Hi Estanislao

no its not mandatory but if you are facing problem in plotting as sometime our machines getting bit slow or hangs so you can use set mem/size command before you start plotting. it will relax your ram for further plotting/calculation.

regarding multiplot animation you can use the link where i put all the details and necessary steps for doing this task.

Hi Estanislao,

Paulo is correct but use can add few more thing in this command like time step size and memory size.

repeat/l=2191:4380:1 ( save/append/file=normal.nc sossheig; set mem/size = 1000 )

l=2191:4380:1 (here one is the time step size) and  1000 is the memory size (adjustable)

it will free your memory at every step to make a faster process. you can adjust the memory size according the configuration of your machine i.e. whether it will go above  1000 or it has lower then 1000.

please mail us back if you have any problem for this.

regards, saurabh

Estanislao,

Use a repeat loop and save/append... eg:
repeat/l=2191:4380 ( save/append/file=normal.nc sossheig )

You also might want to control if the data is to be saved in single or double precision ( http://ferret.pmel.noaa.gov/Ferret/documentation/users-guide/commands-reference/SET#_VPINDEXENTRY_setlist_outtype )

Cheers,

Dear Community,


I have I heavy nc file (5.3 GB) where I want to select an interval and save in a new nc file in order to make it lighter. But It excess the memory setting. I have tried to adjust the memory but it is never enough. I am using this command.

 SAVE/FILE=normal.nc/L=2191:4380 sossheig



Is there any alternative way to save this file or avoid this error?


Thanks so much for your time.


Kind regards,


Estanislao
