The data are not collected from any of the commercial TCSPC devices, so there is no ‘native’ file format other than MATLAB.<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>I have two issues. <o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>The first is speed: export of 128x128 pixel uint16 planes is taking about 60 seconds per 512 planes (using LZW compression). The native MATLAB saving speed for these same data (in matrix, not TIFF format) is 0.2 seconds. I’d really like to export during acquisition, but this doesn’t seem practical with the available tools. Is there an intermediate format that is readily converted to OME-TIFF, which I could write more quickly from MATLAB? Or is there a way of making this more efficient, by writing the planes in a more consolidated way than calling writer.saveBytes for each image plane?<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>The second problem is generating a legal ModuloAlongT annotation (in hopes of trying the FLIMfit package).
