Reads and writes V2000 and V3000 versions
| s | determine chirality from atom parity flags This is valid only for 0D information. Atom parity is always ignored on reading for MOL files containing 2D or 3D information. |
| T | read title only |
| P | read title and properties only When filtering an sdf file on title or properties only, avoid lengthy chemical interpretation by using the T or P option together with copy format. |
| 3 | output V3000 not V2000 (used for >999 atoms/bonds) |
| m | write no properties |
| w | recalculate wedge and hash bonds(2D structures only) |
| A | output in Alias form, e.g. Ph, if present |
