##Metabolite Analysis (MA)

###Overview: MA uses both REST and web controllers. REST controllers exist to begin analysis, whereas the web controllers exist to display HTML results of the analysis.

Here is a breakdown of the expected interaction with the MA feature, as well as high level details of the business logic:

• On the front end, a user will fill out the form that contains important threshold values, among others.
• On form submit, the input file will be uploaded to S3, client-side, via the AWS JavaScript SDK.
• Once the input file is uploaded, a REST call is made to HTTP POST /analyze/metabolites/<token>, where <token> is a UUID retrieved from HTTP GET /analyze/token. This starts analysis.
• The server will run the appropriate R commands via Rserve, which leads to a certain number of files being generated to a predefined directory.
• The server will read in these files and store the results into the database.
• The REST call above returns some HTML to display to the user, either an error or success message with a link to the results page.
• The user navigates to the result page, and the web controller contacts the database for the computed results.
• The results are passed back to the front end, using Thymeleaf as the template engine.
• The JavaScript modules and libraries (D3.js) now do their work to initialize and bind the necessary events.
