using R4RNA package in R

Question

[dnyanepooja138]

Hi,

I am trying to generate a general framework for the analysis of RNA secondary structure using R4RNA package in R . But when I am giving my own helix file as input ( kept in the same directory (extdata)) gives error:

  Error in strsplit(sub("#(\\s*)", "", readLines(file, n = 1)), "\\s")[[1]] :
  subscript out of bounds
In addition: Warning message:
In file(file, mode) :
  file("") only supports open = "w+" and open = "w+b": using the former

Modifying the same file (helix.txt) already present in directory gives the same arc diagram that was there for previous file.

Is there any alternative/solution?

Thanks.
