I was wondering if you could provide a working example of a GRCh38 GFF3 track. I’ve run into issues when trying to add a GRCh38 GFF3 track to samplot. The errors I see are either KeyError: Name or KeyError: Parent.\n\nI noticed a few related issues have been posted in this repo:\n\t•\thttps://github.com/ryanlayer/samplot/issues/190\n\t•\thttps://github.com/ryanlayer/samplot/issues/196\n\nI understand this is meant to be user-supplied, but it would be really helpful if the README included a working GRCh38 GFF3 example (similar to the GRCh37 example).\n\n```\nwget ftp://ftp.ensembl.org/pub/grch37/release-84/gff3/homo_sapiens/Homo_sapiens.GRCh37.82.gff3.gz\nbedtools sort -i Homo_sapiens.GRCh37.82.gff3.gz \\\n| bgzip -c \u003e Homo_sapiens.GRCh37.82.sort.gff3.gz\ntabix Homo_sapiens.GRCh37.82.sort.gff3.gz\n```\n\nThanks,\nGao","author":{"url":"https://github.com/yueyaog","@type":"Person","name":"yueyaog"},"datePublished":"2025-09-29T19:29:34.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":0},"url":"https://github.com/206/samplot/issues/206"}
