Dear all,

please could you advise : given a (tumor) BAM file and a (germline) VCF file, what tool shall i use in order to extract the Allele Read Counts for each heterozygous SNP (from the vcf file) ? Many thanks, 

-- bogdan

Dear James, thank you for reminding me. I am encountering an issue though (below): any suggestions on how to fix it it would be fabulous. Thanks a lot ;) The vcf file looks OK to me. 

 x<-VariantAnnotation::readVcf("germline.HETERO.chr19.vcf", genome="hg38")
Error in c(DataFrameList(META = meta), tbls[unique(tags)]) :

You have been around for 9 years now. Is it fair if I yell at you for using the Add your answer box to add an additional question?

Also, you have some outdated packages. You need to run biocLite to first make sure you have the latest versions before looking for suggestions. Also, giving the results of traceback right after the error would be helpful.

Thank you James for suggestions ... if you were in Palo Alto, I would have invited you for a lunch (and beer ? ;) Sometimes, I am in rush -- just too many things to do. Thanks again for advice : will do accordingly.

I've experienced this error recently as well...here you go A: Combining RangedData objects is broken (IRanges 2.8.1 with R version 3.3.3 RC) I just followed the advice here and re-installed the affected packages using type="source".
