Re-plotting detrended data series

[PsyDr]

does anyone know how to obtain the raw data series (not just a graph) after applying detrending techniques such as the holts winters, Koehler, or springer in mattlab/excel/spss? I can easily apply the former and get graphs. Can't seem to pull the data out for other purposes.

Traditional linear regressions and such wont work here.

I'm missing something.

Apologies if I'm missing something, but can't you just get an output of the residuals and extrapolate the (new) raw values from there?
