I've been trying to train a network for 3D segmentation.

The input data is 3-dimensional array(or image), its response is 4-dimensional array, loaded using imageDatastore. I want to start training of network, but I faced error messages, which is below. This error raised because dimension of the input and its reponse doesn't matched(input:3d vs response:4d).

Is there any way to give combinedDatastore which consists of different dimensions of input and response to trainNetwork function?

Error using trainNetwork

Error during read from datastore.

Error in resunet_test (line 72)

[net_, info] = trainNetwork(combine(trntf_input, trntf_label), net, opt);

Caused by:

Error using horzcat

Dimensions of arrays being concatenated are not consistent.

Error in matlab.io.datastore.CombinedDatastore/read (line 146)

data = horzcat(data{:});
