Help Pages

adjust_pvalues Adjust p-values and perform threshold filtering based on the adjusted p-values.
buildZINB Build zinb model.
callQTL callQTL: Uncover single-cell eQTLs exclusively using scRNA-seq data. A function designed to identify eQTLs from scRNA-seq data.
checkSNPList Check if the SNP ids in the input genotype matrix are valid.
CPM_normalize Normalize the gene expression matrix with CPM.
createGeneLoc Create gene location dataframe.
createQTLObject createObject:Create the eQTLObject. We next create a S4 object. The object serves as a container that contains both data (like the count matrix) and meta.data.
createSNPsLoc Create SNP location dataframe.
DESeq_normalize Normalize the gene expression matrix with DESeq.
draw_boxplot Generate a boxplot of expression levels by SNP factor
draw_histplot Generate a hist plot of expression levels by SNP factor.
draw_QTLplot Create a combined plot with violin, boxplot, and scatter point overlay.
draw_violinplot Generate a violin plot of expression levels by SNP factor
