Resample function that returns numeric channels

Status: New Submitted by Active Participant on 10-13-2021 06:24 AM 1 Comment

Many functions in DIAdem seem to be biased towards waveform channels, ignoring the classical ways of working with standalone numeric channels.

 

The ChnResampleFreqBased function returns waveforms when I think it should have the option to return standard numeric channels. My workaround is not to use it at all and to use the channel generation and linear mapping functions instead.

 

This obviates the need to reformat channels (wherein you also get a new X channel that you might not have wanted) and is less code. But why have to use two functions to get the same output that could have come from the one resampling function were it to have the option to provide numeric channels?

 

Regards.

Improved Help entry and script recording for "Converting Numeric Channels into XY-Channels"

Status: New Submitted by Member on 09-13-2021 08:30 PM Comment

Today I was trying to find the SCRIPT command for "Converting Numeric Channels into XY-Channels" and could not easily find it or record a script to find it. So two requests here: (1) when recording a script, output the script or have a message that says 'sorry!' and (2) update the help with the correct script functions, similar to the other channel conversion functions.

 

I tried to record a script, executing the ANALYSIS function "Channel Functions -> Channels <-> XY Channels", but nothing showed up in the recorded script.  

 

Looking up the help reference for "Channels <-> XY-Channels" only shows how to display the dialog, Call SUDDlgShow("Main", ResourceDrv & "AnaChnToXYChn")

All of the other "channel conversion" help documents show how to do this in SCRIPT, for example, "Numeric Channels <-> Complex Channels" shows "

ChnConvertNumericToComplex", similar for the Numeric to Time, Waveform, etc. My proposal is below:

 

Script Call:

Call SUDDlgShow("Main", ResourceDrv & "AnaChnToXYChn")

 

Set Group = Data.Root.ChannelGroups(1)

Set XChannel = Group.Channels(1)

Set YChannel = Group.Channels(2)

Set YChannel.XRelation = XChannel
