Hi there,
maybe I'm just doing a silly error somewhere, but I get an error when
trying to locate the variants from a GRanges object.
I have a file with SNP positions, thefore I build up the GRanges this
way
> my.ranges = GRanges(
seqnames=paste("chr", my.snp.unique$chromosome, sep=""),
IRanges(start= my.snp.unique$position,
width=1))
> head(my.ranges)
GRanges with 6 ranges and 0 elementMetadata values:
seqnames ranges strand
<rle> <iranges> <rle>
[1] chr1 [ 1323144, 1323144] *
[2] chr1 [ 3544236, 3544236] *
[3] chr1 [ 6252966, 6252966] *
[4] chr1 [ 7861154, 7861154] *
[5] chr1 [10425118, 10425118] *
[6] chr1 [10502308, 10502308] *

library(TxDb.Hsapiens.UCSC.hg19.knownGene)
txdb19 <- TxDb.Hsapiens.UCSC.hg19.knownGene
#
my.locations = locateVariants(my.ranges, txdb19)
Error in initialize(value, ...) :
invalid names for slots of class RangesMatching: matchMatrix, DIM
What am I doing wrong?
thanks,
Francesco
