Hi Dehui,
What about my previous suggestion to use dummy variable that indicates time
periods (fixed values 0, 1,2,3...N) for N
Great, thanks

Try MarkusN's r.regression.series in the addons for grass7. It
Good suggestion, and coincidentally I was just looking at it. Am I correct
to assume that to mimic the calculation of slope etc in r.series, I would
need to create a second time series of 'dummy' maps with values 0 for first
time period, 1 for second time period, etc.? I did this in R and it gave
