Computational pipelines: to build and maintain them

Pipelines are basically a series of data analysis steps rendered computationally. I sat down, virtually that is, with two scientists at DNAnexus to talk about some ways to build and maintain pipelines. Episode art: Justin Jackson
Pipelines are basically a series of steps. Algorithms are linked to one another, the output of one algorithm is the input to another. 
Pipelines can be simple and pretty complex. And maintenance of pipelines also ranges from simple to complex. They can run like a dream, they can get stuck, they can break. To talk about trends in this area, I sat down, virtually that is, with two scientists at DNAnexus: John Ellithorpe who is DNAnexus executive vice president and chief product officer and George Asimenos chief technology officer at DNAnexus.
