BgenSchemaInferrer

object BgenSchemaInferrer

Infers the schema of a set of BGEN files from the user-provided options and the header of each file.

Currently the implementation is very simple. It checks if sample IDs are defined in either a .sample file or in any of the headers. If so, it returns a fixed schema that includes a sampleId genotype field. If not, it returns the same schema without a sampleId field.
