    CDD Vault Update (July 2025): Custom Axis Scaling, AUC Fold Change, Copy Reactions and Stoichiometry Tables, and Sample Tracking Improvements for the ELN

    Custom Axis Scaling

    Setting a custom axis range in a plot allows you to manually define the minimum and maximum values for both the x- and y-axes. Instead of relying on the plotting library to automatically scale the axes based on your data, explicitly set the range for a protocol. Setting the axis ranges can help to focus the plot on a specific data region, keep consistency across all plots, and improve readability. 

    Toggle the scale for either axis to a logarithmic scale to create a fully logarithmic plot or semi-logarithmic plot. Plotting data on a logarithmic is particularly useful for data that has an exponential decay as it linearizes the curve fit making it easier to interpret differences between data points. Using a logarithmic scale aids in visualizing data sets that have a wide data range of values. For pharmacokinetic data, the plot is able to separate small and large concentrations clearly to facilitate comparing different sets of data.

    Area Under the Curve (AUC) Fold Change: 

    Calculate a fold change for area under the curve calculations when plotting a reference molecule alongside a test compound. Display the AUC Fold change by using “Customize your report” and selecting the field. 


    AUC Fold Change is calculated for all curve fits. This new value can be calculated for existing data by retriggering calculations within the protocol details

     

    Copy Reactions and Stoichiometry Tables:

    Easily duplicate a reaction setup on the same ELN page. Hover over the reaction scheme and click the copy icon. Paste your reaction scheme further down the page or on a new ELN page using ctrl+v on your keyboard. 

    Sample Tracking Improvements for the ELN:

    Specific samples registered to the inventory can now be referenced in the body of an ELN entry and now within a stoichiometry table. The reagent or product sample must be registered in the inventory first. Then, click into the stoichiometry to edit, and click the compound ID to associate the row with a specific sample ID. After associating the sample ID, a test tube icon will appear that, when clicked, will allow a user to debit an amount from the inventory and fill in other Inventory meta data fields directly from the stoichiometry table.
