Hi there,
I am using for the first time rtracklayer and I'm following the
Vignette with my own SNP data.
I am just testing it, so the task was simple, i.e. visualising the
position of a list of novel snps.
I converted a GRanges object in a data frame first, in order to follow
step by step the Vignette and reproduce the workflow, as it follows,
but as you can see I get this error which I can't find a way out for.
Thanks for your help,
Francesco
