[SOLVED]Read 'Transaction' file problem

wujiang

Hello,

I want read a file like this:

a b c d e f g h i j k l m n o p q r s t u v w x y z aa bb cc dd
30 31 32
33 34 35
36 37 38 39 40 41 42 43 44 45 46
38 39 47 48
38 39 48 49 50 51 52 53 54 55 56 57 58
32 41 59 60 61 62
3 39 48
63 64 65 66 67 68
32 69
48 70 71 72

I use the 'Read CSV' operator, and split by the ' '

so I got a dataset like

30 31 32  ? ?  ? ? ?....
33 34 35  ? ?  ? ....
36 37 38 39 40 41 42 43 44 45 46
...

once I click 'OK' ,  rapidminer will prompts me a 'error Message:'

Message: An attribute 2 was specified for column 2, but this column does not exist in input data.

What I want is a integer array for these data, How can I deal with it ? ??? ??? ???

Thanks in advance.
