Description

Hi, I'm trying to open a mdf4 file created by Acontis Real-time Data Acquisition (DAQ) Library. Here the link of the website: [https://www.acontis.com/en/real-time-data-acquisition.html]

The library generated a file (ecmaster_daq.zip)

I tried to open it using asammdf GUI but there is anything on the channels tab image Any idea why I couldn't see anything? Thanks

It means that the file does not contain signals

Is there a way to open the mf4 file and look for the signals? The Acontis library provide only the API functions to configure and write the files so I couldn't look into that

danielhrisca commented 4 weeks ago

There are no signals in the file, but if you want to double check you can download Vector MDFValidator and open the file with it

I used Vector MDF Validator and this is the result: image

No data groups = no signals
