 ## Computational performances
 
 We measured the efficiency of data generation in DeepRank2 using the tutorials' [PDB files](https://zenodo.org/record/8187806) (~100 data points per data set), averaging the results run on Apple M1 Pro, using a single CPU.
-Parameter settings were: atomic resolution, `distance_cutoff` of 5.5 Å, radius (for SRV only) of 10 Å. The [features modules](https://deeprank2.readthedocs.io/en/latest/features.html) used were `components`, `contact`, `exposure`, `irc`, `secondary_structure`, `surfacearea`, for a total of 33 features for PPIs and 26 for SRVs.
