Welcome to SPIRAL
SPIRAL is an algorithm that relies on a Gaussian statistical model to produce a comprehensive overview of significant processes in single cell RNA-seq, spatial transcriptomics or bulk RNA-seq. SPIRAL detects biological processes by identifying the subset of genes involved and the subset of cells, spots or samples.
