effects using technical replicates profiled across batches. However, I must be doing something wrong because I can't get it to work. I have a non-ideal e ...

[limma] Define contrasts for model with covariates
... I'm having a hard time understanding how to pull out the relevant contrasts when using a model with covariates in limma. Let's say I have the following gene expression matrix and experimental variables: library(limma) set.seed(16) mat <- matrix(rnorm(600), 100, 6) age <- c(45, 55, 47, 56, ...
