Cleaning options in Marvin

Both 2D and 3D options can be divided into two groups: Base and Extra. Base contains the typically used options which are also accessible via "Edit/Clean" menu in Marvin. You can use them in each case. Extra includes further options which are accepted only by the MolConvert application and the clean method of MoleculeGraph in the Marvin Beans API.

2D options

• Base:
• Extra:

  e Keep verbose either flag
  

  If it is not possible to decide whether the double bond is CIS or TRANS, the double bond either flag (crossed double bond) is kept.
  Otherwise, the flag is removed and converted to double bond with a wiggly bond.

  E Error output:

  0 - no output
  1 - error output to standard error (default)

  d show debugging info

  tX set time limit to X ms
  

  maximum time spent in the cleaning
  default value: 20000ms
  if X<1, no time limit used

  p ignore parity setting
  

  do not set wedges, the parity information is lost.

  T{filename} ring system template file name
  

  Use the template file during ring system cleaning together with the local template file definition (which is located at the users home directory .chemaxon/cleantemplates.t).

3D options

• Base:

  S{fine} Find low energy conformer. Leave failed fragments intact.

  S{fast} Fast clean, if failed, perform fine clean, accept any generated structure (default)

  Notes: null always specifies the default value. O0 and OD are deprecated. They use the default value.

• Extra:

  ? Print the complete list of options to System.err. The same list can be printed by invoking the MolConverter with the -H3D option.
  

  S{nofaulty} Same as S{fast}, but leave failed fragments intact.

  S{conformers} Generate conformers, store the calculated conformer coordinates and energies in PropertyObjects.

  E Store calculated Dreiding energy in SDF property string. The Dreiding energy for each fragment will be calculated in the last step.  Their sum will be stored in the sdf property called "Energy".
