No appropriate method, property, or field 'data' for class 'matlabsha​red.scopes​.UnifiedSc​ope'.

I am having trouble with my code on the new 2016 release on my personal computer, whereas my code on an older version at my lab works fine.

The error message is as such: No appropriate method, property, or field 'data' for class 'matlabshared.scopes.UnifiedScope'.

This displays after trying to access the current frame from a movie loaded through the function implay:

fig=implay('movie.mp4');
CurrentFrameNumber = fig.data.Controls.CurrentFrame;

Does anyone have any solutions for this?

Again, this code works on an older release of MATLAB.

Maybe a bit late considering the posted date.

Could it be that the argument is Data with a D capital instead of data with a small d? This has changed for the database toolbox from "data" to "Data"

Unfortunately, no, there is no data or Data field for uiscope objects.

implay has no documented return value. It does, however, currently return a uiscope.

I find in practice that you can use currently

fig.Visual.Image.CData

Unfortunately for any others with this problem, this alteration did not do the trick for me.

I ended up simply doing the necessary analysis with the same code on a different computer and version of MATLAB. Not the ideal solution, but it worked.

In any case, thank you for your answer, Walter.

I re-confirm fig.Visual.Image.CData in R2017b. If it does not work for you then please indicate which MATLAB release you are using.
