Split multiple channels brake test into smaller parts by trigger.

[JohnnyHick]

Hello fellow DIAdem users.

I have a question that i would like to have some help with if you feel like you have the time.

I want to start of by saying that my programming skills are rather low.

Ill try to explain my problem as detailed as possible

The thing i want to do is to program a script/program(dialog interface) that takes some channels as input (from like a combobox) and a trigger.

When i run this script/program i want it to "CUT" the parts where the trigger is 1 (see example.jpg below) and save it to a new channel and a group.

So after the programm have executed i would like it to look like this after the channels used by the program in dataportal;

Test1       (group1)

--Trigger S1

--pressure FA S1

--pressure RA S1

--Velocity S1

--Temp disc S1

--pressure FA S1_1

--pressure RA S1_1

--Velocity S1_1

--Temp disc S1_1

Test2            (group2)

--Trigger S2

--pressure FA S2

--pressure RA S2

--Velocity S2

--Temp disc S2

--pressure FA S2_1

--pressure RA S2_1

--Velocity S2_1

--Temp disc S2_1

.

.

.

Hope you understand what im aiming for.

I have been inspecting the channels manually before and have not been in need of automating. But now when there are 100+ triggercycles its to much to handle.

Would be so much easyer to just check out for example. group 52 and calculate mean and important formulas for just that test. 

A programm like this would help out a lot.

I can add that i have went throu all of the 115 pages of POSTs here trying to find something like the problem i have, But without succsess.

I have tryed using a loop to find out at what row the trigger changes, but i just cant get the hang of it.

Im sorry for the wall of text. Just want to be as detailed as possible.

The channels are Time on the X-Axle, and Y-Axle differ from Psi to Celcius. 

Anyone out there who have a simmilar program that they can share, Or someone who could give me some pointers where to start?

Thanks in advance

Hi,

I think I have something which is close to what you are looking for. I've been through the process of automatically "cutting" sections via a script. My scripts saves each section to a new dataset onto your hard drive as opposed to creating the groups in the data portal though. Basically you supply the script with criteria such as :

1) ChannelID

2) Rising Trigger threshold.

3) Falling trigger threshold.

4) Rising trigger margin

5) Falling trigger margin

Could you post an original data set and say the first 3 sections you have cut by hand so that I can have something to work with?

Johnny,

I would use a loop that uses the Call GroupCreate("Test"&i) to create a group.  Then the "find" function to find when a channel (trigger) exceeds a value to find the cut points, you can also input a start point so as not to re-copy data by setting one of the internal globals to the last point found (L1, L2,L3...).  Then I would use the dataareacopy function to copy that data to another data channel in the new group. then increment the i counter.

L1 = FIND("CH('Trigger')>=2.5",L2)

L2 = FIND("CH('Trigger')<=2.5",L1)

Call DataBlCopy(ChnNoStr, ChnRow(L1), ValNo(L2-L1), ChnNoStr1, TargetLine(1)) ---Parens for example

Then loop.
