Are the columns of  your HTSeq count table of different length?

can you add your design table or a snippet of the count table?

seem it is all the same dimension.. I found some problems with some name ID

When I correct now I have this error:


ddHTSeq <- DESeqDataSetFromHTSeqCount(sampleTable=SampleTable,directory="TuttoCount", design= ~ 1) #
Error in read.table(file.path(directory, fn)) :
  no lines available in input

Are you sure that all the files exist? Can you check this?

table(file.exists(file.path(dir, sampleTable[,2])))

I I use this is ok:



table(file.exists(file.path("TuttoCount", SampleTable[,2])))



Seem I resolve. The problem was some files of htseq count are empty. I I delete that files the programs work

thanks so much!
