Y-STR Mixture Calculation

Calculate the likelihood ratio of donorship of a given suspect versus non-donorship. The calculation requires a column named "Role" in your input file and consists of the following rows (specified at the "Role" column):

Trace: A trace (all given markers will be used for calculation)
Suspect: The profile of the suspect (or accused or defendant, or the profiles of the suspects if multiple)
Known Contributor: The profiles of additional known contributors (optional)

The only thing to enter after uploading your file is the number of unknown contributors.

Use the new hierarchical approach to evaluate Y-STR mixtures (thus take all subsequent-sized datasets into consideration - instead of just using the one your profiles where typed with).
