Hello
I have 564 Nifti images, each being 128*128*16*4, as input training data 'imds'. The outputs are 564 continous variables from 0 to 1, which I set as 'imds.Labels'.
I used imagedatastore to combine 'imds' with 'imds.Labels' and then run the regression CNN. But when I run the training, a error suggested that: "the labels of the imagedatastore must be a categorical vector".
Does anyone know how to fix this problem.
Many thanks
Gabriel

Thank you for your response. Actually, I have figured it out, using imds2array().
