Using pixelLabelDatastore with data obteined of lidarLabeler

I have lebeled data from lidarLabeler and I want use the function pixelLabelDatastore with this, to get data to train a CNN. I am following the instructions for its use:

pxds = pixelLabelDatastore(gTruth)

But Matlab shows me the following error:

Error using pixelLabelDatastore (line 210)
    Not enough input arguments.

I don't nknow what is the problem because the file that lidarLabeler create, is in gTruth format.

Hi Jesus Garcia,

The error you're encountering is due to a mismatch between the type of ground truth object you are passing to the “pixelLabelDatastore” function and what it expects. The “pixelLabelDatastore” requires input in the form of a “groundTruth” object typically exported from the “Image Labeler” or “Video Labeler” apps.

In your case, it seems that the “gTruth” object was generated using the Lidar Labeler app, which creates a “groundTruthLidar” object.

For more information you can refer to the below documentation link on “groundTruth”:
