Thanks to Michael and Julian for taking care of this. Fixes are in
devel, >= 1.13.15.

Looks like an issue when expand()ing the VCF. Maybe Val could take a look?

Hi,
The conversion from a 'VCF' to 'VRanges' object fails if an INFO field
with multiple values for different ALT alleles is present:
Here an example VCF entry for which this fails (line 71151250 in
'ALL.wgs.phase3_shapeit2_mvncall_integrated_v5.20130502.sites.vcf.gz'
, taken from
ftp://ftp.1000genomes.ebi.ac.uk/vol1/ftp/release/20130502/ALL.wgs.phase3_shapeit2_mvncall_integrated_v5.20130502.sites.vcf.gz
):

The respective code to reproduce this:
library(VariantAnnotation)
roi = GRanges("17", IRanges(1e7+1541, width = 1))
vcf = readVcf(path, "GRCh37", ScanVcfParam(which = roi, info = "AF"))
## 'info = character()' and other versions also cause the error
vrc = as(vcf, "VRanges") ## error
fails with
Error in colSums(ielt) : 'x' must be an array of at least two dimensions
This occurs both with the latest version of VariantAnnotation in
bioc-release and bioc-devel.
Best
Julian
