     - This workflow calculates the total BigQuery cost of generating this callset (which is not represented in the Terra UI total workflow cost) using the above GVS workflows; it's used to calculate the cost as a whole and by sample.

 ## Precision and Sensitivity
 1. Use the GvsCalculatePrecisionAndSensitivity wdl to calculate the precision and sensitivity.

+The wdl takes several inputs as described below. Pro tip: it can be useful to look at the inputs from prior successful
+runs of the precision and sensitivity workflow *as a model* for new runs, being careful to update values as necessary.
+The inputs `sample_names`, `truth_vcfs`, `truth_vcf_indexes`, `truth_beds`, and `truth_fasta` are parallel arrays that
+should all be updated in lockstep with one another. `input_vcf_fofn` will need to be generated anew for every unique upstream
+run of `GvsExtractCallset`, while `chromosome` and `ref_fasta` will likely remain the same for every run.
 
-The wdl takes several inputs:
 
 **input_vcf_fofn** - A FOFN (file of file names) of output VCFs for control samples generated by `GvsExtractCallSet`. These need not be subsetted down to the chromosome.
 The FOFN should contain the full cloud paths to the VCFs, not just the file names.
