- TCGA_PAAD_plus.RData contains 181 PDAC patient samples of RNA-seq data.
- ex: unlogged TPM values; sampInfo: sample information; featInfo: gene information.
- Please only consider 150 samples with non-NA sample information in the Grade column for all the analysis.
- Please submit the code for analysis and result figures.
- Please push your results as a separate folder with your name to this same repo.

Q1: Perform a consensus clustering for 150 samples using genes in Moffitt-basal25.txt (orange) and Moffitt-classical25.txt (blue). Use K=2 for both column and row. Plot a heatmap to show the result. The resultant two clusters of samples are basal-like (orange) and classical (blue) subtypes respectively. 

Q2: Test if each of the genes in AURKA_sig_genes.txt is differentially expressed between basal-like and classical subtypes. Use boxplot to illustrate the results with p-values labeled on the figures.

Q3: Identify all the differentially expressed (DE) genes between basal-like and classical samples using DESeq2 (http://bioconductor.org/packages/devel/bioc/vignettes/DESeq2/inst/doc/DESeq2.html). Plot MA plot and volcano plot to show the results. Cut-offs to use: p=0.05, log2(fold-change)=1. Read counts are in file TCGA_PAAD_plus.cnt.txt.gz. Patterns of sample ID need to be used to match to samples in .RData.

Q4: Is subtype assocaited with the clinical variables (sex, age, gender and race)? Use a table with p-values to show the results.

Q5: Provide the script/pipeline you used to process raw RNA-seq data (.bcl) with clear annotation for each step.
