+Provenance
+----------
+
+* The FASTQ files in `gs://genomics-public-data/platinum-genomes/fastq/ <https://console.cloud.google.com/storage/genomics-public-data/platinum-genomes/fastq/>`_ were run through the DeepVariant toolchain to produce the corresponding ``*.deepvariant.g.vcf`` and ``*.deepvariant.vcf`` files in `gs://genomics-public-data/platinum-genomes-deepvariant/vcf/ <https://console.cloud.google.com/storage/genomics-public-data/platinum-genomes-deepvariant/vcf/>`_.
+* These files were then imported to Google Genomics and the variants were exported to Google BigQuery as table `genomics-public-data:platinum_genomes_deepvariant.single_sample_genome_calls <https://bigquery.cloud.google.com/table/genomics-public-data:platinum_genomes_deepvariant.single_sample_genome_calls?tab=details>`_.
+* The data was then merged to produce variants-only `multisample-platinum-genomes-deepvariant.vcf <https://console.cloud.google.com/storage/genomics-public-data/platinum-genomes-deepvariant/multisample-vcf/>`_ and  table `genomics-public-data:platinum_genomes_deepvariant.multisample_variants <https://bigquery.cloud.google.com/table/genomics-public-data:platinum_genomes_deepvariant.multisample_variants?tab=details>`_.
+
+  * The merging logic:
+
+    * groups together only single- and multi-nucleotide polymorphisms with the same reference representation and alternate allele length that originate at the same chromosome and reference position
+    * merges all insertions at the same reference position, and
+    * splits complex variants into multiple records.
+  * Individual variants with GQ < 20 are hard-masked to no-calls, with the genotype likelihoods retained.
