Remove exercise from 02 Assessing Read Quality

This exercise isn't really relevant at this point in the episode and should probably be replaced with something else.

How big are the files? (Hint: Look at the options for the ls command to see how to show file sizes.)

Hi @ErinBecker, I recently completed my Instructor Training and I am looking for issues that need to be fixed. I can still see the size exercise in 02 Assessing Read Quality. I usually check file sizes all the time just to make sure that I am getting actual outputs at every step of the process, so I would keep this exercise with a brief explanation of why should file sizes be checked and how to interpret the answer: is it the size range of 124M (124MB) to 545M often observed for this type of data? What is the expectation? etc.

What is the status of the lesson? Do you still need a hand with this issue?

Hi @vhmcck, I just wanted to chime in here that I am no longer up to date on the status of these lessons and so if you feel that this exercise is relevant at that point in the lesson, then I think that's an argument in favor of keeping it! This issue was one of many when we were trying to update the lessons from single end to paired end reads, among other changes. This change didn't end up making it in to that update though.

Thanks, @taylorreiter. I just submitted a PR with some changes to this episode, including a justification of the file size check exercise: https://github.com/datacarpentry/wrangling-genomics/pull/235#issue-1459300919
