Hello Biostars,
converting dataframe to Granges object using GenomicRanges::makeGRangesFromDataFrame but keeeps failing due to presumably reserved names in metadata column
but my metadata columns do not contain these
"seqnames", "ranges", "strand", "seqlevels", "seqlengths", "isCircular", "start", "end", "width"
any suggestions on how to resolve this would be greatly appreciated.
thanks

GenomicRanges::makeGRangesFromDataFrame(df=merged.biomart.hg19.cna,
seqnames.field="seqnames",
start.field="start",
end.field="end",
strand.field="strand",
keep.extra.columns = T, ignore.strand=TRUE)

Hey, what is the output of
?
please ignore the lots NA; what we see are pseudogenes
I see - thanks ekwame. The column names should already be okay, so, you should not have to specify them.
I wonder could you simply try:
