issue about how to make training data

I fine out that  binfile's shape is (4,32,128,171), including seg's shape(3,32,128,171) and label's shape(1,32,128,171). When i making the training data,because it is one-hot label,the label's shape will be (22,32,128,171),and the final binfile's shape is (25,32,128,171).Is it right? And can you share your training lst file? I am confusing in making the train set. 
Thank you!
