I'm trying to create a set with my .BAM file that was generated from reduced "paired end" sequencing (using restriction enzyme), I can easily run it as "single end", but when I add "paired = T" in the command, this message appears:

> MeDIP_RJF_AV163=MEDIPS.createSet(file=RJF_AV163, BSgenome=genome, extend=extend, shift=shift, uniq=uniq, window_size=ws, chr.select=chr_all, paired=T)

Error in .Call2("solve_user_SEW0", start, end, width, PACKAGE = "IRanges") :

Some one knows how to figure it out this problem?
