file_transformation: 
  - The markers in this collection correspond with the GBS diversity collection Wm82.gnm2.div.Hashemi_Perry_2022
  - The following changes were applied to the VCF file original_GBS_SoyMAGIC.vcf described in Hashemi et al., 2022 
  - Sequence accession IDs for chromosomes were changed from e.g. CM000834.2 to glyma.Wm82.gnm2.Gm01
  - Marker IDs were changed similarly, e.g. from SCM000834.2_8115 to Gm01_8115
  - Marker positions were projected from locations in assembly GCF_000004515.4 ("Glycine_max_v2.0")
      to assembly GCF_000004515.5 ("Glycine_max_v2.1"), which corresponds with glyma.Wm82.gnm2.DTC4
      in the LIS/SoyBase datastore. These two assemblies (GCF_000004515.4 and GCF_000004515.5) have
      small differences due to the presence of gap and vector sequences in some pseudomolecules in the GCF_000004515.4 assembly.
  - Approximately 1.5% of the markers were omitted in glyma.Wm82.gnm2.div.Hashemi_Perry_2022.GBS_SoyMAGIC.vcf due to poor flanking sequence quality.
