New triggers on previously recorded data?

Hello,

I am wondering if it is possible to run previously recorded data (maybe in simulated mode) and redefine the trigger values.

For example, if we recorded the original data with a trigger of +1.5g, would it be possible to somehow run this data again, but use a trigger of 1.75g?

I am interested in the number of triggers at various acceleration levels, and I was wondering if this can be done using the original data, but modifying the trigger values.

Thank you.

Hi,

I believe you can do something very similar with the file replay functionality. I've attached two zip files. Firstly, you should use the "FileReplayExport" plugin, add it to the addons folder, and you should be able to see a new export option. This will allow you to export the data into a repayable format. Once you have a *.rpl file, you can use the other zip file and follow the tutorial to set up you replay signals. Once the signals are being broadcast, you can set up the triggering conditions however you want.

The only thing I'm not sure about is how Dewesoft will behave if the data isn't stored with the "Always fast options". Perhaps there will be gaps in data, but the more likely scenario is that the last sample will be repeated.

Great! Thank you for your help! I will give it a try and let you know how it goes. Luckily, our data is stored with the "Always fast option."

Hi,

it's no problem. I've also discussed this with my US colleague, who pointed out another alternative for this. From your original email, I understood that you were trying to play back the already recorded data, which is what my example describes. If you're only interested in counting the events when you acc signal crossed over the 1.75 g threshold, then there are easier methods for achieving that directly in analysis.
