OEMatchedPairTransformExtractMode¶

This namespace contains constants that control transform generation during retrieval from the matched pair index.

Unspecified

This value indicates an unspecified or null mode value.

Forward

This mode requests that only forward direction transforms be returned where ‘forward’ indicates the direction of earlier indexed structures over later indexed structures.

Backward

This mode requests that only backward direction transforms be returned where ‘backward’ indicates the direction of later indexed structures over earlier indexed structures.

NoSMARTS

This mode suppresses the addition of SMARTS qualifiers to the transformation which is present to ensure more accurate application of the transformation. If the transform is being used for purposes other than performing transformations, the suppression of SMARTS qualifiers may provide simplification for downstream use of the transformation information.

NoIsotopes

This mode suppresses isotopic information in the transformation to allow more general use of the transformation with mixed isotopic input structures.

Sorted

Since the direction of the transformations returned is dependent on input order of the indexed structures, this mode attempts to perform a simple sorting of the right hand and left hand sides of the transformation to collapse forward and backward transformations to a more deterministic form.

NoMatchedPairs

This extraction mode suppress populating the transformations with matched pair id information, for example, if the transformation itself is the only information of interest.

NoMatchedPairData

This extraction mode suppress populating the delta data for the matched pairs in the returned transforms, for example if the transformation and the matched pair ids are all that is required.

This extraction mode requests that attachment point information be added to the returned transforms to indicate the number of neighbor atoms adjacent to the desired context atoms.
