 * Other projections to try are:
-	* `PDOS : Si1;Si2(s)`  -- Output the PDOS on Si atom 1 and the PDOS on the s-channel of Si atom 2. (Resulting in two projectors)
+	* `PDOS : Si1(s);Si2(s)`  -- Output the PDOS on Si atom 1 and the PDOS on the s-channel of Si atom 2. (Resulting in two projectors)
 	* `PDOS : sum:Si1-2(s)`  --  Output the sum of the s-channels on the two Si atoms. (Resulting in one projector)
 	* `PDOS : Si1(p)` -- Output the p-channel on Si atom 1. (Resulting in one projector)
