[ncl-talk] reading binary file

[Dennis Shea]

The files you sent re two different sizes (bytes):

  20736000 Jun 19 06:55 viirs_dbdi_gridded_statis2013212.dat
    8294400 Jun 19 06:55 viirs_meandbdi_gridded_statis2015032.dat

Your read code:

       setfileoption("bin","readbyteorder","bigendian")
       var1 = 1e-9 *
tofloat(cbinread("./Feb/viirs_meandbdi_gridded_statis2015032.dat",(/5,720,1440/),"uint"))
       var2 = 1e-9 *
tofloat(cbinread("./Jul/viirs_dbdi_gridded_statis2013212.dat",(/5,720,1440/),"uint"))

indicates the two files should be the same sizes

      N = 5*720*1440*4    ; 4 bytes per integer

      N = 20736000

So something is wrong with the viirs_meandbdi_gridded_statis2015032.dat file
