Hi everyone:

I met a problem when I run the DUTest as below, so I find my peaks.seurat@tools$Sierra doesn't have any thing except the rownames.

res.table = DUTest(peaks.seurat,

  •                population.1 = "W-P", 
    
  •                population.2 = "L-P",
    
  •                exp.thresh = 0.1, 
    
  •                #feature.type = c("UTR3", "exon")
    
  •                )
    

[1] "0 expressed peaks in feature types UTR3, exon"
[1] "0 genes detected with multiple peak sites expressed"
[1] "0 individual peak sites to test"
Error in [.data.frame(Tool(apa.seurat.object, "Sierra"), , c("Gene_name", :
选择了未定义的列

And my annotation_peak.txt as below:

I have no idea why it lost the information of Sierra dataframe when combine the seruat object and annotated peaks. Can anyone help me?
