Hi Adam:
Thanks for your help!
I found my problem. The text file contains some string.
Cheers!Ed

 Hi Ed,
First of all, version 6.0.0 is over 5 years old so we highly recommend you upgrade to the newest version (6.3.0). This is likely not the cause of the issue though.

As far as I know asciiread does not have a limit on the size of the file or on the dimensions of the data array. 

Does your ascii file contain anything other than float values? Also, what happens if you read in the data with a (/-1/) as opposed to (/mn,ml/), do you get all the data?

As always when you respond please include the ncl-talk email list in your reply.
Adam

  Dear Sir/Madam:I have a text file with 13376 col. I used the following script to read:------------------------------------------------------------------------------------------------------------
mn = numAsciiRow("NIWA_Haast_20140624.dat")
ml = numAsciiCol("NIWA_Haast_20140624.dat")
data = asciiread("NIWA_Haast_20140624.dat", (/mn,ml/),"float")
print(mn)
print(ml)
print(data(mn-1,10))------------------------------------------------------------------------------------------------------------

After ran the script, I got:
----------------------------------------------------------------------------
Variable: mn
Type: integer
Total Size: 4 bytes
            1 values
Number of Dimensions: 1
Dimensions and sizes:   [1]
Coordinates:
(0)     13376
Variable: ml
Type: integer
Total Size: 4 bytes
            1 values
Number of Dimensions: 1
Dimensions and sizes:   [1]
Coordinates:
(0)     21
Variable: data (subsection)
Type: float
Total Size: 4 bytes
            1 values
Number of Dimensions: 1
Dimensions and sizes:   [1]
Coordinates:
Number Of Attributes: 1
  _FillValue :  9.96921e+36
(0)     9.96921e+36
------------------------------------------------------------------------------------------------------The data(mn-1,10) is not a missing value. Actually, more than 100 col numbers from the end of the file were not read correctly. What is the problem? I used nclv.6.0.0What is the maximum value of the column of a text file allowed in asciiread?
Thank you very much!
RegardsEd
