All 89 arrays are from the same print-run with the same array layout 
information,I think it is because my computer's RAM is only 256 RAM, I am in 
the processing of upgrade my RAM to 1 Gb now. However, I am able to read 12 
arrays at one time, however, I got the following warnings, maybe that is why I 
got so many NA values.
Warning messages:
1: number of items read is not a multiple of the number of columns
2: NAs introduced by coercion
3: NAs introduced by coercion
4: NAs introduced by coercion
5: NAs introduced by coercion

Could you please give me any suggestion?
Thanks
