CNRegions gives error in IRanges Package
Entering edit mode
Last seen 4.2 years ago

I am handling CNV data. While running CNregions function for iClusterPlus the way they have shown here (

> cnv=CNregions(seg = cnv_seg, epsilon = 0, adaptive = FALSE, rmCNV = TRUE, cnv = variation.hg18.v10.nov.2010, frac.overlap = 0.5, rmSmallseg = TRUE, nProbes = 5)
Removing CNV... 
Error in .Call2("solve_user_SEW0", start, end, width, PACKAGE = "IRanges") : 
  solving row 1: negative widths are not allowed

I have checked that the width are non-negative. The same error is coming even if I am using the gbm.seg data (a subset of the glioblastoma dataset from the cancer genome atlas (TCGA) GBM study (2009) used in Shen et al. (2012 ), available in R).

The IRanges version 1.99.19 mentioned here ( IRanges ) is not available for download which has solved this bug. Please help me out with this problem.

How to solve?

You need to provide a self-contained example data set that gives the error, which people can use to track down any problems. The IRanges package is pretty mature, and thousands of people have used it without problems, so it is more likely that you misunderstand the error rather than there being a bug in IRanges.
