failed annotating the example vcf file in the installation folder of VCFtools

[jianfeng.mao]

Dear SEQanswers,

I need your helps on fixing problems I faced when annotating the
example vcf file (annotate.txt) in the installation folder of
VCFtools. I have listed the commands I used and the results I got.

Also, I want to know what type of annotation information file it
(VCFtools) supported, gff file or others?

cat annotate-test.vcf | vcf-annotate -a annotate.txt -d
key=INFO,ID=ANN,Number=1,Type=Integer,Description='My custom
annotation' | bgzip -c > annout.vcf.gz
Can't use an undefined value as an ARRAY reference at
