genNullSeqs('test.bed',genomeVersion = 'hg19',length_match_tol=500)

somthing wrong as following:

Error in (function (classes, fdef, mtable)  : 
  unable to find an inherited method for function ‘seqnames’ for signature ‘"NULL"’

please help, thanks so much

I do not know the package but it could be that the test.bed is empty or not existing at that location. Be sure to give the full path to the file like 'path/to/test.bed'.

Thanks for your reply. I just find I did not import related genome (BiocManager::install('BSgenome.Hsapiens.UCSC.hg19.masked'))

It is now working normally.
