While FRETBursts can load data files from a variety of file formats,  the authors encourage adopting \href{http://photon-hdf5.readthedocs.org/}{Photon-HDF5},  a format specifically designed for freely-diffusing smFRET and other timestamp-based data. experiments.  Photon-HDF5 is a self-documented and efficient format  that which  allows saving boththe  raw per-photon data andthe  measurement-specific meta-data (setup and sample information, authors, provenance etc...).  Photon-HDF5 assures long-term accessibility of the data and aims to ease data sharing   among different software and research groups.  All the FRETBursts exemplary exemple  data files are saved in Photon-HDF5 and can be opened with standard viewers such as \href{http://www.hdfgroup.org/products/java/hdfview/}{HDFView}.   Additional data files can be found here[multi-spot paper data files].

(see section~\ref{sec:data_intro}).  The same command can load data from a variety of measurement types stored   in a Photon-HDF5 file. Specifically, For instance,  data employing generated using  different excitation schemes (CW vs pulsed, single-laser vs 2 alternating lasers) or with any number of excitation spots  is automatically recognized.  Other file formats that which  FRETBursts can load include μs-ALEX data stored in SM sm  format (a binary format saved by a common LabVIEW program formerly  used in μs-ALEX-smFRET setups), our lab),  ns-ALEX data stored in SPC format (a binary format used by TCSPC Becker \& Hickl cards).  More information on loading those these file  formats and on manually loading other arbitrary formats can be found in the   \href{http://fretbursts.readthedocs.org/en/latest/loader.html}{\texttt{loader} module documentation}.

\subsection{Alternation parameters}  \label{sec:alternation}  For µs-ALEX and ns-ALEX data data,  it is necessary to identify thedifferent  alternation periods for donor and acceptor excitation.  The functions
