This file provides a hypothetical binary-level representation of how an mmCIF data block might be structured and stored in memory, using an abstract binary model for educational purposes.
Data Block Header:
01001101 01001101 01000011 01001001 01000110
# "mmCIF" in ASCII binary, each 8-bit segment represents a character
Loop Structure:
01001100 01001111 01001111 01010000
# "LOOP" in ASCII binary
# Below are example binary encodings for a few _atom_site fields
# Assuming simple direct encoding of field identifiers and coordinates
_atom_site.id → 00000001 # Identifier for the atom
_atom_site.type → 00000010 # Atom type (e.g., C, N, O)
_atom_site.coord_x → 01000000 00000000 00000000 00000000
# x = 2.0 (float), simplified IEEE 754 single-precision example
_atom_site.coord_y → 01000000 00100000 00000000 00000000
# y = 2.5 (float)
_atom_site.coord_z → 01000000 01000000 00000000 00000000
# z = 3.0 (float)
