Hi Everyone,

I am trying to run this package called NAGNAG(https://sourceforge.net/projects/nagnag/files) But in one of the commands when I run, I get this error:

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

These are commands I used:

1. altRef <- altSearch("/home/user/Desktop/hg19_ucsc.gtf", "/home/user/Desktop/hg19.fa", AStype="acceptor",transcriptNameStyle=c("standard"))

# The first command runs fine.

2. nagRef <- nagnagDetect(altRef,"/home/user/Desktop/hg19.fa")

## The second command gives an error which is
    **Error in (function (classes, fdef, mtable)  :
      unable to find an inherited method for function ‘Rle’ for signature ‘"NULL", "missing"’**

How to remove this error??

PS: nagnag package requires a lot of bioconductor packages like BiocGenerics,Rsamtools,Biostrings,IRanges etc.

Thanks
