Hello All,

I have differential binding sites boject obtain from diffBind (dba.report). I am using the ChIP Seeker package to annotate the peaks but keep getting the following error: Error in (function (classes, fdef, mtable) : unable to find an inherited method for function ‘NSBS’ for signature ‘"SortedByQueryHits"’

Here is my peakset

BD

I used diffloop package to add chr to the chromosome column but it did not work. Result in the same error.

Please let me know if you have any idea how to fix it. Highly appreciated.

Were you able to find a solution? I have this exact issue. Are you using the hg38 reference?

Yes,

I changed the seq level:

newnames <- paste0(c("1","2","3","4", "5","6","7", "8","9","10","11","12","13","14","15","16","17","18","19","20","21","22","X","Y","MT"))

names(newnames) <- paste0(c("NC_000001.11","NC_000002.12","NC_000003.12","NC_000004.12", "NC_000005.10","NC_000006.12","NC_000007.14", "NC_000008.11","NC_000009.12","NC_000010.11","NC_000011.10","NC_000012.12","NC_000013.11","NC_000014.9","NC_000015.10","NC_000016.10","NC_000017.11","NC_000018.10","NC_000019.10","NC_000020.11","NC_000021.9","NC_000022.11","NC_000023.11","NC_000024.10","NC_012920.1"))

peaks_with_new_seq_level <- renameSeqlevels(peaks_with_old_seq_level,newnames)
