Sequator Download ((new)) May 2026
If you work with next-generation sequencing (NGS) data, particularly RNA-seq, you know the nightmare of batch effects. You run your experiment, get your counts, but when you cluster the samples, they separate by date of extraction or sequencing run rather than by treatment group.
Open your R console and run:

# Estimate number of surrogate variables (Sv) n.sv <- num.sv(lcpm, mod, method="leek") print(paste("Estimated surrogate variables:", n.sv)) svobj <- sva(lcpm, mod, mod0, n.sv=n.sv)
Below is a definitive guide to downloading and running Sequnator/SVA correctly. Strictly speaking, "Sequnator" is a colloquial name for the SVA package in R/Bioconductor. It uses a method called Leek’s approach to identify hidden sources of variation (sequencing run, technician, time of day) and includes them in your differential expression model. If you work with next-generation sequencing (NGS) data,
# In R terminal: BiocManager::install("sva") library(sva) ?sva Now go fix those batch effects. Have a different tool called "Sequnator" in mind? If you meant a specific Windows GUI for sequence alignment, leave a comment below. But 90% of researchers searching this term actually need SVA.
Enter (often misspelled as "Sequator" in searches). This powerful tool, specifically the SVA package component (Surrogate Variable Analysis), helps you estimate and correct hidden batch effects when you don’t know what the confounding variables are. Strictly speaking, "Sequnator" is a colloquial name for
The object svobj$sv contains your new "Sequnator" variables. Add these to your DESeq2 design formula. Do not manually adjust the counts. Instead, include the surrogate variables in your statistical model:
