OPTIONS

       Input

       •   STDIO: Use standard input/output streams

       •   InpAux: Input structures in InChI default aux. info format (for use with STDIO)

       •   SDF:DataHeader: Read from the input SDfile the ID under this DataHeader

       •   START:n: Start at n-th input structure

       •   END:n: Stop after n-th input structure

       •   RECORD:n: Treat only n-th input structure

       •   AMI: Allow multiple input files (wildcards supported)

       •   AMIOutStd: Write output to stdout (in AMI mode)

       •   AMILogStd: Write log to stderr (in AMI mode)

       •   AMIPrbNone: Suppress creation of problem files (in AMI mode)

       Output

       •   NoLabels: Omit structure number, DataHeader and ID from InChI output

       •   NoWarnings: Suppress all warning messages

       •   AuxNone: Omit auxiliary information

       •   SaveOpt: Save custom InChI creation options (non-standard InChI)

       •   Tabbed: Separate structure number, InChI, and AuxInfo with tabs

       •   MergeHash: Combine InChIKey with extra hash(es) if present

       •   NoInChI: Do not print InChI string itself

       •   OutErrInChI: On fail, print empty InChI (default: nothing)

       •   OutputSDF: Convert InChI created with default aux. info to SDfile

       •   SdfAtomsDT: Output Hydrogen Isotopes to SDfile as Atoms D and T

       Structure perception

       •   SNon: Exclude stereo (default: include absolute stereo)

       •   NEWPSOFF: Both ends of wedge point to stereocenters (default: a narrow end)

       •   LooseTSACheck: Relax criteria of ambiguous drawing for in-ring tetrahedral stereo

       •   DoNotAddH: All H are explicit (default: add H according to usual valences)

       Stereo perception modifiers (non-standard InChI)

       •   SRel: Relative stereo

       •   SRac: Racemic stereo

       •   SUCF: Use Chiral Flag: On means Absolute stereo, Off - Relative

       Customizing InChI creation (non-standard InChI)

       •   SUU: Always include omitted unknown/undefined stereo

       •   SLUUD: Make labels for unknown and undefined stereo different

       •   RecMet: Include reconnected metals results

       •   FixedH: Include Fixed H layer

       •   KET: Account for keto-enol tautomerism (experimental)
