Hi all,
I have a time series (annual values) of a variable GPP, with L as a time axis and J as the land surface model axis (19 models). I want to shift the variable GPP by N years on its
time axis. I tried using the transformation l=@SHF with a shift of `itau` but it doesn’t work as itau is a vector on the J axis, itau being model dependent. I tried let GPP_lag = GPP[l=@SHF:-`itau`] but ferret doesn’t allow it. See below: yes? list itau VARIABLE : INT(TAUEXG_NOW + 0.5) - OFFSET SUBSET
: 19 points (Y (model)) X
: 0.5 to 2.5 TIME
: 05-DEC-2010 12:00 to 02-DEC-2020 12:00 1

20.00 yes? yes? let gppG_lag=gppG[L=@SHF:-`itau`] **ERROR: invalid command: grave accent doesnt evaluate to scalar itau Any suggestion on how to shift the time axis of a variable with the shift value itau being a vector, not a scalar, would be really appreciated.
