Extra seeds files
This file specifies how infections should be seeded in an outbreak. This is a column-based flexible-format file, with each line of the file containing information about a specific seeding event.
There should be up to three pieces of information per line;
day: The day or date to seed the infection(s). This should be an integer or a date that is interpreted via
Interpret.day_or_datefunction. This either sets the day number on which to seed, or the exact date in which to seed.
ward: The ward (either index or name) in which the infection will be seeded. This should either be an integer (whole number) specifying the index of the ward (1-indexed), or a string that identifies the ward by name, e.g.
Clifton/Bristolwould look for the ward called
Cliftonin the authority
Bristol. The ward is looked up by name using the
number: The number of infections to be seeded. This is an integer that is interpreted via the
demographic(optional) : The demographic (either index or name) in which the infection will be seeded. If this is not specified, then the first demographic in the network is seeded. If this is the index it is interpreted via
Interpret.integer, while if this is the name then this will direct look-up the demographic by name.
This is a column-formatted file. Like all flexible-format files you can use
commas or spaces to separate columns. The separators used in the first line
will be assumed to be used for the rest of the file. You can order the
columns however you wish, as long as you provide column headers
number, and (optionally)
the column orders are
You can add extra spaces and blank lines to make the file more readable,
and can add comments via the
1 5 1
Seed 5 infections on day 1 (first day) of the outbreak in ward 1.
1, 5, 1
Same, but using commas to separate
day, ward, number # seed 5 infections on day 1 in ward 1 1, 5, 1
Same, but naming the columns and adding a comment
# Seeding two locations in Bristol day, demographic, ward, number tomorrow, 0, Clifton / Bristol, "rand(5, 20)" next week, 0, Knowle / Bristol, 5 + 3
Adding comments and changing the order of columns. Seeding by fuzzy dates,
next week in wards identified by
name / authority. Number to be seeded is a random number from 5 to 20
(inclusive) in Clifton, Bristol, and the result of the expression
5 + 3 (8) in Knowle.
