erros when building asbhl20

I'm using Matlab R2014b, when I built the asbhl20 model, there was an error as following: 'asbhl20/Variant/Previously saved data/From File' does not support timeseries input in this code generation mode. Consider converting the timeseries data into the array format. For information about the valid array format, see the documentation for the From File block. Could anyone tell me how to translate the timeseries to array format? Thanks!
