I have tried the replacement in the .sp file, the module spec2cie makes the conversion, but regarding the found values ...
I have tried two conversions, a D50 and a custom illuminant (10000K). I have opened the ti3 resulting files and look at the first sample (first patch of the colorchecker) after BEGIN DATA 


1. the RGB value are the same in the two files (in what colorspace?)
2. the spectral values are the same (they are the spectral data samples of the CC) 3. The Lab value is very different, the D50 value are ok, the 10000K value are wrong (first patch D50: 39.773 12.878 13.695 10000K: 38.689 7.1901 -7.0360 this last is a purple-gray?) 

This is not normal. Have you experience?

Marco

How many fields are to change? All after "BEGIN_DATA_FORMAT" is

enough?

Si.
