Hi all,
I have one question on reading a binary data, the format of binary data:
One-byte (scaled, unsigned integer) flat binary arrays preceded by a
300-byte header, no byte order/endianness.
Part of my script:
  fin = "./conc/nt_200801_f17_v01_n.bin"
;--read header--;
  head = fbindirread(fin, 0, 300, "character")
;---read data--;
   bdata = fbindirread(fin,0,(/ NY,MX /),"byte")
   data = byte2flt(bdata)
   printMinMax(data, True)
Then, the output shows the range: -127~128. While, in data document, the
range is 0~255. Will be something wrong in my script?
Thanks a lot in advance!
