I am trying to analyse a ChIP-Seq data set with DiffBind. These are the contents of my sample sheet ("diffbind_samples.csv"):

SampleID,Tissue,Factor,Condition,Treatment,Replicate,bamReads,ControlID,bamControl,Peaks,PeakCaller
HC,Neutrophils,H3K4me3,HC,Ex-vivo,1,bam/merged/HC_H3K4me3.bam,HC_input,bam/merged/HC_H3K4me3_input.bam,peak/H3K4me3-healthy_control_peaks.xls,macs
ARNT,Neutrophils,H3K4me3,ARNT,Ex-vivo,1,bam/merged/ARNTHC_H3K4me3.bam,ARNT_input,bam/merged/ARNTHC_H3K4me3_input.bam,peak/H3K4me3-ARNT_peaks.xls,macs
ARDT,Neutrophils,H3K4me3,ARDT,Ex-vivo,1,bam/merged/ARDTHC_H3K4me3.bam,ARDT_input,bam/merged/ARDTHC_H3K4me3_input.bam,peak/H3K4me3-ARDT_peaks.xls,macs

When I run dba.analyze("diffbind_samples.csv"), I get this error:

Loading sample sheet...
HC Neutrophils H3K4me3 Healthy_control Ex_vivo 1 macs
Error in scan(file = file, what = what, sep = sep, quote = quote, dec = dec,  : 
  line 1 did not have 4 elements

It suggests it has something to do with the sample sheet, but I really can't find what it is wrong with it. To generate this sample sheet, I took the tamoxifen.csv file from the demo data set and replaced all the values with my own. Does anyone see what I am doing wrong? I have been stuck at this step for days now. It must be something really obvious that I am not seeing.
