Has anyone used the populationRanges function to read files? I did not understand the manual given by the software author.The following is an example of software usage

 grl <- GRangesList(
     sample1 = GRanges( c("chr1:1-10", "chr2:15-18", "chr2:25-34") ),
     sample2 = GRanges( c("chr1:1-10", "chr2:11-18" , "chr2:25-36") ),
     sample3 = GRanges( c("chr1:2-11", "chr2:14-18", "chr2:26-36") ),
     sample4 = GRanges( c("chr1:1-12", "chr2:18-35" ) ),
     sample5 = GRanges( c("chr1:1-12", "chr2:11-17" , "chr2:26-34") ) ,
     sample6 = GRanges( c("chr1:1-12", "chr2:12-18" , "chr2:25-35") )
)

👆This is what I didn't understand. I want to know what format I need to convert all the files detected by cnvnator into?
