in reply to read + unpack

read the following 6 values which are 3 doubles (8bytes), 2 long integer (4bytes) and another double (8bytes again)

For double precision floats use the d template in unpack, you are using f which is for single precision floats. See pack for details

    I did: in fact, I tried to "guess" the right combination of data files with many attempts but I never got a good result. I was also wondering how little-endian or big-endian system can change the way I have to read the file and how I can understand whether my system is littleendian or bigendian
    Thanks for the suggestions.
