Schrödinger Nodes for Suite2018-1 version by Schrödinger

Direct Principal Components generation without intermediate analysis

Backend implementation

The command line tool canvasPCA is used to implement this node.


Column containing binary fingerprint input
Choose the input column that has the binary fingerprint input
Use binary fingerprint input
This option is enabled only if there exists a binary fingerprint in the input table. If checked, the binary fingerprint is used as input. Otherwise, the input used is a csv table, which is the molecule names and any number of numerical data columns.
Include Molecule
Whether the molecule should be included in the output
Include Input
Whether all columns in the input should be included in the output
Number of Principle Components
Number of Principle Components to use. Default is 2.
Retain the # most informative bits
keep only the # most informative bits across the chosen input set,when using a binary fingerprint input.
Scales each dimension to unit variance if it is within certain threshold.
Threshold for scaling. 1E-3 as default.

Input Ports

The input should include molecules (in Maestro or SD) and any number of numerical data columns or a binary fingerprint data

Output Ports

The output includes the principle components computed plus the input, if specified (i.e., the molecule or all columns)
