Set property for capsules

[JWu]

I have only 6 capsules under a condition.  Without importing CSV file, could I set a property for capsules by giving different numbers? Thanks!

I am sure that there are probably a few ways to do this but here is a solution I came up with 

$conditionToSamples = $condition.aggregate(count(),$condition,durationkey())

$countingRange = condition(capsule('2020-01-01T00:00Z', '2023-01-01T00:00Z'))

$countSignal = $ConditionToSamples.runningsum($countingRange)

$condition.setProperty('Capsule Count',$countSignal,average())

Step by Step Outline 

1. $conditiontoSamples - Take your input condition and turn it into a signal with a value of 1 whenever the condition exists 
2. $countingRange - the range we are going to count these capsules over. In this example beginning of 2020 to beginning of 2023
3. $countSignal - Create a signal that counts up those values for each condition starting at the start date 
4. Set the value of the $countSignal as a property on your original condition

Depending on whether you want the numbers to be 1-6 or just a unique identifier, another common approach is to use the timestamp of the start of the capsules. In this case, you could do something like:

$condition.setproperty('ID', $condition.tosignal('start').tostring(), startvalue())

Thanks, Shamus and Joe!  How about any numbers which are not coming from signals, let's say 23, 14.5, -3, 0, 65, 4, could we set those numbers as properties of the capsules?

Hi JWu,

The easiest way would be to use the Manual Signal tool (https://support.seeq.com/space/KB/1795391628/Manual+Signal) to create a new signal where the values line up with when the capsules are present and then setting that as a property on the capsules.

Thanks, Joe!  This is indeed what I want.
