 ## Nelle's Pipeline: A Typical Problem
 
-Nelle Nemo, a marine biologist,
-has just returned from a six-month survey of the
-[North Pacific Gyre](http://en.wikipedia.org/wiki/North_Pacific_Gyre),
-where she has been sampling gelatinous marine life in the
-[Great Pacific Garbage Patch](http://en.wikipedia.org/wiki/Great_Pacific_Garbage_Patch).
-She has 1520 samples that she's run through an assay machine to measure the relative abundance
-of 300 proteins.
-She needs to run these 1520 files through an imaginary program called `goostats.sh` she inherited.
-On top of this huge task, she has to write up results by the end of the month so her paper
-can appear in a special issue of *Aquatic Goo Letters*.
-
-The bad news is that if she has to run `goostats.sh` by hand using a GUI,
-she'll have to select and open a file 1520 times.
-If `goostats.sh` takes 30 seconds to run each file, the whole process will take more than 12 hours
-of Nelle's attention.
-With the shell, Nelle can instead assign her computer this mundane task while she focuses
-her attention on writing her paper.
-
-The next few lessons will explore the ways Nelle can achieve this.

+Phillipa Frogg, an ecologist, wants to use the [Living Planet Index dataset](https://www.livingplanetindex.org/)
+to help her with her research. However, she is unable to use the raw data directly; instead, she has to
+edit the data so it's in a suitable format for her to make best use of. Although she could do this by hand in
+a text editor, this would be laborious, time-consuming, and error-prone. With the shell, Phillipa can instead assign her computer this mundane task while she focuses

 As a bonus,
 once she has put a processing pipeline together,
 she will be able to use it again whenever she collects more data.
