Arguments

Arguments Description
datapath string, path to a HDF5 file
dataset string, name of the HDF5 dataset in the file specified in datapath
start int, start of desired slice of the specified dataset
end int, end of desired slice of the specified dataset
normalizer function to be called on data when retrieved
