Representations and associated fitness values of protein sequences

We studied the ability to predict protein fitness from sequence using our method MERGE and other methods (i.e., ECNet, eUniRep, EVmutation, One-Hot, and UniRep). The following files are included in this repository: The folder ECNet contains the braw, csv, and fasta files required to run ECNet. The folders eUniRep, MERGE, One-Hot, and UniRep contain csv files including the names and fitness values of protein variants as well as a numerical representation of their sequence. The folder MERGE also contains representations of the wild type sequences as npy files in the wts folder. The folder Params contains params files generated with PLMC. The script get_performances.py enables to generate models using different methods (i.e., eUniRep, EVmutation, MERGE, One-Hot, Pure_ML, and UniRep) and to determine their performance for predicting the fitness of protein variants from sequence.
