Why are some of the menu items missing from my PV Loop Menu?

With the PV Loop 2.0 analysis module, there is a useful workflow tool that can be used to guide you through the steps of your pressure-volume calibration and analysis. This makes menu items and tool bar icons available when logical steps have been completed.

It is not essential to use the workflow and if your data is precalibrated, you may wish to disable this option. In order that all the menu items are available to you, you will need to select 'workflow mode....' from the PV Loop menu and uncheck the box.
