-xml VS -file in OpenSeesSP

[Luisa]

Do we still have to use -xml instead of -file in order to record responses in OpenSeesSP? Is the reason that the data columns in -xml are recognizable, while they are not in -file? Or is it because of the fact that the data recorded by -file is inherently incorrect and useless?! Thanks.

no. it should return the same results as if used sequentially.
