Overlap: The laboratory section of ECS 124 will overlap to some amount with Animal Genetics 212 (taught by J. Medrano) a graduate course offered every other year. The overlap in the laboratory section is only partial, as ANG 212 looks at more sequence analysis packages than in ECS 124; the lab portions of ECS 124 also look at packages for cluster enrichment, biological networks and phylogenetic analysis, which are not covered in ANG 212. They also involve computer programming in Perl or Java, while no programming is involved in ANG 212. The theoretical parts of ECS 124 (the lecture part of the course) will have no essential intersection with ANG 212, being either on different material entirely, or being a much more mathematical and algorithmic treatment of the material, i.e., fully explaining and developing the logic of the techniques, rather than focusing on learning to use these techniques in the form of packaged computer programs. A good analogy to explain the partial intersection is that ANG 212 is a course on “flying an airplane” while ECS 124 will be on the “physics of flight” with exercises in flying to make the ideas concrete.
ECS 124 intersects with ECS 221 (taught by I. Tagkopoulos), a graduate seminar course which focuses on Machine Learning methods in Systems and Synthetic Biology. The overlap is mainly on the areas of clustering, classifications and network analysis. ECS 221 assumes advanced computer science knowledge and treats these topics with more mathematical rigor than ECS 124, which includes lectures related to fundamental computer science methods (e.g. suffix trees, dynamic programming, etc.). In contrast to ECS 124, ECS 221 focuses on the presentation of research papers in the field, while it does not requires any laboratories/homeworks.
ECS 124 intersects EVE 298 (taught by M. Sanderson and S. Nadler) in the subarea of phylogenetics. However, the emphasis of the two courses in that overlapping subarea is again different. EVE 298 is oriented towards teaching biology graduate students to use computerized phylogenetic tools effectively in their biological (phylogenetic) research, while ECS 124 will have a more algorithmic and mathematical orientation.
ECS 124 intersects GGG 298D (taught by C. Warden and M. Syvanen) in the subarea of sequence analysis. Again the emphasis is quite different. GGG 298D is oriented towards teaching biology graduate students to use computerized sequence analysis tools effectively in their (biological sequence analysis) research, while ECS 124 will have a more algorithmic and mathematical orientation. There are no undergraduate courses on campus that have any substantial intersection with ECS 124.
Instructors: D. Gusfield and I. Tagkopoulos
History: 2012.10.29 (I. Tagkopoulos): Expansion of syllabus to include genome assembly and current methods in sequence mapping. Addition of a section related to computational methods in Systems Biology (Biological Networks, Machine Learning in Biology). Protein structure prediction methods where removed from the syllabus as there is an overlap with ECS 129. Addition of overlap explanation with ECS 221. Prior version by D. Gusfield, Oct 2006.
