Workshop price$US 2,000 per participant

Overview:  This workshop will provide participants with extensive and full STRmix™ user training, covering likelihood ratios and sampling uncertainty, introduction to STRmix™, and a detailed description of the molecular models and mathematics on which STRmix™ is based.  Also included are ample “hands on” sessions to allow participants to use and familiarise themselves with STRmix™ under the guidance of the instructors.

 Participants will also receive:

  • the STRmix™ User’s manual (electronic PDF)
  • the STRmix™ Operation Manual and STRmix™ Implementation and Validation guide (electronic PDF)
