Hi hail team! I have a question about extracting chromosomal start and end positions from MatrixTable partitions. I need to export a large callset to VCF (sharded) and report the first and last locus of each VCF shard. Is there a fast way to get this information from the MatrixTable partitions being exported? Or would it be faster to query each VCF shard?
I’d appreciate any ideas – thank you!!
