Evaluation - Quality Control (Exploratory Team Placement)

Problem statement

Identify samples of low quality (outliers) given gene expression data of case and control samples (input-qc.tsv).

You can assume this data set has been normalized and background corrected. Return a list of the low quality sample names.

*Disclaimer: The input data for this question was simulated. No disease-relevance can be obtained from this dataset.

Go to STEM-Away® Bioinformatics Evaluation - Quality control to get inputs and submit your answers.


  • This evaluation is mandatory for placement in Bioinformatics Exploratory Teams.

  • Students who are comfortable with the evaluations for Bioinformatics Power Teams may skip this evaluation.

  • Your first submission is the one that is graded. If you are not sure about the material, please wait until the corresponding training is held.

  • Highest level of academic integrity is expected from all members. Subtle changes are made in the test to discourage copying of answers. Submissions include inputs and results.
