I have already tried yesterday to change the number in a .sp file that were near to the txt GMB file but without success.
The only solution is to wait the conversion utility
In the CXF, make sure that the light is normalized at 560nm or 560nm = 100.00
I don't understood this words. In the txt file there is no reference at all.

Marco,So getting back to your orginal question, I don't know of any utility or procedure that will give you what you want but you can do the conversion manually. In the CXF, make sure that the light is normalized at 560nm or 560nm = 100.00. If that's the case, if I were you, not knowing more aboutany Argyll's utility that Graeme may have already written to do thisconversion, I would start from, say, D50_0.0.sp and change the values youneed to change to work with your particular custom light source. I don't think this is more difficult than that?I copy and paste from the documentation: "Spectral illuminant description. This is an ASCII text, CGATS, Argyll specific format, used to hold a spectral description of an illuminant. Typically it is used to record a custom illuminant, for use in computing Fluorescent Whitening Agent compensation for reflective samples, as well as computing CIE tristimulus values from spectral samples." I want find the Lab value starting from both spectral data of patches and of light.
