    2. For each input point, define clear validation rules based on expected data types, formats, ranges, and allowed characters within the Nextflow workflow context.
    3. Implement input validation steps at the beginning of the workflow, before any data processing occurs within Nextflow processes. Use Nextflow's scripting capabilities (e.g., Groovy, Python within processes) to perform validation as part of the Nextflow workflow definition.
    4. If input data fails validation, halt workflow execution immediately via Nextflow error handling and provide informative error messages to the user through Nextflow's reporting mechanisms.
    5. Implement input sanitization within Nextflow processes to neutralize potentially harmful characters or code within inputs. This might involve escaping special characters, removing disallowed characters, or encoding data using Nextflow scripting capabilities.
    6. Log all input validation and sanitization activities within Nextflow workflows for auditing and debugging purposes, leveraging Nextflow's logging features.

    3. Implement output sanitization at the end of each process, before sending data to output channels. Sanitize process outputs to remove any potentially harmful or unexpected data.
    4. Log any validation failures or sanitization actions within the process execution logs for debugging and auditing.
