how to interprete the results?

[wnddl111]

Hello,

I would like to use the files available at the following link: https://ftp.1000genomes.ebi.ac.uk/vol1/ftp/data_collections/1KG_ONT_VIENNA/release/v1.0/final-vcf/final-vcf.phased.vcf.gz.

However, I am having difficulty understanding the notation used for the variant descriptions, specifically: chr1-21837-COMPLEX->s65863s1192-104.

Could you please provide an explanation or direct me to any resources that describe this format in detail?

Thank you very much for your assistance.

Best regards,

Juyoung lee
