Hi,

I am having problems with constructing a heatmap for my dds data.

Code should be placed in three backticks as shown below. The codes I am using are given:

```dds1 <- DESeqDataSetFromMatrix(countData = countData, colData = colData, design = ~ genotype + treatment) dds1 <- DESeq(dds1) res1 <- results(dds1) sigs <-sigs(sigs$padj < 0.05) resSig <- res1[ which(res1$padj < 0.05), ] df <-as.data.frame(resSig) df df.top <- df[ which(df$baseMean > 50) & abs(df$log2FoldChange) > 0.5, ] df.top <-df.top[order(df.top$log2FoldChange, decreasing = TRUE), ]'"

this gives me the genes with absolute 2logfoldchange >0.5 and filters out genes with less than 50 basemean. then i log normalize the dds data. "'rlog_out <- rlog( dds1, blind = FALSE)"'

"'mat <-assay(rlog_out)[row.names(df.top), rownames(colData)]"'

when i run the above code to convert my normalized data to matrix format I am presented with this error

Error in assay(rlog_out)[rownames(df.top), rownames(colData)] : subscript out of bounds.

i suspect this has to do with the colData and the normalized data. What I gathered from the tutorials was that the colData should have the isolates ID and not serial row numbers as I am observing for my colData, shared below:

""rownames (colData1)"' 1 "1" "2" "3" "4" "5" "6" "7" "8" "9" "10" "11" "12" "13" [14] "14" "15" "16" "17" "18" "19" "20" "21" "22" "23" "24" "25" "26" [27] "27" "28" "29" "30" "31" "32" "33" "34" "35" "36" "37" "38" "39" [40] "40" "41" "42" "43" "44" "45" "46" "47" "48" "49" "50" "51" "52" [53] "53" "54" "55" "56" "57"

"'view (colData)"' colData of our study set

I am also confused about the rlogtransformed data. When I ran the code "'assay(rlog)"' got the following: [1,] 11.7475488 [2,] 11.1782859 [3,] 9.7768088 [4,] 8.3933343 [5,] 6.2142404 [6,] 9.3677442 [7,] 11.3905586 [8,] 10.9357319 [9,] 11.5100845 [10,] 9.4760910 [11,] 10.5400167 [12,] 10.7315200 [13,] 9.9845541 [14,] 10.4433000 [15,] 8.4034379 [16,] 10.0455839 [17,] 9.3174048 .....

Okay the error was resolved by taking the ID_samples as row names.
