| addcld | Create an empty classified data |
| -c <cldata> | name of the classified data |
| addcl | Add a new class to classified data |
| -c <cldata> | classified data |
| -cl <class> | name of the new class |
| updcl | Update a class by an identifier |
| -cl <class> | name of the class |
| -id <id> | an identifier |
| cpcld | Copy a classified data frame |
| -c <cldata> | source frame |
| -cout <cldataout> | target frame |
| cpcl | Copy a single class |
| -cl <class> | source class |
| -cout <cldata> | target classified data |
| -clout <classtrg> | target class |
| shftcld | Shift indexes in a classified data |
| -c <cldata> | source classified data |
| [-id <shift-id>] | the number to be added to indexes |
| [-cout <cldata>] | target classified data (source is used, if this is omitted) |
These commands are meant for handling classified data frames. addcld creates an empty classified data frame. addcl creates a new empty class to a classified data. updcl updates a class with an identifier. The identifier is created to the class, if it does not exist, otherwise the identifier is removed from the class. shftcld adds a constant index to all the indexes in a classified data (or 0 if -id is omitted).
Example (ex2.2): A typical use for these commands is grouping of SOM neurons. The whole grouping is placed into a classified data frame, in which each class corresponds to one group of neurons.
NDA> somtr... ... NDA> addcld -c groups NDA> addcl -c groups -cl goodAp NDA> updcl -cl groups.goodAp -id 14 NDA> updcl -cl groups.goodAp -id 16 NDA> addcl -c groups -cl badAp NDA> updcl -cl groups.badAp -id 17 # Remove 17 from badAp NDA> updcl -cl groups.badAp -id 17
Example: Normally, the grouping is not performed manually but with the graphical user interface (GUI). The following command sequence describes, what happens behind the GUI.
The identifiers of the neurons are got from a graphical image by the commands fndpnt and fndreg (see section 7.13.2). This can also be invoked by runevent (see section 7.13.3). Typically the coordinates for these commands are got from a mouse event. First you should run the example `ex7.4' and then apply the following commands:
... # When a window is opened: # Create a grouping and a group (if they do not exist) NDA> addcld -c som1Grp NDA> addcl -c som1Grp -cl goodAp ... # A mouse click event causes the following commands to be run: # For updating a single neuron to current group NDA> fndpnt grp1 0.3 0.4 # -> neuron id = 8 NDA> updcl -cl som1Grp.goodAp -id 8 ... # A mouse choose_region event causes the following commands: # For updating a region of neurons to current group NDA> fndreg grp1 0.1 0.1 0.5 0.1 0.5 0.5 0.1 0.5 # -> neuron ids = 8, 6, 5, 7 NDA> updcl -cl som1Grp.goodAp -id 6 NDA> updcl -cl som1Grp.goodAp -id 5 NDA> updcl -cl som1Grp.goodAp -id 7
