pickrec | Pick data records referenced by a classified data |
-c <cldata> | classified data for pointing records |
-d <data> | source data |
-dout <trgdata> | result data |
This operation picks a subset of data records from <data>. The records to be picked are pointed to by the indexes in <cldata>. Typically this command is used to restrict the analysis scope to certain data records, which have been chosen to some neuron(s). With mergecld (see 3.7) such a classified data can be formed, which contains the indexes of data records chosen to several neurons.
Example (ex3.2): This example shows the necessary commands and phases needed to restrict scope to some part of the original data using a TS-SOM. select is used to select two groups g1 and g3, which could be analyzed in more detail in the second phase.
