Table 2. Metadata table body.

Fields included in the body of the metadata table that describe the individual sequences included in the dataset. The required fields are biosample_acc, strain, and sra_acc. Any optional field can be blank or contain a dash (−) if no value is given. Field names are case insensitive.

Field	Description	Required	Example value(s)
biosample_acc	The identifier found in the NCBI BioSample database. This usually starts with SAMN or SAME.	Yes	SAMN01939119
Strain	The name of the isolate	Yes	CFSAN002349
genBankAssembly	The GenBank assembly identifier	No	GCA_001257675.1
SRArun_acc	The Sequence Read Archive identifier	Yes	SRR1206159
outbreak	If the isolate is associated with the outbreak or recall, list the PulseNet outbreak code, or other event identifier here.	No	1408MLGX6-3WGS outgroup
datasetname	To which dataset this isolate belongs	Yes	1408MLGX6-3WGS
suggestedReference	For reference-based pipelines, a dataset can suggest which reference assembly to use	Yes	TRUE FALSE
sha256sumAssembly	The sha256 checksum of the genome assembly. This will help assure that the download is successful.	Yes	9b926bc0adbea331a0a71f7bf18f6c7a62ebde7dd7a52fabe602ad8b00722c56
sha256sumRead1	The sha256 checksum of the forward read	Yes	c43c41991ad8ed40ffcebbde36dc9011f471dea643fc8f715621a2e336095bf5
sha256sumRead2	The sha256 checksum of the reverse read	Yes	4d12ed7e34b2456b8444dd71287cbb83b9c45bd18dc23627af0fbb6014ac0fca
