LI-FLIM stores its data in its own native .fli format. If you choose to save a Sample or Reference file, the phase stack is being stored in this file format including all the acquisition settings and other metadata. The *.fli files can be opened outside LI-FLIM by either the Lambert Instruments off-line version of LI-FLIM or with ImageJ Fiji (Fiji an ImageJ distribution). Optionally, you can choose to store the calculated lifetime images:

  1. Select the Lifetime tab in the image window (it is automatically highlighted once a Reference and Sample have been recorded or loaded)
  2. Select "File" in the upper menubar and choose "Save Active Tab as..."
  3. Here you can select a destination, give it a name and choose a data type. Currently it is possible to export for example *.raw (pure binary data, without the header), *.tiff and to the ICS data format.
