+<note tip>We may be interested in the visualisation of the electronic density. Copy the ''ethanol.inp'' into ''ethanol_dens.inp''.</note>
+Add the following sections:
+**under &DFT**
+<code cp2k>
+       &PRINT
+          &E_DENSITY_CUBE
+          &END
+       &END
+       &SCF
+          SCF_GUESS RESTART
+       &END
+</code>
+This tells to read the old wavefunction and to print the cubefile of the density.
+At the end of the input file:
+<code cp2k>
+&EXT_RESTART
+     RESTART_FILE_NAME ./c2h6o-1.restart
+&END
+</code>
+Then, change ''RUN_TYPE GEO_OPT'' to ''RUN_TYPE ENERGY'' to only run a single point calculation. It will generate a cubefile with the density which you may visualize with VMD.
