SBC Binary File Structure

The binary file is organized in the following sections.

1. Endianess (4 bytes, uint32)

   • Used to indicate little or big endian.
   • Written as a hexadecimal constant (0x01020304 for little, 0x04030201 for big).

2. Header Length (2 bytes, uint16)

   • Size of the next segment (the Data Header) in bytes.

3. Data Header (variable length)

   • Contains semicolon-separated entries of the form:

     {column_name};{dtype};{dim1},{dim2}...
     

   • Dtype can be “int32”, “double”, etc.
   • Dimensions (e.g., “[3, 2]”) define the shape of each data element.

4. Number of Lines (4 bytes, int32)

   • Total number of records in the file when known.
   • Set to zero for an open-ended file.

5. Data Lines

   • Each line is a concatenation of binary values for each column.
   • Each column is written in the correct dtype and shape specified in the header.
