GraphPCA deciphers gene spatial patterns of layer-specific marker genes in the DLPFC tissue. a Visualizations of raw and denoised spatial expressions of six layer-specific marker genes on sample 151673 of the DLPFC dataset. Benchmark methods include GraphPCA and state-of-the-art denoising tool Sprod. b Gene expression heatmaps of layer-specific marker genes on raw and denoised data generated by different methods
