I am having problems importing my HTSeq count data- it tells me the counts are zero when this is clearly not the case when head outputs:

>head(WTCHG_862660_71955267)
    GeneID WTCHG_862660_71955267
1     A1BG                   148
2 A1BG-AS1                   196
3     A1CF                     0
4      A2M                     1
5  A2M-AS1                    79
6    A2ML1                     0

This is the script:


#this works
metadata <- read.csv("Meta_data_clones_vs_vbneg.csv")
metadata
print(metadata)

#this adds in a column to say what the file name is in the metadata file
metadata = mutate(metadata, countFile = paste0(metadata$SampleName, ".stranded-counts.txt"))
metadata <- lapply(metadata, as.character)
metadata

#this works and makes the sample table
mysampleTable <- data.frame(sampleName = metadata$SampleName, fileName = metadata$countFile, condition = metadata$Condition)
print(mysampleTable)

#this creates the table of counts
DESeq2Table <- DESeqDataSetFromHTSeqCount(sampleTable = mysampleTable, directory = "H:/R/htseq_counts_vbneg_pos/", design = ~condition, ignoreRank = FALSE)


# include your problematic code here with any corresponding output 
#Error in DESeqDataSet(se, design = design, ignoreRank) :

I tried manually adding a column with row numbers (using the rowid_to_column) function but it returned the same error message.

Anyone help?? I've going round and round for days with this.

I think it would be hard to help you as it stands, could you share what mysampleTable looks like ? Have you checked the filenames correctly match with your directory ?

This is the head of mysampleTable and yes the file names do match.

      sampleName                                  fileName condition

Everything seems fine here, so I suppose there might be a problem with the txt files. Is there any row header in your txt files ? If yes, just remove it and it might solve the issue

Yes! There was a header in the text files that just read '0'. I removed it manually and it works fine now.

If you look at the examples in the vignette, the rownames of the sample table and counts files are not just row numbers.
