Hello, I am new to argyll and color managment in general so I apologize for this basic usage question. When I run scanin I get a .ti3 file with no data. The command I use is scanin -v -dipn cropped.tif "ColorCheckerSG.cht" "Digital ColorChecker SG.cie" The diagnostic image shows perfect matching with the outlines and the image, but I get a series of warning messages. Warning: Couldn't match field '01' ... ... Warning: Couldn't match field '140' The .ti3 file that get created only has this information CTI3 DESCRIPTOR "Argyll Calibration Target chart information 3" ORIGINATOR "Argyll target" CREATED "Mon Jun 09 06:34:49 2008" KEYWORD "DEVICE_CLASS" DEVICE_CLASS "INPUT" KEYWORD "COLOR_REP" COLOR_REP "XYZ_RGB" KEYWORD "STDEV_R" KEYWORD "STDEV_G" NUMBER_OF_FIELDS 10 BEGIN_DATA_FORMAT SAMPLE_ID XYZ_X XYZ_Y XYZ_Z RGB_R RGB_G RGB_B STDEV_R STDEV_G STDEV_B END_DATA_FORMAT NUMBER_OF_SETS 0 BEGIN_DATA END_DATA I am using the V0.70 Beta 8 release.
