Asammdf extracting more metadata

Question

Hi I am using asammdf library for handling MF4 files. When I open the file using asammdf GUI , in Info tab I can see information . I am trying to extract the same info by calling .info() function on the same file as below.

data = MDF(r"C:\Users\vaasu\Desktop\data\Recorder_2020-06-05_10-22_0120.MF4")  

print(data.info())

But this is only giving channel group information. But I need "program identification" and "Measurement comment" as well. How can I read that using asammdf API?

You can see what attributes are accessed starting with this line https://github.com/danielhrisca/asammdf/blob/af1b9b1a213fbfc33a77d41c9d7aca2257e0c320/asammdf/gui/widgets/file.py#L376

Thank you. That helped. And is it possible to load metadata of a file without creating an object of MDF? Because `MDF()` takes more time. – srinivast6 Jul 22 '20 at 04:52
Do you need the channel group information or just the measurement header information? – danielhrisca Jul 22 '20 at 12:48
List of channel group and signal names in them. Thank you – srinivast6 Jul 23 '20 at 05:25
I've updated the info function in the development branch. For a complete overview of the channels you could have a look at the mdf.channels_db dict – danielhrisca Aug 10 '20 at 05:20
