Week 7: Matrix Files

This week, I’ve been creating a tabular file with all TCGA-COAD samples at the top of the file as column names, with genes at the sides. I should have a 512 x 60484 matrix file when done. However, with Sol’s help I realized that the file I initially output was actually 512 samples at the top, with only 443 columns after, but still with 60484 lines to the file.

Therefore, I think there’s something wrong in how I’m categorizing/organizing the samples.
