  • It is a requirement that participants join Zoom for this training via computer audio and video (not via telephone)

Workshop price: EUR 1,740 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), with a companion text which describes in detail the mathematics and biology behind STRmix™, the database search and model maker functions
  • 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 supplementary training modules about Population Genetic Models and Likelihood Ratios via the Talent LMS e-learning platform ( link)).  These will remain available for a limited period after the workshop.  For best results, please complete these modules prior to the training.

STRmix™ Evaluation version installation: This will be a remote installation of STRmix™ approximately a week before the start of the workshop.  Please follow the Test your STRmix™ run online training module to confirm successful operation of the software prior to the start of the workshop.  A laptop is required during the workshop and the specifications are as follows:
