Genome 373: Genomic Informatics

   Elhanan Borenstein, elbo [ a t ]

Teaching Assistant:

Schedule: MWF, 10:30-11:20, Hitchcock 220.


This course is intended to introduce students to the breadth of problems and methods in computational analysis of genomes, arguably the single most important new area in biological research. The specific subjects will include large-scale comparative genome structure, sequence alignment and search methods, gene prediction, evolutionary relationships among genes, and next-generation sequencing. The course will include one mid-term exam and a final exam. Other graded assignments will be problem sets, due most weeks. Some problems will include computer programming and most will involve extensive use of web resources for data set mining.


» Midterm: Friday, May 3, 2013. *** Note, you are allowed to bring a two-sided cheat sheet ***
» Problem Set 4 is now posted below.
» The class has filled up and we have a wait-list. If you are on the wait-list, we suggest that you come to the first day of class. Although we are not planning on expanding the class past the current count, based on our past experience there are often several individuals who drop, such that we may be able to accomodate a subset (or, ideally, all) of the wait list.

Test/Demo Files

The following files may be used in some of the in-class exercises and demos or in the home assignments.

Python Resources:

Regular Expressions
"RegExPal" (For Javascript rather than Python, but similar and quite handy. Try it!)
Python Books
Python for Software Design: How to Think Like a Computer Scientist by Allen B. Downey. (Includes early drafts of our text book; cheaper than the published version, but less polished...)
Learning Python by Mark Lutz. O'Reilly (Very comprehensive. Much is accessible to beginners.)
Dive Into Python 3 by Mark Pilgrim. (Another online book. Based on Python 3, so some differences, and more advanced, but also free.)

Bioinformatics Books

» Biological sequence analysis: probabilistic models of proteins and nucleic acids, R. Durbin, S. Eddy, A. Krogh, and G. Mitchison, Cambridge. (Excellent reference, classics)
» Inferring Phylogenies, Joseph Felsenstein, Sinauer, 2004. (Excellent reference on this topic.)
» Introduction to Computational Genomics: A Case Studies Approach, Cristianini, Nello & Hahn, Matthew, Cambridge, 2007.
» An Introduction to Bioinformatics Algorithms, Neil C. Jones & Pavel A. Pevzner, 2004.
» Bioinformatics: Sequence and Genome Analysis, David W. Mount, Cold Spring Harbor Laboratory Press.
» Python for Bioinformatics, Sebastian Bassi, CRC Press, 2010. (A little too advanced as a progamming book for beginners, but fine now that you're experienced.)
» Python for Bioinformatics, Jason Kinser, Jones and Bartlett, 2009. (Ditto.)
