 -mask_file mask_file_tiff (takes an input image uint16_t, assumes all zero regions should be ignored by the APR, useful for pre-processing of isolating desired content, or using another channel as a mask)
 -rel_error rel_error_value (Reasonable ranges are from .08-.15), Default: 0.1
 -normalize_input (flag that will rescale the input from the input data range to 80% of the output data type range, useful for float scaled datasets)
+-store_delta (stores the delta between an APR reconstruction and the original image as an additional hdf5 file)
+-compress_level (the IO uses BLOSC for lossless compression of the APR, this can be set from 1-9, where higher increases the compression level. Note, this can come at a significant time increase.)
