DIAdem Idea Exchange

Post an idea

I understand that DIAdem is not a console application, but a GUI-application. Therefore, a python command like

val = input("Enter value: ")

will not work because sys.StdIn and sys.StdOut are not available. However, this isn't well-documented and the error given isn't very helpful.

There are other more complicated outputs that I have seen in the console area of my regular Python IDE (I usually use PyCharm) that fail with very unrecognizable errors in DIAdem Python, usually a string of errors in many scripts that looks very intimidating!

It seems that DIAdem is just grabbing the simple "print" statements from Python scripts, and nothing else works. This would be ok if these errors could be bypassed somehow?

Currently, ONE python engine is started with each instance of DIAdem. This behavior is not well-documented and comes with limitations.

For example, if I have an imported function ".py" script called "MyHelperFunctions.py" and import this into another script, the function is only loaded once. If I make edits to this function, and save the file, the edits will not be available until I close/reopen DIAdem!

I suggest having multiple embedded python engines at the same time. And this would enable DIAdem to always be ready for a python call but still retire a python engine that was bloated.

At the least, having a script command to spin up a new python engine would be very helpful for me!

I would like a feature where you can add extra paths in DIAdem's Python implementation for user-specific Python library directories.

In Visual Studio Code you can edit the settings.json to add paths to:

python.analysis.extraPaths (for importing)
python.autoComplete.extraPaths (for autocompletion)

So stuff imported from "C:\Repositories\Python\MyLibraryOther\__init__.py" is directly visible on import alongside stuff in SitePackages:

I've been able to add further locations to the active DIAdem Python Path via to use programmatically:

import site
site.addsitedir('C:/Repositories/Python/')

With that, I can "use" the script contents from both "Other" and "Site-Packages" items:

But currently I can only "see" items located within the Site-Packages folder:

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

Errors occuring in Diadem user commands result in all running scripts aborting without any clear sign of the reason. The only means to find out is the log file in Diadem Script.

Support says this in a feature, as user commands are supposed to handle events and there should be no (frequent) error messages.

On the other side, user commands are the ideal place to have a user functions library as it is accessible from everywhere including dialogs. With ScriptInclude command such a library has to be included at every script start and possibly several times as dialogs have a separate script environment.

Therefore I would welcome an option to turn on error messages / beep when there is an error in user commands.

The current behaviour of silent abortion of any script is quite confusing, especially for people that are only applying scripts for evaluation.

We are very happy about the support of Python as additional language in DIAdem script.

It would be a really nice feature if the DIAdem Python module would also be available in Python scripts that are running not within DIAdem script but on a machine with valid DIAdem license.
This would allow to create Python applications that use DIAdem commands but do not require the user to explicitly open DIAdem and load a Python script and thus improve usability.
Another use case would be an improved communication between Matlab and DIAdem by calling Python code including DIAdem commands from Matlab as executing Python code from Matlab is possible.

I was using an “assignment” channel as the “ChnEventTrueChn” for “ChnEventCreateFilteredTrueChn” and was really hoping the result channel would also be an assignment channel, but no, it’s not.

My original assignment channel is matched up nicely with some text values, so it would be really helpful to have those values “carry” if I execute a function or calculation on the numeric channel.

FYI, Brad Turpin provided a workaround until this is implemented that works just fine for me:

Clone your assignment channel and use the clone for the ResultChannel channel in the “ChnEventCreateFilteredTrueChn” function.

Set OldGroup = Data.Root.ChannelGroups(1)

Set NewGroup = Data.Root.ChannelGroups(2)

Set OldAssignChannel = OldGroup.Channels(1)

Set NewAssignChannel = NewGroup.Channels.AddChannel(OldAssignChannel)

Call ChnEventCreateFilteredTrueChn(NewAssignChannel, ChnEventList, OldAssignChannel, ChnEventFalseValue)

Using Calculate for basic mathematical functions is like taking a sledgehammer to crack a nut. Cause Calculate takes ages compared to e.g. ChnAdd, ChnMul, ChnDiv etc. But on the other hand it lets you script formulas in an easy-to-read format.

The idea is to have a pre-processor analyzer for scripts that identifies Calculate commands and checks if these commands could be translated into a series of these basic mathematical functions. If yes, then the script engine should be able to do so in the background in order to speed up the calculation.

I would like a tool that would help identify noise spikes in my data, so that they may be set to NO VALUE or carefully interpolated. In the attached example, I have two torque spikes in my data that are significantly higher than the mean. If I were only looking at one file, I would simply "Set Flags" in VIEW, then "Flags: Remove Data Points". However, I am reviewing dozens of files with several channels of interest.

Peak data points are the most damaging to the components under test, so it is important that we keep the real events and reject the noise.

Concerns with other peak / spike removal options:

Manual Set Flags -> Flags: Remove Data Points; time required
ANALYSIS -> Event Search -> Event = Window -> Upper Limit: In other data files, I have real events with values higher than the noise in this data file.
ANALYSIS -> Digital Filters or Smoothing: This will change all of the data - it will likely narrow the peak-to-peak of my other data and interpolate my noise spikes, adding damage that is not actually real. I only want to remove a few data points in the channel data.

nCode Glyphworks has a nice Spike Detection Tool that uses 6 available algorithms to detect spikes. Once it identifies them, it allows the user to see them, prior to performing any actions - this is important, because it allows the user to identify if they are real or noise, prior to taking action.

Currently you can only search for one channel at the same time with the advanced search as shown in the first graphic. if you select two channels at once, no search results will be found.

It would be very helpful if you could search for several channels with different characteristics at once.

for example, one could look for measurements that contain a first channel with a particular property and at the same time contain a second channel with a different property. It would also be helpful if the different properties of the search were linked by setting the brackets.

here's an example

Diadem Bsp2.PNG

such a function would greatly facilitate the evaluation of large data volumes.

best regards
