PEA Calculator

Help

This tool analyzes the percent epitope accessibility (PEA) of a peptide vaccine candidate. Input a file, specify epitopes, and get results on accessibility percentages.

Instructions for PEA Calculation

  1. Upload the .rsa file generated from the NACCESS tool, which contains the solvent-accessible surface area data.
  2. Specify the number of epitopes you wish to analyze in the "Number of Epitopes" field.
  3. For each epitope, enter the residue range in the format "start-end" (e.g., 51-65) in the corresponding fields.
  4. Click on the "Calculate PEA" button to initiate the analysis.
  5. The tool will calculate the Percent Epitope Accessibility (PEA) by comparing the accessibility of residues within the specified epitope ranges.

Note: Ensure that the .rsa file is properly formatted with solvent-accessibility values for accurate results.
