The knowledge of the path to the objects that need to be misaligned is essential since there is no other way of identifying them.

One can however create 'symbolic links' to any complex path to make it more representable for the object it designates:

TGeoPNEntry *pne = new TGeoPNEntry("TPC_SECTOR_2", "path_to_tpc_sect2");

pne->SetPhysicalNode(pn)

Such a symbolic link hides the complexity of the path to the align object and replaces it with a more meaningful name. In addition, TGeoPNEntry objects are faster to search by name and they may optionally store an additional user matrix.

For more details please read the misalignment section in the Users Guide.
