Create a Dataset

The first step before ingesting any VCF samples is to create a dataset. This effectively creates a TileDB group and the appropriate empty arrays in it.

Python

import tiledbvcf

uri = "my_vcf_dataset" 
ds = tiledbvcf.Dataset(uri, mode = "w") # sets dataset to "Write" mode
ds.create_dataset()                     # creates the dataset and
                                        # keeps it in "Write" mode

CLI

tiledbvcf create --uri my_vcf_dataset

If you wish to turn some of the INFO and FMT fields into separate materialized attributes, you can do so as follows (names should be fmt_X or info_X for a field name X - case sensitive).

Python

import tiledbvcf

uri = "my_vcf_dataset" 
ds = tiledbvcf.Dataset(uri, mode = "w") 
ds.create_dataset(extra_attrs=["info_AA"])

CLI

tiledbvcf create --uri my_vcf_dataset --attributes info_AA
