Seeq R21 is a combination of ease of use features, improved analytical tools, and user requested features.

The big changes in R21 include an updated user interface (UI), frequency analysis with Fast Fourier Transform (FFT) with the new Frequency Analysis tool, new formulas, and new functions.

Ease of Use

Expanded Color Palette

Quickly identify Workbench Analysis (green) and Organizer Topic (blue) with new color scheme.

Quickly focus on specific data

Enable Show only selected items from the Dimming dropdown on the toolbar of any Workbench Analysis to trend only items selected in the Details Pane. When this is not selected, previous signal dimming remains.

Multicolumn Scorecard Metrics

Create multicolumn tables with Scorecard Metric with each column based on a capsule or particular time range within the display range. Thresholds can be signals or strings, and will display boundaries along with the signal of interest when the scorecard is viewed in the trend viewer. Read more on configuring the flexibility this tool provides here.

Change Workbook Ownership

Users can now assign a workbook to another person when they shift roles.

Change Workbook Ownership


Quickly note what folder work is stored in, or jump to a parent folder with links at the top of the header section of the screen. Right click on these to open the parent folder in a new tab!


Investigate range update

The capsule preview in the investigate range now defaults to OFF. You can turn it back on when you want to have that functionality with the button to the right of the investigation range. Leaving this off can reduce calculation time to load the worksheet.

Improved Analytical Tools

Frequency Analysis Tool

Users can now perform frequency analysis on signals with Fast Fourier Transform (FFT) with the new Frequency Analysis tool. Read more on the tool here.

Correlation function

New formula function correlationOffset() improves regression analyses with time-delay impacts. Using this formula first will identify time delay between two signals and shift one so that the correlation is maximized in subsequent regression analysis.

As an example, Signals 1 and 2 (shown at right) are highly correlated but Signal 1 leads Signal 2. As a result, the strong correlation is not evident in a scatter plot. Signal 1 can be aligned with Signal 2 using the correlationOffset() function, which identifies the positive or negative offset (time shift) needed to maximize correlation. The offset value is then used by the delay() function to create a new aligned signal. The Formula for this example is shown below:

Formula Block

Note that the offset time (a negative value when shifting the signal to the left on the time axis) can be returned from the formula and used in other calculations.

This new functionality can be useful in many ways, including alignment of product quality data and analyzing cause/effect relationships between signals in different processing sections.

Histograms for Conditions

Conditions can now be used as inputs into histograms, enabling counting of batches and summing of durations during other other conditions.

Other new functions

timeSince() Users can use this function to assist with modeling fouling or activity decay with respect to time. A long formula block could achieve this in R20 and prior, but the new timeSince() function makes it so much easier
replace() Replace string values in a signal with another string. Maybe whenever your compressor is in "Stage 1" or "Stage 2", you just want the signal to show "ON". This function supports regular expression searches.
isValid() & isNotValid() Streamline the discovery of periods of invalidity using ValueSearch() in formula, along with the new isValid() and isNotValid() functions.
sin(), cos(), tan(), asin(), acos(), atan() New support for trigonometry functions
agileFilter() Smooth a signal using the Loess method, also known as Lowess, local polynomial regression, or moving regression.
sgFilter() Smooth a signal using the Savitzky-Golay method, also known as least-squares or DISPO (Digital Smoothing Polynomial).
runningAggregate() Visualize stats and how they accumulate per capsule in a condition. See how average, stdDev, min/max change over time.
combineWith() Combine samples from 2 or more signals into 1 without any interpolation effects.
aggregate() The parameters to aggregate() are significantly reworked to make it easier for advanced users to write expressive aggregations of signals and conditions

User Requested Features

Item Trash

Users can reuse signal names if they first throw away unwanted signals via the trash can on the Item Properties associated with the item.

Simplified Capsule Time Selection

All signals in the display range will be overlaid when selected.

Discrete Interpolation in Signal From Condition

Now users can skip a customization step by displaying discrete data as a bar chart with a new interpolation selection in the Signal From Condition Tool.

Recursive searching within Asset Trees

Perform a search at any level of an asset tree and get results that meet that criteria at or below the current level.

Home Page Navigation

Users can now sort content on the home screen by owner in addition to name, last used, and created.

Improved Indexing Efficiency

Optimized data source indexing to reduce metadata sync time.

Select number of Asset Path labels to include in Display Pane

Users can configure how much of the asset path to display in the Trend View labels.

Administrators can view logged in users

Administrators are now be able to sort the user list by who is logged on to see active users.
