Rather than writing out the molecule as a PDB file, it is probably
better to write out all the datablocks associated with the current
molecule, because then you preserve any other datablocks you may have
created from the same molecule. You can do that like so:
write ${.id_m}_* .undo.pdb ;
remembering that ${.id_m} is a variable that records the name of the
last clicked molecule. Put that in the @yes macro instead of pdb_write
and put the following line in the @undo macro:
read .undo.pdb
instead of the pdb_read line. Please be aware though, that these macros
may have undesired side-effects if you have several molecules in your O
session, and you are clicking at both of them! Of course you can
hardwire the molecule name...
Cheers,
Morten
