# sdf-to-smi(1)

convert SDF to SMILES

## NAME

sdf-to-smi - convert SDF to SMILES

## DESCRIPTION

USAGE

-

  sdf-to-smi \[\<args\>\] \[\<files\>\]

DESCRIPTION

-

  sdf-to-smi converts SDF files into SMILES.

OPTIONS

- **--convert-type-8-bonds-to-covalent**

  convert all type 8 bonds to single covalent bonds

- **--no-adjust-charges**

  do not adjust atom charges when converting type 8 bonds

- **--no-estimate-attached-hydrogens**

  do not estimate the number of attached hydrogens

- **--ignore-flat-tetrahedra**

  when considering tetrahedral chiral centers, ignore flat tetrahedra (based on volume threshold) \[default\]

- **--require-tetrahedral-angles**

  when considering tetrahedral chiral centers, ignore tetrahedra with average bond angle far from 109.5 degrees

- **--planarity-threshold** NUM

  planarity volume threshold in cubic angstroms; tetrahedra with chiral volume less or equal to the given one will be understood as flat \[default: 1e-06\]

- **--normalise-vectors**

  normalise vectors used for chiral volume calculation

- **--mark-square-planar-centers**

  mark chirality in square planar centers

- **--no-generate-racemates**

  do not attempt to fully represent racemates in non-Sohncke space groups

- **--remove-excess-stereochemistry**

  remove excess stereochemistry settings (experimental)

- **--help**
