Removing Repeatedly Occurring Values in a Channel

[warburtonj]

Is there a way of only deleting values in a channel when for example there are more than 10 values in a sequence the same.

I tried using 

ChnDeleteDuplicateValues(chnData, , "absolute", 10, false,"FirstNonNoValue")

but I can only adjust the tolerance that the values differ by.

Hey Warburtonj,

Is the talk about DIAdem scripting here?

[warburtonj]

Yes I need to be able to implement this in a Diadem script.  Only replace values in a channel with NOVALUE when there are say 10 values in sequence that are the same.

Hello warburtoni,

I think you can use the Channel Event Functions for this. The first step is to find all values where the difference is zero. In the second step all results with more than 10 hits are filtered. The third step is to create a result channel.

ChnEventList1 = ChnEventDetectionDifference("", "[1]/Signal", 0, "absolute-exact")
'Call ChnEventCreateFilteredFalseChn("/EventStatus1", ChnEventList1, "[1]/Signal", NOVALUE) ' for test only

ChnEventList2 = ChnEventFilter(ChnEventList1, "Peaks", 10 , "Index")
Call ChnEventCreateFilteredFalseChn("/EventStatus2", ChnEventList2, "[1]/Signal", NOVALUE)

Greetings
