54 SPCM Software
The ‘Convert FIFO’ routine allows you to convert .spc files into different destination file
types. The destination file type is specified in the ‘File Format’ field in the lower part of the
Convert panel. The most frequently used conversion is into .sdt files of the TCSPC FIFO
mode, see Fig. 87.

Selection of the functions to be calculated and calculation parameters.
The functions to be calculated are defined in the ‘Select & configure histograms’ field. A click
into this field opens the panel shown in Fig. 87, right. It is the same panel used to configure
the online display of the FIFO mode, see ‘Configuring the Runtime Display’, page 45. You
can specify the calculation of decay curves, FCS functions, photon counting histograms
(FIDA), photon counting lifetime histograms (FILDA), and FCS traces.
A FIFO measurement may have been run over a long acquisition time and contain data from
several routing channels (detectors). Therefore, parameters are provided to control the struc-
ture of the calculated data. With ‘Time Interval’ and ‘Starting from Time’ a time interval
within the ‘Overall measurement time’ of the FIFO measurement can be selected. Moreover,
if the .spc data were recorded in several detector channels the full routing information may be
used, only a specified range of channels may be converted, or the routing information may be
ignored altogether, i.e. all detector channels merged.
