Convert Fingerprint to Bitvector

Schrödinger Nodes for Suite2019-1 version 0.0.1.447_cMf4_L312_13223318 by Schrödinger

Converts a Fingerprint to a Bitvector. By choosing to omit bits using the settings below, the performance of the node will increase by only including bits/columns that are sufficiently populated. Using 0% and 100% for the omit parameters below respectively may result in bitvectors that have a very large number of bits and may have a serious (negative) effect on performance.

Backend implementation

utilities/canvasFPBinary2CSV
canvasFPBinary2CSV is used to implement this node.

Options

Omit bits that are set by less than fraction
This value controls the columns in the output to exclude columns that have the percentage of rows set less than the percentage specified. Default: 1.0%
Omit bits that are set by more than fraction
This value controls the columns in the output to exclude columns that have the percentage of rows set more than the percentage specified. Default: 99.0%
Omit bits only set in single molecule
Omit bits set in all molecules
Force Binary Representation
If binary fp has been rescaled to continuous values, force binary (0,1) representation.
Include bits that are unset in all molecules
This option may consume large amounts of disk space and will be ignored unless the input FPs have been generated with reduced precision (reduced by at least 22 bits). All omit bits options will be ignored on selecting this option.
