transformnode properties

Table node icon The Transform node allows you to select and visually preview the results of transformations before applying them to selected fields.

Example

stream = modeler.script.stream()
typenode = stream.findByID("id42KW3MSA94B")

node = stream.create("transform", "My node")
stream.link(typenode, node)

node.setPropertyValue("fields", ["Age", "K", "Na"])
node.setPropertyValue("formula", "Select")
node.setPropertyValue("formula_log_n", True)
node.setPropertyValue("formula_log_n_offset", 1)

node.run([])

Note: Many of the properties listed in the following table are only supported in SPSS Modeler Desktop, not in SPSS Modeler in watsonx.ai Studio.

Table 1. transformnode properties
`transformnode` properties	Data type	Property description
`fields`	[ field1… fieldn]	The fields to be used in the transformation.
`formula`	`All` `Select`	Indicates whether all or selected transformations should be calculated.
`formula_inverse`	flag	Indicates if the inverse transformation should be used.
`formula_inverse_offset`	number	Indicates a data offset to be used for the formula. Set as 0 by default, unless specified by user.
`formula_log_n`	flag	Indicates if the log_n transformation should be used.
`formula_log_n_offset`	number
`formula_log_10`	flag	Indicates if the log₁₀ transformation should be used.
`formula_log_10_offset`	number
`formula_exponential`	flag	Indicates if the exponential transformation (e^x) should be used.
`formula_square_root`	flag	Indicates if the square root transformation should be used.
`use_output_name`	flag	Specifies whether a custom output name is used.
`output_name`	string	If `use_output_name` is true, specifies the name to use.
`output_mode`	`Screen` `File`	Used to specify target location for output generated from the output node.
`output_format`	`HTML` (.html) `Output` (.cou)	Used to specify the type of output.
`paginate_output`	flag	When the `output_format` is `HTML`, causes the output to be separated into pages.
`lines_per_page`	number	When used with `paginate_output`, specifies the lines per page of output.
`full_filename`	string	Indicates the file name to be used for the file output.
