[ncl-talk] Supported file types for asciiread

[Ryan Connelly]

Hi all,

Trying to read in sounding data that I have in a .txt file using the
asciiread function (
https://www.ncl.ucar.edu/Document/Functions/Built-in/asciiread.shtml):

f = addfile("../2016020512_sounding.asc","r")

  data_obs = asciiread(f,-1,"string")               % Loads text file
  p_obs = tofloat(str_get_field(data_obs,1,"     "))    % Reads in first
column, which is pressure in hPa
etc...

But I get:

warning:["FileSupport.c":3026]:NCL does not know anything about file suffix
<txt>.
But NCL will try its best to figure out the file format.

fatal:An internal error has occurred. The file format requested does not
appear to be supported, could not open (../2016020500_sounding_OKX.txt)
fatal:Argument type mismatch on argument (0) of (asciiread) can not coerce


Even the examples on this page use .txt files, and I've tried .asc and .csv
with the same error message, so what is the problem here?

Ryan
