Hi ferreters,
I have encountered a problem when I open multiple identical datasets.
I can see that time axis are not defined for each dataset but shared.
It is a strategy.
But as a consequence, if I apply a change on a axis (for example a 10 days offset on the 1st one) then
other variables that share the time axis get this offset as well.
Is there a way to force ferret to define a unique time axis for each dataset ?
Below a simplified script that shows the problem.
!==============================================================================
cancel data/all; cancel var/all; cancel axis/all
use http://vesg.ipsl.upmc.fr/thredds/dodsC/work_thredds/p86pasb/IPSLCM6/PROD/midHolocene/CM61-LR-H6k-03/MONITORING/files/ATM_t2m_global_prio_ave.nc

let var=T2M_GLOBAL_PRIO[L=@SBX:120]
show axis `var[d=1], return=taxis`
show axis `var[d=2], return=taxis`
let tt = t[gt=`var[d=2],return=taxis`]
define axis/t/t0="`var[d=2],return=t0`"/units="`var[d=2],return=tunits`"/calendar="`var[d=2],return=cal`" `var[d=2],return=taxis` = tt + `10*24*60*60`
show axis `var[d=1], return=taxis`
show axis `var[d=2], return=taxis`

I get a note from ferret telling
Replacing definition of axis TIME_COUNTER
*** NOTE: grid GOO1 used by data set ATM_t2m_global_prio_ave
*** NOTE: Redefinition may alter apparent contents of data set
*** NOTE: grid GOO2 used by data set ATM_t2m_global_prio_ave
*** NOTE: Redefinition may alter apparent contents of data set
How could I do then to apply an offset on the 2nd dataset without modifying the 1st one ?
Thanks
Patrick
