We encourage adopting HDF5-Ph-Data format beacuse it is relatively simple, scalable, well documented, space efficient and very fast[Link]. All the FRETBursts example data files are in HDF5-Ph-Data. An additional file-set can be found here[multi-spot paper data files].  Functions All the functions  to load data files the different file formats  are defined in the \verb|loader| module. In particular, to load an HDF5-Ph-Data file use: \verb|d = loader.hdf5(file_name)|  where \verb|file_name| is a string containing the file path. In the previous command, the variable `d` (that (of type `Data`)  is an the fundamental  object of type Data) in FRETBursts that  contains the measurement data and several methods to process it. If you have smFRET In case the  data is available  in another format, you can a format not directly supported it is possible to  manually create a `Data` variable. For example, for non-ALEX smFRET data,you need to create  two arrays of same length: length are needed: the  timestamps and the  acceptor-mask. The timestamps is an int64 numpy array containing the recorded photon timestamps in arbitrary units (usually dictated by the acquisition hardware clock period). The acceptor-mask is a numpy boolean array that is True when the corresponding timestamps comes from the acceptor channel and False when it comes from the donor channel. Once you have these arryas you can manually create a `Data` object with: \verb|d = Data(ph_times_m=[timestamps], A_em=[acceptor_mask], clk_p=10e-9, ALEX=False)|
