[ncl-talk] warning during read ascii file

[Dennis Shea]

seismic = asciiread(ascii_filename,(/725,6/),"float")

6*725   =4350 elements

Maybe, the file has fewer rows?

   2984/6 = 497.333    This should be an integer

   https://www.ncl.ucar.edu/Document/Functions/Contributed/numAsciiRow.shtml

==========
  ncol      = 6
  nrow     = numAsciiRow(ascii_filename)
  print("nrow="+nrow)

  seismic = asciiread(ascii_filename,(/nrow,ncol/),"float")

=========
Are there hidden characters in the file?
