Dear Klaus, Gerarhd und Graeme,
My first results with logo2cgats are not proving a success. I'm getting
'segmentation fault' error. The output log is as follows:
> ~/desktop/argyll_osx10/bin : logo2cgats -2 -V -l400% mesures_eci.txt eci
> Single source file, assumed dev/cie/spectral
> Assumed to be a CMYK device
> Read device values
> We've got a combined device + cie/spectral file
> Read CIE values
> Segmentation fault
Here's an excerpt the measurement file:

I have to confess that the original measurement data did not come from
MeasureTool but from PrintOpen. I tried feeding the PrintOpen file directly
into logo2cgats but gave up when I got the following error message:
> Input file 'mesures4M.txt' doesn't contain exactly one tablelogo2cgats: Error
> - Field SampleName (SAMPLE_NAME) from CMYK/RGB file 'mesures4M.txt' is wrong

So I opened the PO5 into MeasureTool and resaved as a GMB file.
Obviously, my eci.ti3 file was empty :(
I'll experiment some more...
