#@deckyard/strider

Reads a STRidER STR allele-frequency export in XML and converts one population of it into the FrequencyDb that @deckyard/forensicgenetics computes with.

This deck is part of Deckyard, community decks for Jennifer.

import "@deckyard/strider/" as strider;
import "@deckyard/forensicgenetics/" as forensics;

def t as strider.Table init strider.parse($xml);
strider.populations($t);   # the whole database, each continent, each country

def db as forensics.FrequencyDb init
    strider.toFrequencyDb($t, "AUSTRIA", "STRidER AT");

The forensicgenetics core defines FrequencyDb and reads no published format. This deck converts one source into it; the core does not import it, so a reader for another source can sit beside it without touching the estimators.

The deck does not:

• fetch anything: you pass the document text
• bundle real data: STRidER's terms forbid redistribution, see Reading a table
• combine populations: that operates on FrequencyDb values and lives in the core, see Choosing a dataset
• apply a frequency floor: forensics.alleleFrequency does that on read
