Bioinformatics

Is there a place for citizen scientists in the world of digital biology? Many of the citizen science projects that I’ve been reading about have a common structure. There’s a University lab at the top, outreach educators in the middle, and a group of citizens out in the field collecting data. After the data are…

These days, DNA sequencing happens in one of three ways. In the early days of DNA sequencing (like the 80’s), labs prepared their own samples, sequenced those samples, and analyzed their results. Some labs still do this. Then, in the 90’s, genome centers came along. Genome centers are like giant factories that manufacture sequence data.…

What do you call a biologist who uses bioinformatics tools to do research, but doesn’t program? You don’t know? Neither does anyone else.

I often get questions about bioinformatics, bioinformatics jobs and career paths. Most of the questions reflect a general sense of confusion between creating bioinformatics resources and using them. Bioinformatics is unique in this sense. No one confuses writing a package like Photoshop with being a photographer, yet for some odd reason, people seem to expect…

For many years, I’ve been perfectly content to work with small numbers of things. Working with one gene or one protein is great. Even small groups of genes are okay. I’m fine with alternatively spliced genes with multiple transcripts, or multiple polymorphisms, or genes in multi-gene families, or groups of genes in operons. But I…

For those of you who may have been wondering where I’ve been, these past few weeks have seen me grading final projects, writing a chapter on analyzing Next Gen DNA sequencing data for the Current Protocols series, and flying back and forth between Seattle and various meetings elsewhere in the U.S. It will probably take…

No more delays! BLAST away!

We’ll have a blast, I promise! But there’s one little thing we need to discuss first…

We had a great discussion in the comments yesterday after I published my NJ trees from some of the flu sequences. If I list all the wonderful pieces of advice that readers shared, I wouldn’t have any time to do the searches, but there are a few that I want to mention before getting down…

What tells us that this new form of H1N1 is swine flu and not regular old human flu or avian flu? If we had a lab, we might use antibodies, but when you’re a digital biologist, you use a computer. Activity 4. Picking influenza sequences and comparing them with phylogenetic trees
