+# Kids First DRC GATK HaplotypeCaller Modified Ploidy BETA Workflow
+This is a research workflow for users wishing to modify the ploidy of certain
+regions of their existing GVCF calls.
+
+## Inputs
+
+- input_cram: Input CRAM file
+- input_gvcf: GVCF generated in standard workflow
+- biospecimen_name: String name of biospcimen
+- output_basename: String to use as the base for output filenames
+- reference_fasta: FASTA file that was used during alignment. Also need
+  corresponding `.fai` and `.dict` files.
+- region: Specific region to pull, in format 'chr21' or 'chr3:1-1000'
+- dbsnp_vcf: dbSNP vcf file
+- dbsnp_idx: dbSNP vcf index file
+- contamination: Precalculated contamination value. Providing the value here
+  will skip the run of VerifyBAMID and use the provided value as ground truth.
+- contamination_sites_bed: .Bed file for markers used in this
+  analysis,format(chr\tpos-1\tpos\trefAllele\taltAllele)
+- contamination_sites_mu: .mu matrix file of genotype matrix
+- contamination_sites_ud: .UD matrix file from SVD result of genotype matrix
+- re_calling_interval_list: Interval list to re-call
+- wgs_evaluation_interval_list: Target intervals to restrict GVCF metric
+  analysis (for VariantCallingMetrics)
+- sample_ploidy: If sample/interval is expected to not have ploidy=2, enter expected ploidy
+
+## Outputs
+
+- mixed_ploidy_gvcf: Updated complete GVCF in which the desired region has had its ploidy updated
