Fig. 2From: SaVanT: a web-based tool for the sample-level visualization of molecular signatures in gene expression profilesSaVanT Pipeline. In the first step, an expression matrix containing values for genes in several samples is optionally converted to ranked lists of genes in samples or log-transformed. The expression matrix is then converted into a signature-sample matrix as described in Fig. 1 using the selected signatures. Optionally, the signature-sample matrix is converted to differences from mean values, converted to z-scores, and/or clustered to produce a final heatmapBack to article page
