You can upload your population in jinkō with two different formats (JSON and CSV). This can be done using the create VPOP feature

Requirements

In both cases (JSON  and CSV), you need the following information per patient:

• A patientIndex: Text - a unique value identifying the patient

• A set of patientAttributes where each attribute has:

  • An identifier

  • A value

  • An optional unit

This translates as follows for each format:

CSV format

The separator is the standard comma: “,”

The header follows the pattern patientIndex,id₁(unit₁), id₂, ..., id_n(unit_n) . The unit can be specified in brackets (unit) after the id. In this example id₂ does not have a unit specified

Body follows the following pattern: patient₁, val¹₁, val¹₂, ..., val¹_n 

• patientIndex column: Text, should be unique for each row

• Patient descriptors columns: Float is mandatory

Example (presented in tabular format for readability):

JSON format

The virtual population object is a list of patients

Each Patient has:

• A "patientIndex": Text

• A "patientAttributes": Object

  • "id": Text

  • "val": Float

  • "unit": Text (optional)

Example:

{
    "patients": [{
            "patientIndex": "patient1",
            "patientAttributes": [{
                    "id": "age",
                    "val": 60.7,
                    "unit": "year"
                },
                {
                    "id": "sizeHelper",
                    "val": 0.294,
                    "unit": "dimensionless"
                },
                {
                    "id": "isMale",
                    "val": 1,
                    "unit": "dimensionless"
                }
            ],
            "patientIndex": "patient1"
        },
        {
            "patientIndex": "patient2",
            "patientAttributes": [{
                    "id": "age",
                    "val": 55.2,
                    "unit": "year"
                },
                {
                    "id": "sizeHelper",
                    "val": 0.407,
                    "unit": "dimensionless"
                },
                {
                    "id": "isMale",
                    "val": 0,
                    "unit": "dimensionless"
                }
            ]

        },
        {
            "patientIndex": "patient3",
            "patientAttributes": [{
                    "id": "age",
                    "val": 70.3,
                    "unit": "year"
                },
                {
                    "id": "sizeHelper",
                    "val": 0.822,
                    "unit": "dimensionless"
                },
                {
                    "id": "isMale",
                    "val": 0,
                    "unit": "dimensionless"
                }
            ]

        }
    ]
}

A note on Units

The base units used in the platform are:

•  [length]              :  "meter   = m  = metre"

•  [time]                 : "second  = s    = sec"

•  [current]            : "ampere = A   = amp"

•  [luminosity]      : "candela = cd = candle"

•  [mass]               : "gram     = g"

•  [substance]      : "mole      = mol"

•  [temperature ] : "degK      = K  = kelvin"

•  []                        : "dimensionless”

You can use prefix in the units combination, below is a non-exhaustive of accepted prefix:

• "nano-  = 1e-9  = n-"

• "micro- = 1e-6  = u-"

• "milli-    = 1e-3  = m-"

• "centi-   = 1e-2  = c-"

• "deci-    = 1e-1  = d-"

• "deca-   = 1e+1 = da-"

• "hecto-  = 1e2   = h-"

• "kilo-      = 1e3   = k-"

• "mega-  = 1e6   = M-"

• "giga-    = 1e9   = G-"

You can combine and exponent units as follow:  kilogram * meter / second ** 2
