Strand alignment error

[ConnieXuhm]

HI, when I try to do the strand flip process by using the pre-phased shapeit2 data, with the reference panel as 1000 genome phase3 (.vcf.gz format), I encounter the following problem. Please help me, thanks!

My code is
java -jar GenotypeHarmonizer.jar --input 1118_noflip.phased1 --inputType SHAPEIT2 --ref ALL.chr1.phase3_shapeit2_mvncall_integrated_v5a.20130502.genotypes --refType VCF --output 1202_GH --update-id --outputType SHAPEIT2

And the error presents:

it seems that either the vcf.gz file or the tbi file are corrupt. You could try running the vcf-validator (https://vcftools.github.io/perl_module.html#vcf-validator) to verify this.
