Example text

Bioinformatics projects contain many smaller analyses—for example, analyzing the quality of your raw sequences, the aligner output, and the final data that will produce figures and tables for a paper. I prefer keeping these in a separate analysis/ directory, as it allows collaborators to see these high-level analyses without having to dig deeper into subproject directories. 22 | Chapter 2: Setting Up and Managing a Bioinformatics Project What’s in a Name? Naming files and directories on a computer matters more than you might think.

Ly/htsmappers). Likewise, our approach to genome assembly has changed considerably in the past five years, as methods to assemble long sequences (such as overlap-layoutconsensus algorithms) were abandoned with the emergence of short high-throughput sequencing reads. Now, advances in sequencing chemistry are leading to longer sequencing read lengths and new algorithms are replacing others that were just a few years old. Unfortunately, this abundance and rapid development of bioinformatics tools has serious downsides.

We’ll see examples of this in Chapter 2. Make Assertions and Be Loud, in Code and in Your Methods When we write code, we tend to have implicit assumptions about our data. For exam‐ ple, we expect that there are only three DNA strands options (forward, reverse, and unknown), that the start position of a gene is less than the end position, and that we can’t have negative positions. These implicit assumptions we make about data impact how we write code; for example, we may not think to handle a certain situation in code if we assume it won’t occur.
