Well, it can be a bit tricky to convert the comma delimited CGATs files to text delimited. And there is usually a lot of extraneous header information that might mess things up. You could try stripping out the unnecessary header information and just use something minimal like this:
"TARGET_TYPE ""ANSI IT8.7/3"
NUMBER_OF_FIELDS 11
BEGIN_DATA_FORMAT
SAMPLE_ID CMYK_C CMYK_M CMYK_Y CMYK_K XYZ_X XYZ_Y XYZ_Z LAB_L LAB_A LAB_B
END_DATA_FORMAT
NUMBER_OF_SETS 928
BEGIN_DATA
1 100 0 0 0 18.71 24.5 35.94 56.58 -23.4 -26.45
2 0 100 0 0 30.38 20.76 17.61 52.69 44.14 -1.09
3 0 0 100 0 47.52 50.81 11.9 76.57 -4.05 54.72
4 100 100 0 0 11.52 11.1 17.18 39.74 6.02 -22.44
Then again, you say it only locks up when you load in a lot of files. So if it’s working okay for a few, then it should work okay for more. How many files did you load in? I have given it about 13 without any problems. Maybe you had a bum sample reading in there?
