1. When using this option you will be limited to 50k iterations. This option places significant burden on the server - make sure your choices are well considered!!!

2. Set up the calibration and model above as normal - ensure you have data set for both calibration and validation.

3. Any preprocessing you set up will be applied to the spectra before optimisation - do not include things that iwll be repeated in the iteration.

4. Set the variables you would like to explore as comma separated - examples are provided as defaults.

5. Enter the password - this requires server time so is a limited feature.

6. Press go and wait.
