Hi,
I've run into a frustrating problem: when lifting over certain VCFs from b37 to hg38, I'm running into LiftoverVcf exiting with errors like Exception in thread "main" java.lang.IllegalArgumentException: Duplicate allele added to VariantContext
I've got it isolated to an example failing variant, but I'm at a loss for how to fix or prevent this error, since they seem scattered among VCFs I've generated with GATK 3.8-1-0-gf15c1c3ef GenotypeGVCFs.
Picard version 2.20.2
$ java -jar picard.jar LiftoverVcf --version
2.20.2-SNAPSHOT
Failing variant example:
$ java -jar picard.jar LiftoverVcf C=/gpfs/gpfs2/cooperlab/resources/liftover_chain_files/b37ToHg38.over.chain.gz I=bad_simple.vcf O=test.vcf R=hg38.fa REJECT=test_b37.reject.vcf

Resources I'm using:
1. chain file from https://raw.githubusercontent.com/broadinstitute/gatk/master/scripts/funcotator/data_sources/gnomAD/b37ToHg38.over.chain
2. reference from ftp://hgdownload.soe.ucsc.edu/goldenPath/hg38/bigZips/hg38.fa.gz
3. Sequence dictionaries from picard CreateSequenceDictionary
File provenance: GRCh37 GVCFs generated by DRAGEN variant caller in --vc-emit-ref-confidence GVCF mode, joint-genotyped with other samples with GATK 3.8-1-0-gf15c1c3ef
I've also tried:
1. Lifting over from b37 -> hg19 (successful) and then hg19 -> hg38 (same failure) using the chain files and hg19 reference from UCSC; all of the above using the reference from the GATK Resource Bundles.
2. Adjusting LIFTOVER_MIN_MATCH which results in no variants successfully mapping (preventing the java error)
3. Adjusting RECOVER_SWAPPED_REF which has no effect on this error
4. CrossMap (v. 3.4 runs into python errors; v. 3.3 has mapping problems with b37 when "chr" isn't used in chromosome names)
Any advice would be appreciated!
Thanks. ![:)]( ":)")
