Table 3.

A qualitative description of the computational costs of the analyses performed.

Task Relative memory usage Timescale
ORA Low Seconds
GSEA Medium Minutes
ssGSEA Very high Hours
Prediction of tumor vs. normal Medium Minutes
Prediction of known tumor subtype Medium Minutes
Prediction of overall survival Medium Hours

Performing ssGSEA required on the scale of 100 GB of RAM for some dataset/database combinations, while the other tasks could be run on a modern laptop with no issues.
