You can review all processing that has been performed on a loaded trial file on the History tab in the Communications pane. This ensures that, even if you have not worked with the data before, you can work on the trial without missing or duplicating processing steps. For example, if you work as part of group, when you open a trial that someone else has worked on, you can immediately see what processing has occurred (eg, filtering, gap-filling) and what settings were used.

Being able to view processing history helps you to understand your data, prevents errors introduced by running certain operations more than once (eg, filtering), and reduces the need to reprocess data because its current state is not well known.

Note
Processing history is available only for files processed in Nexus 2.3 and later.

To view processing history:

Open a trial.
In the Communications pane, click the History tab.
A summary of the data processes and major events is displayed.
To display information about a particular event, click the event.
Details about the settings used to run the event are displayed in the Property and Value columns on the right.
In the Notes field, you can add notes that will be useful to you or anyone else working with the same trial. Your notes are saved with the trial.
