Save and open Files
Choose files saved prior to version 2.0 of MoleculeSketch that you wish to convert to the new file format. This can be usefull, if you want to edit your old files with the iPad App.
Import Mol Files
Import structure file (mol, sdf, txt) that follow the V2000 format
Export sketches directly as JPEG/JPG, PNG or PDF file
Show/Hide all C-Atoms
Decide, if all carbon atom labels should be shown
Show/Hide all missing hydrogen atoms
Decide, if hydrogen atoms should be added where possible
Show non bonding electron pairs
Enable or dissable the placement of non bonding electron pairs on heteroatoms.
Enable/Dissable position helper
When drawings bonds the position of the bond is locked on some positions
Enable/Dissable warning for to many bonds
Show or hide a warning if an atom has to many bonds.
Calcuculate the chemical formule of an atom selection.
Calculate average mass
Calcuculate the average mass of an atom selection.
Add explicit hydrogen atoms
Adds explicit hydrogen atoms on atoms with free valences. The addition can be restricted by selection.
Remove explicit hydrogen atoms
Removes explicit hydrogen atoms. The removal can be restricted by selection.
Separate selected Atoms from current molecule assignment. Can be used if imported structures contain separated molecules but are automatically assigned as one molecule.
