ZEN Core acquisition script crashes

[Andrei Poliakov]

Seeking advice on an error message occurring during operation of an OAD acquisition script reported by a client. The script automates taking multiple images to cover a chosen sample area, so nothing terribly complex: camera frame size adjustment, stage movement, acquisition, image saving. Known to work well with multiple installations, but one client reports an intermittent error message:

Scripting Error Error in the executed macro. The ZEN Service reported the following error: An error occurred when the parameters have been applied synchronously. This maybe caused, for example, by a timeout. The ZEN Service reported the following error: An error occurred when the parameters have been applied synchronously. This maybe caused, for example, by a timeout.

(Yes, most of the text is duplicated.) No details, e.g. where exactly in the code the error occurs, available at this stage. The error message is not immediately informative either.

Can you advise what may be causing this kind of error and possible remedies?

Implement proper debugging and logging mechanisms within the script. Add print statements or logging functions at different stages of the script to identify where the crash occurs. This can help pinpoint the cause of the crash and provide more specific information for troubleshooting. Ensure that all required dependencies, libraries, or modules are installed correctly and up-to-date. Check for any compatibility issues between the script and the versions of the dependencies you are using. Pay attention to resource usage within the script. If the script consumes excessive memory, CPU, or other resources, it may lead to crashes. Optimize resource management by releasing unused resources and handling large datasets efficiently.

I'm currently working on improving my coding skills, and these debugging and https://lesturf.com/what-to-do-when-thi ... ing-out-2/ logging tips are really helpful. Thanks for sharing!

Make sure the script has the right debugging and logging features. To find out where the script crashes, add print statements or logging routines at different stages. More precise information for debugging and determining the crash's cause can be obtained from this. Verify the proper and current installation of any libraries, modules, or dependencies that may be needed.

While I am kind of grateful for general debugging advice received through a couple of posts, my specific question was, sadly, never answered. Please note that I was talking about an intermittent error occurring at a remote client's site. My ability to perform proper debugging in such situation would have been extremely limited and I hoped to at least narrow down the list of possible culprits by getting the error message interpreted for me.

Anyway, based on my experience with multiple occurrences of this or similar errors in different environments, I can also share a bit of advice. Upon acquiring an image Zen seems to save it inside some temporary directory under a name that gets auto-incremented on every save; the temp image is meant to be auto-erased once, for example, saved under another name. Apparently on some occasions different Zen threads get the same number from the increment counter (or similar) and try to access (write or erase) the same image file, resulting in at least one of them failing. On other occasions (script or Zen crashes?) temp files may be left forever in the temp directory flagged as open, resulting in script errors once the auto-increment reaches their number.

So, if experiencing unexpected errors during acquisition, one can consider the following: (1) locate the temp directory (can be different depending on version, just search for ".czi"), see if there are any files left when nothing is open in Zen, and try removing them manually, and (2) introduce timeouts in the code to avoid possible conflicts between threads, 1 sec per acquisition seems to do the job and is not critical in terms of execution time.

Also, just in case: this behaviour is not Zen Core specific and can occur in Blue as well.

EXPLORE PUBLIC ARTS, PLACES TO EAT AND GO BOWLING IN DUBLIN OHIO

Stop at Fado Pub & Kitchen for a true delight of Ireland. Back story: We recently honeymooned in Ireland, and when we heard the owner was actually from Dublin, we knew we had to add this restaurant to our places to eat.
The atmosphere here is laid back, and the open-concept decor gives a truly authentic Irish pub. Go ahead and have a Guinness to kick things off, we promise no one is judging!! My wife went for small plates and ordered roasted beet hummus, fried goat cheese, and chili garlic shrimp while I stuck to the brick-roasted half chicken for dinner. Every dish brought back memories of our time in Dublin. We loved connecting with the owner, sharing stories, and learning about his journey. If you’re into authentic experiences, Fado Pub & Kitchen is no doubt a must for meal.

For intermittent error messages in a script that's otherwise known to work well, there are a few common troubleshooting steps you can take:

Check Logs: Review the logs or error messages reported by the client. This can often provide clues about the nature of the issue.

Error Details: Look for specific details in the error message, such as error codes or descriptions, to narrow down the problem.

Environment: Ensure that the client's environment matches the requirements of the script (e.g., camera compatibility, stage movement accuracy).

Permissions: Verify that the script has the necessary permissions to access and modify files or settings required for operation.

Update Script: If the script has been updated recently, consider rolling back to a previous version to see if the issue persists.

Client-Specific Factors: Investigate if there are any unique factors in the client's setup that could be causing the issue (e.g., hardware differences, software conflicts).

Test Environment: Try to replicate the issue in a controlled environment to isolate the cause and test potential solutions.

User Interaction: If the script relies on user input or interaction, ensure that the user is following the correct steps and providing valid inputs.

By following these steps, you can often identify and resolve the cause of intermittent errors in a script.

If you are experiencing crashes with a ZEN Core acquisition script, it could be due to a variety of issues ranging from software conflicts, bugs within the script, or even hardware communication problems. Here are some general troubleshooting steps that could help resolve the issue:

Update ZEN Software: Make sure you are running the latest version of the ZEISS ZEN software, as updates often include bug fixes and improvements that could resolve your issue.

Check the Script for Errors: Review the script code for any syntax or logical errors. Sometimes, crashes can occur due to simple mistakes in the code.

Resource Conflicts: The crash might be related to resource conflicts, such as multiple threads trying to access the same image, as mentioned in a ZEISS Microscopy Developer Forum thread. Ensure that your script handles concurrent access appropriately.

Contact ZEISS Support: If you are unable to resolve the issue, consider reaching out to ZEISS technical support for assistance. They may be able to provide specific advice or updates that can fix the problem.

Community Forums: Look for solutions or ask for help on forums such as the ZEISS Microscopy Community. Other users may have encountered similar issues and could have solutions.

Script Debugging: Use debugging tools or logs to trace where the script is crashing. This can provide insights into what part of the script is causing the issue.

Check Compatibility: Ensure that your script is compatible with the version of ZEN Core you are using. Incompatibilities can often lead to crashes.

Reduce Complexity: If the script is complex, try simplifying it or breaking it down into smaller parts to isolate the cause of the crash.

Remember to always back up your existing data and scripts before making any changes, and proceed with caution when troubleshooting software issues. If you are not confident in resolving the issue yourself, professional support is the best course of action. https://paybyplatema.life/
