getTrain

public Alignment getTrain()

Returns the training alignment. This will return each time a new copy of the alignment such that changes to this object will not be reflected in multiple calls to this method.

Returns:

training alignment

getTest

public Alignment getTest()

Returns the test alignment. This will return each time a new copy of the alignment such that changes to this object will not be reflected in multiple calls to this method.

Returns:

test alignment
