Dynamic Channels

[Julia Dawkins]

I would like to know if there is a way to create a dynamic channel in DIAdem. I see the variable "ChnType" will tell if a channel is fixed or dynamic, but can I set a channel to be dynamic? I also need to know what DIAdem means by "dynamic" channel.

What I understand dynamic to mean is as follows: for example, ChnA = ChnB + ChnC. If ChnB or ChnC change values after calculating ChnA, ChnA will not update its value if it is a fixed channel, but will if it is dynamic. Is this type of dynamic channel availble in DIAdem?

Thank you!

Hi Julia,

In DIAdem static channels are those which are declared in the Menu -> Settings->Memory management->Data area. That means static channels specify a number of channels which are created at launch time of DIAdem and which are always available.
With DIAdem 8 we expand the data management in DIAdem so that you are able to create a channel only if you need one. To prepare a channel in this manner you can use the command ChnAlloc. The mathematical functions create the result channels themselves. The procedure to create a dynamical channel is to look first whether a static channel is already available and only if not create a new channel in the memory (this is done automatically from DIAdem).
What you are looking for is a mathematical channel. That means a channel contains mathematical function which describes how to calculate a channel (e.g. ChnA = ChnB + ChnC * 17). But this kind of channel DIAdem doesn’t support (at the moment). To have something similar you can create a script. A script has more possibilities than a mathematical channel. You can include the whole process, starting with loading files, analysing the data, creating reports and ending with printing the results or creating PDF’s of the results etc.
I hope this will help you.

Yes, thank you.
