readVectorFile

protected void readVectorFile(java.lang.String vectorFileName,
                              boolean sparse)

Description copied from class: SOMLibSparseInputData

Reads the input data from the given file, which has to follow the Input Vector File specification. Additionally calculates the AbstractSOMLibSparseInputData.meanVector and creates the AbstractSOMLibSparseInputData.nameCache for faster index search.

Overrides:

readVectorFile in class SOMLibSparseInputData

Parameters:

vectorFileName - the name of the input vector file.

getFileNameSuffix

public static java.lang.String getFileNameSuffix()

getFormatName

public static java.lang.String getFormatName()
