        Flux Variability Analysis (FVA)

        This tool performs Flux Variability Analysis (FVA) on a Genome-scale Metabolic Model (GEM). FVA is a method used to determine the minimum and maximum flux values that each reaction in the network can carry while maintaining a specific objective value.

        Input Parameters

        **Model File**: A GEM in SBML format (.xml) that will be analyzed.

        **Fraction of Optimum**: A value between 0 and 1 that determines how much the objective function can deviate from its optimal value. For example:
        - 1.0: Only solutions achieving 100% of optimal objective value
        - 0.9: Solutions achieving at least 90% of optimal objective value
        - 0.5: Solutions achieving at least 50% of optimal objective value

        **Uptake Constraints File** (optional): A CSV file specifying constraints for exchange reactions. The file should contain columns for exchange reaction IDs and their corresponding bounds.

        Output
        
        The tool generates a CSV file containing:
        - Reaction IDs
        - Minimum flux values
        - Maximum flux values
        for each reaction in the model.

        Common Issues
        
        - Ensure your model is well-formatted and contains no structural errors
        - Check that exchange reactions are properly defined
        - Verify that the model is feasible under the given constraints
        - Large models may require significant computation time
