@reednel If you have time to review, please do! It is not urgent, so don't prioritize this right now. I will take a look early January.

Will test it on the server and push a new version after the testing.

Hey Sophia, great work and sorry for the delay. I have just a few comments for you.

1. Please update the Copyright year at README.md:19, LICENCE:3, and aboutTab.R:122.
2. In the DESCRIPTION file, set the author to yourself or Claudia. I assume it's just a web metadata thing but still this webapp is not mine to claim authorship of. And I'd recommend setting the version to 1.0.0 now, and applying a release tag of v1.0.0 to the suitable commit in Github later.
3. If I'm correct in the observation that merge.R and visualize.R are not being used at all, they can be deleted. Should the need arise later, there's always the git history.
4. Please update the README.md with something like a Development Instructions section describing how to get started with a local instance of the app.
   • Need R Studio...R version x.y.z...run [this] code [here] to install the requisite packages...etc.
   • Related side note: tonight I tried to run a local build of the app, and got the error there is no package called ‘shinyWidgets’. I haven't touched R in a couple years so after install.packages("Shinywidget") failed citing an unsupported version of R, I just gave up on an inspection of the UI.
5. The following is just a code aesthetic thing, but in each of aboutTab.R, alignTab.R, resultTab.R, and visualizeTab.R, you define some CSS classes at the top. I believe it would be better practice to define all of those in a single style file and import that to each of these tabs, but I'm not sure if Shiny permits such a thing. In any case, this only impacts 4 files, you'll get my approval whether or not you address that.

@reednel Can you review this at your convenience?

@Sophiayangg For #4, you can use this readme as a template: https://github.com/solislemuslab/bioklustering

I'd like to see the README made more developer-friendly but otherwise I think it's great. I look forward to seeing this app up on wid.wisc.edu
