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)
  • a 2-month evaluation version of STRmix™
  • electronic copies of training material (for download prior to the training)
  • a certificate of attendance (after completion).

Online training modules:  Prior to the training, participants will be provided with online access to an introductory training module via the Talent LMS e-learning platform ( link)).  For best results, please complete this prior to the training.

Supplementary training modules covering topics such as Population Genetic Models and the use of Replicates and Multi-kits will also be provided for a limited period via the same platform.
