Reading 1-byte binary data (type=i1)

["Paulo B. Oliveira" <pbo@xxxxxxxxx>]

Hi all,

I'm trying to read binary SST data files derived from satellite data.
Each gridpoint (pixel) is stored as 8bit unsigned char (range: [0,255]).

Reading the file with:

file/var=sst/format=stream/type=i1 datafile

variable SST is in the range [-127,127].

Is there a way to force ferret to interpret each byte as unsigned ?

Regards,

Paulo.
