1. ## Finding Periods of Overlapping Events

FAQ: How do I identify time periods where I have overlapping capsules within the same condition? I may want to keep only the capsules (time periods) where capsules overlap. I may also want to keep the times where a certain number (2, 3, or more) of capsules overlap. In this example, we will find time periods where there are at least 2 overlapping capsules which make up the Event Condition. In the screenshot below, you can see there are 3 separate time periods where the Event condition capsules overlap: Step 1: Merge any overlapping capsules together using the merge() function
2. ## Create a condition for a variable portion of another condition

FAQ: I have a condition for events of variable duration. I would like to create a new condition that comprises the first third of the time (or 4th, or 10th) of the original condition. Solution: A stepwise approach can be taken to achieve this functionality. 1. Begin with your condition loaded in the display pane. 2. Create a new Signal using Signal from Condition that calculates the total duration of each of your event capsules, interpolated as a step signal. 3. Create a new signal that is your total event duration multiplied by the proportion of t
3. ## A Guide to Working with Capsule Properties

Capsules can have properties or information attached to the event. By default, all capsules contain information on time context such as the capsule’s start time, end time, and duration. However, one can assign additional capsule properties based on other signals’ values during the capsules. This guide will walk through some common formulas that can be used to assign capsule properties and work with those properties. Note: The formula syntax used in the following examples will all be based on the formula language for Seeq version 49. If you have questions about errors you may be receiving
4. ## Adding and Using Capsule Properties

Background: A property can be added to capsules for further filtering and aggregation through Seeq tools, including Histogram. All properties on a condition are stored as string values. This post examines how to add a property to a condition and then how those properties may be used. Adding Properties to a Condition Capsule properties may be used to store important information such as, Product Codes, Batch IDs, and Recipes. There are three functions in Seeq Formula which can add properties to the capsules in a condition: toCondition() - Dedicated function to transform a
5. ## Creating a Signal for a Running Count of Capsules

FAQ: I've created a condition for a particular event of interest and now I would like to create a signal that is the running count of these events in a given time period. This analysis is common in equipment fatigue use cases when equipment degrades slowly based on a number of cycles (thermal, pressure, tension, etc) that it has undergone during it's life or since a last component replacement. Solution: We can convert each of these capsules into a signal comprised of a single sample (with value of 1) per capsule, then take a running sum of this new signal over the cu
6. ## GetStart() function use

Hello everyone, I want to get the first value of signal within capsule. When I use getStart it returns No variant of function 'toscalars' consumes the parameters (Signal, Condition) at 'toscalars' Same with following function: \$signal.toscalars(\$capsule).first() When I created capsule inside formula everything works fine: \$signal.toscalars(capsule(now() - 6y, now())).first() Thanks
7. ## Counting capsules

Is there a way to count capsules? For example, I have created a value search in my data to show me all values above 70%. This forms capsules at the top of my timeframe. However I would like to now count how many capsules are in the selected timeframe (ie from November to January). I have tried using the "count" formula however it is showing a trend with a value every time the value search shows above 70%. I am looking for something that will tell me there were 87 capsules in the timeframe. And if I change the timeframe, then this value would change. I hope this makes sense. Thank y
8. ## Selecting Capsules within a Condition

In some cases you may want to do a calculation (such as an average) for a specific capsule within a condition. In Seeq Formula, the toGroup() function can be used to get a group of capsules from a condition (over a user-specified time period). The pick() function can then be used to select a specific capsule from the group. The Formula example below illustrates calculating an average temperature for a specific capsule in a high temperature condition. // Calculate the average temperature during a user selected capsule of a high temperature // condition. (The high temperature condition (\$Hi
9. ## Daily Capsules Don't Start at Midnight

I have created a daily condition in Seeq using the Periodic Condition tool. Why don't the capsules start at midnight? For example, in the screenshot below the "Daily" capsules start at 11:00PM (see the Capsules pane) instead of midnight (12:00AM). This results when the user interface (UI) time zone does not match that of the Seeq Server. In this example the Seeq Server time zone is US/Eastern but the UI time zone is US/Central. To make the UI time zone match, the user can click on the UI time zone link (noted by the red box in the screenshot: trend display, x-axis, right of timestamp):
10. ## Count Events in Boolean Signal

I have a Boolean signal and would like to count the number of events over a specified time period. How can this be accomplished in Seeq? Thanks, Sam
11. ## Count the Number of Times in Each Stage

Hi- I have a process that goes through several different stages during its operation, e.g. 'Stage 1', 'Stage 2', 'Off' etc. I'd like to determine a count or frequency that my process is in each of these stages. What is the best way to do this?
