export with -m (merge) option

[lynnjo]

Hello -

I am using tiledbvcf to create a dataset that I would later like to be able to export as a merged vcf file. I can successfully, load and export data from this dataset. What I would like to do is export to a multi-sample vcf file. It looks like export with the -m option should handle this, though it gives me memory errors. I added the -b flag to increase this but still no luck. The command I am running:

tiledbvcf export --uri tiledb_datasets/gvcf_dataset  -m -b 65536 -o /workdir/lcj34/phg_v2/exportedHvcfs/mergedGvcf.vcf

The error I get:

Exception: SubarrayPartitioner: Trying to partition a unary range because of memory budget, this will cause the query to run very slow. Increase `sm.memory_budget` and `sm.memory_budget_var` through the configuration settings to avoid this issue. To override and run the query with the same budget, set `sm.skip_unary_partitioning_budget_check` to `true`.

Is there another trick to running the tiledbvcf export command to create a merged vcf? Thank you

I am running tiledbvcf version:
