Liftover errors with CrossMap and Picard
Hi all,
I am attempting to use CrossMap to convert my dosage files output from the sanger imputation service from hg19/37 to hg38. Here is the command I am using
python3 ~/software/CrossMap-0.3.1/bin/CrossMap.py vcf ~/Data/liftover/hg19ToHg38.over.chain.gz 22_withMAF.vcf.gz ~/Data/GenCode/GRCh38.primary_assembly.fa test_output_chr22_hg38.vcf
and I receive the following error part way through
KeyError: "sequence 'b'chr22_KI270879v1_alt'' not present"
I get similar errors when I attempt to run other chromosomes. Has anyone encountered this problem before?
Additional note: I have also attempted to LiftOver using the picard LiftoverVcf tool. When I do this happens
100.0000% of variants were not successfully lifted over and written to the output
Any help that can be given towards either tool would be appreciated!

I've been trying further and find that it works with a bed file that I've created from my vcf. Only issue is that It doesn't preserve any mapping so i can't coordinate any genotypes!
I have ever met the problem: sh: liftOver.hg19Tohg38: command not found, but have never met the problem you mentioned.
