[ncl-talk] how to tell readAsciiTable to ignore ^M ? apply dos2unix once or more times

[xiaoming Hu]

Hello Stavros

You are right, if I do dos2unix, I remove one ^M at each line, and do another dos2unix and remove the other ^M at each line.
So to be safe, I probably need to do once or twice dos2unix before I readAsciiTable

Thanks a lot!
Xiaoming

Hi Xiaoming,

It seems that you are trying to read a file DOS line endings. You must convert it to Unix type, so I suggest using a software like dos2unix:
http://dos2unix.sourceforge.net/

There are plenty of other ways of converting the file. Then NCL will read the file without problems.

Good luck!

Hello
  I have trouble to readAsciiTable   the following data:

see:
ncl 8> data_second = readAsciiTable("Z_UPAR_I_54342_20130712111513_O_TEMP-L.txt.SECOND", 12, "float", 7)
warning:asciiread: End of file reached and only (76173) elements were read from the file, filling remaining elements with the default missing value for the requested type
ncl 9> print(data_second(:2,0))


Variable: data_second (subsection)
Type: float
Total Size: 12 bytes
            3 values
Number of Dimensions: 1
Dimensions and sizes: [3]

Number Of Attributes: 1
  _FillValue : 9.96921e+36
(0) 2.013071e+13

(2) 70

It appears NCL  treated   ^M^M   as an additional line.
How can I tell NCL to treat ^M as characters?
Thanks
Xiaoming
