Lastly, as Aaron Lun has pointed out, p-values should be interpreted cautiously, as the genes used for clustering are the same genes tested for differential expression.

Clustering using WGCNA - University of Texas at Austin

WebThe heatmap displays the correlation of gene expression for all pairwise combinations of samples in the dataset. Since the majority of genes are not differentially expressed, samples generally have high correlations with each other (values higher than 0.80). Samples below 0.80 may indicate an outlier in your data and/or sample contamination. WebDec 24, 2024 · WGCNA is designed to be an unsupervised analysis method that clusters genes based on their expression profiles. Filtering genes by differential expression will lead to a set of correlated genes that will essentially form a single (or a few highly correlated) modules. otc 994 freeze property taxes where to mailWebThis is good enough # for our clustering exercise, for "real" work we should go back # to the platform information, find out why there are duplicated # gene symbols, and address this issue. dat <- dat [!duplicated (gSym), ] rownames (dat) <- gSym [!duplicated (gSym)] # This completes the creation of our expression dataset for clustering. otc abstract
