Bug: Compability with jpk-force-map

[Kutzti]

There is currently some compability problem with .jpk-force-map. Neither .load_data() nor load_group() nor QMap() can handle force maps.
Each of the upper methods lead to an empty group.

It could be that the file format changed. Do you have an example file we can use for testing?

[Kutzti]

Of course! Thank you for your time!
Example_data.zip
Sorry for the zip, apparently GitHub does not like .jpk-force-map files...

[Kutzti]

Apparently it doesn't like all of the jpk-Files, I also tested jpk-force and it does not work

By any chance you haven't had time to take a look? The software from jpk itself is...well... improvable.

Hi, unfortunately I did not have time yet to look into it, sorry.

@Kutzti It looks like there are three segments per curve in the file. What are those? For force-indentation measurements, nanite expects two segments per curve (approach and retract).

[Kutzti]

These segments are pauses. Interesting, I was not aware of the fact that only 2 segments were expected.
This could also be the problem if we try to load data with afm-formats from the .jpk-force file when using ocillations.
Thank you!

OK, what is the reasons for these pauses? And how are you implementing them (constant height or constant force). AFAIK, there should not be any pauses, because then you would be mixing force-indentation with creep-compliance or stress-relaxation.
