Hello, I downloaded the 64 bit version 1.5.1 and created an ti3 file for my scanner. But the conversion to ICM with colprof failed with an error: gregor@valun:~/work/scanner$ scanin epson2400_it0872.tiff Argyll_V1.5.1/ref/it8.cht R120505.txt Writing output values to file 'epson2400_it0872.ti3' gregor@valun:~/work/scanner$ Argyll_V1.5.1/bin/colprof -v epson2400_it0872 Argyll_V1.5.1/bin/colprof: Error - CGATS file read error : Error in file 'epson2400_it0872.ti3': Field 'STDEV_B' has unexpected type, should be 'real', is 'non-quoted char string' Is there a bug or an error on my side (I am new to the software and calibration) ? You can find the ti3 file here: http://gregor-horvath.com/epson2400_it0872.ti3 Thank you. -- Greg
