The QA team member is the link between the Coder/Designer and the Data Analyst. He or she needs to know the details of the microarray dataset being analyzed so that the database being designed and populated by the Coder/Designer is correct and useful for the Data Analyst. The QA also makes sure that the data analysis steps are being performed correctly and are being correctly documented.

Milestones

The milestones do not necessarily correspond to particular weeks; instead they are sets of tasks grouped together.

• QA's can have a shared individual journal entry. Both students will be given the same grade and are expected to contribute equally to the electronic lab notebook.
• Detailed notes should be taken throughout consistent with reproducible research and contributing to the final deliverables.

Milestone 1: Journal Club Presentation

• The QA's will work with their teams to create and deliver a Journal Club presentation about to their team's assigned paper.

Milestone 2: Working with Data Analysts to understand microarray dataset

As an overview, the QA team members are the link between the Coder/Designer and the Data Analyst. He or she needs to know the details of the microarray dataset being analyzed so that the database being designed and populated by the Coder/Designer is correct and useful for the Data Analysts. The QA's will independently check that all of the data retrieved from SGD is present and accurately represented in the MS Access database. The QA will also provide assistance to the Data Analysts, making sure that the data analysis steps are being performed correctly and are being correctly documented.

1. Download and examine the microarray dataset, comparing it to the samples and experiment described in your journal club article.
   • Link to processed dataset from SGD.
   • For your reference, this is the link to the dataset at the GEO Database:GSE26169. However, we will use the dataset processed by SGD.
2. Along with the QA's, make a "sample-data relationship table" that lists all of the samples (microarray chips), noting the treatment, time point, and replicate number.
3. Report on these quality measures:
   • Are all the samples described in the paper in the dataset?
   • Are all the samples in the dataset described in the paper?
4. Come up with consistent column headers that summarize this information
   • For example, the Dahlquist Lab microarray data used strain_LogFC_timepoint-replicate number, as in wt_LogFC_t15-1.
   • Do not use any special characters except for "-" or "_" (e.g., no commas, etc.)
5. Organize the data in a worksheet in an Excel workbook so that:
   • ID (SGD systematic name) is in the first column
   • Data columns are to the right, in increasing chronological order, using the column header pattern you created
   • Treatments are grouped together
   • Replicates are grouped together
6. This information needs to be relayed to the Coder/Designers so that they can design an appropriate expression table.

Milestone 3: Making sure expression data has both Sytematic Name and Standard Name ID's

• The design of the expression tables in the final database will need both an ID field (yeast systematic name) and Standard Name fields.
• You will need to check the IDs in the expression data and potentially populate one or both of these fields.
• One way to do this is use the "ORF List <-> Gene List" tool at YEASTRACT.
• The Synergizer website may also be helpful.

Milestone 3: Design a database to store data needed to create a GRNmap input workbook

• Designer/Coders will work with the QA's to create a MS Access Database that will contain data needed to create a GRNmap input workbook.
  • Databases created by the teams will be kept in a "BIOL367_Spring2024" Box folder.
  • Coder/Designer guild members have rights as editor to this folder; all others in the class can only view/download.
  • This folder will serve as as the version control mechanism for the Coder/Designer guild.
• The database will need to have the following tables:
  • A gene table that contains all of the gene IDs for the entire yeast genome, obtained from YeastMine.
  • An expression table to store the yeast time-course microarray data for the dataset being analyzed by the Data Analysts. You will consult with the Data Analysts and QA's to figure out the sample-data relationships and how that should be encoded as fields in the database.
  • A degradation_rates table that contains degradation rates from Neymotin et al. (2014). This table will be provided.
  • A production_rates table that contains initial guesses for the production rates for each gene. This table will be provided.
  • A network table that contains the gene regulatory network data from the Harbison et al. (2004) paper.
  • A metadata table that encodes information about the database itself, i.e., other tables in the database.
    • A major part of the design work will be to figure out what information needs to be in the metadata table so that queries can be easily and uniquely performed on the data.

Milestone 5: Validation and Quality Assurance on Database

• After the Access database is built by the Coder/Designer, the QA will perform quality assurance to make sure that the database is correct and accurate.
  • In particular, the QA needs to make sure that all of the rows of data were imported into the database for the expression table(s).
  • The QA will make sure that both the ID (SGD systematic name) and Standard Names are included in each expression table and are correct.
• QA's will communicate to the Coder/Designers any changes needed to the database.

Milestone 6: Final Documentation

• With the Coder/Designer, finalize the database schema diagram
