WebFeb 15, 2024 · I do not know SLAM-seq in particular but in case you feel that genes that are supposed to be at y=0 are offset from it, then you can use the controlGenes option during normalization to focus the normalization process on these genes. You might know a set of genes that may serve as controls, or you might use genes with large baseMean (like top … WebA first exploration of counts. In this section, I will discuss the statistical models that are often used to analyze RNA-seq data, in particular gene-level count matrices. I will then use …
WebFeb 3, 2024 · First, the 'Gene Name' column should be rownames, not a column in the dataframe: rownames (dataset) <- dataset [,1] dataset [,1] <- NULL And you'll also need to change the Padj column to 'logical' (as indicated by the error): library (tidyverse) dataset2 <- dataset %>% mutate (Padj = ifelse (Padj <= 0.05, TRUE, FALSE)) WebApr 21, 2024 · I think it's where you say: dds <- dim(...) Because dim returns integers not a dataset.. If you are stuck like this, a helpful function is class().This is because class(dds) would have given you a clue what's happening.
WebApr 1, 2024 · Q2/3, recommend rowSums (counts (dds) >= 5) >= 3 and then p-values look fine to me (slight conservative slope but not worth adjusting in my opinion), you don't need to use fdrtool here, in my opinion. Use results () for p-value and adjusted p-values. WebA basic task in the analysis of count data from RNA-seq is the detection of differentially expressed genes. The count data are presented as a table which reports, for each sample, the number of sequence fragments that have been assigned to each gene. Analogous data also arise for other assay types, including comparative ChIP-Seq,
