-    """
-    Convert a canonical contact ID back to a global electrode index.
-
-    This is the inverse of `_build_canonical_contact_id`. For multi-shank probes,
-    the global index is ``shank_id * electrodes_per_shank + local_electrode_id``.
-
-    This formula works because the neuropixels-pxi plugin assigns electrode indices
-    in left-to-right, bottom-to-top, left-shank-to-right-shank order (confirmed
-    by Josh Siegle). Shank 0 owns indices 0 to electrodes_per_shank-1, shank 1
-    owns the next block, and so on.
-
-    Parameters
-    ----------
-    contact_id : str
-        Canonical contact ID, e.g. "e123" or "s2e45".
-    electrodes_per_shank : int
-        Number of electrodes per shank (cols_per_shank * rows_per_shank).
-
-    Returns
-    -------
-    int
-        Global electrode index.
