I am trying to use the trackViewer package to create a lolliplot plot to portray the variants in the fut3 gene from the 1000 genomes .popvcf file for this locus. I am able to replicate the example given in the trackViewer vignette but when I alter the code to plot fut3 variants I get this error, "Error: allwidthSNP.gr[[i]]) == 1) is not TRUE"
Below is the code from the trackViewer vignette that works fine.
> library(VariantAnnotation)
> library(TxDb.Hsapiens.UCSC.hg19.knownGene)
> library(org.Hs.eg.db)
> fl <- system.file("extdata", "chr22.vcf.gz", package="VariantAnnotation")
> gr <- GRanges("22", IRanges(50968014, 50970514, names="TYMP"))
> tab <- TabixFile(fl)
> vcf <- readVcf(fl, "hg19", param=gr)
> mmutation.frequency <- rowRanges(vcf)
> mcols(mmutation.frequency) <- cbind(mcols(mmutation.frequency),
+ VariantAnnotation::info(vcf))
> mmutation.frequency$border <- "gray30"
> mmutation.frequency$color <-
+ ifelse(grepl("^rs", names(mmutation.frequency)), "lightcyan", "lavender")
> ## plot Global Allele Frequency based on AC/AN
> mmutation.frequency$score <- mmutation.frequency$AF*100
> seqlevelsStyle(gr) <- seqlevelsStyle(mmutation.frequency) <- "UCSC"
> trs <- geneModelFromTxdb(TxDb.Hsapiens.UCSC.hg19.knownGene,
+ org.Hs.eg.db,
+ gr=gr)

Below is the code after I have made adjustments to plot the lolliplot for variants in the fut3 gene.
