We teach a course called “Computational Genetics” each year at UCLA. This course is taken by both graduate and undergraduate students from both the Computer Science department and the many biology and medical school programs. In this course we cover both topics related to genome wide association studies (GWAS) and topics related to next generation sequencing studies. One lecture that is given each year is an introductory lecture to sequencing and read mapping. The video of this lecture is available here. Please excuse the poor cinematography. This lecture was recorded from the back of the classroom.
