Transformer-DIA usage

Step 0: Data Preparation

• Split each dataset into train set, validation set, and test set
• Annotate the spectra file with the corresponding label extracted from feature file
• Create a new feature file

Step 1: Run de novo sequencing with a pre-trained model:

Step 2: Evaluate de novo sequencing results:

Step 3: Train a new model:
