Hello, I have the output of HtSeq (=count tables as .txt files) as input for R and want to use arrayQualityMetrics. Is this somehow possible? I found this in the vignette: "If you are working on one colour arrays other than Affymetrix genechips, you can load your data into Bioconductor as an ExpressionSetobject, or if you work with Illumina data and the beadarray package, as an ExpressionSetIllumina object"

I have no idea if it is possible to receive either an ExpressionSetobject or an ExpressionSetIllumina object.

count_table <- read.table("all_counts_merged2.txt", header = TRUE)"
head(count_table)
#                  id   C     T1    T2   T3
# 1 rna-XM_011330573.3    0     0     0     0
# 2 rna-XM_011330574.2    0     0     0     0
# 3 rna-XM_011330575.3    0     0     0     0
# 4 rna-XM_011330577.3    0     0     0     0
# 5 rna-XM_011330578.3  133   374   382   246
# 6 rna-XM_011330579.3    0     0     0     0

I also generated a count Matrix:

countMatrix <- as.matrix(count_table[2:5]) 
rownames(countMatrix) <- count_table$id
head(countMatrix)
#                                 id   C     T1    T2   T3 
# rna-XM_011330573.3    0     0     0     0
# rna-XM_011330574.2    0     0     0     0
# rna-XM_011330575.3    0     0     0     0
# rna-XM_011330577.3    0     0     0     0
# rna-XM_011330578.3  133   374   382   246
# rna-XM_011330579.3    0     0     0     0

PS: I handle time course data (at the moment only one replicate) C=0 h, T1=24h, T2=48h, T3=120h (h=hours)
