Re: [ferret_users] **ERROR Ferret crash; signal = 11

Hi,

That's a rather large amount to save in one go.  Over 5e8 values in one 
slab or (as ferret uses double precision) 4GB!

I would break up the save as follows

save/l=1:50/clob/file=rain.nc rain
repeat/range=51:4401/name=ll save/app/file=rain.nc rain[i=`ll`:`ll+49`]

Also since the input file appears to store rain as a real*4 float you 
may want to set the output to be FLOAT

set var/outtype=float rain

before saving.

You will almost certainly need to change the type of netCDF file that 
gets written to 64BIT_OFFSET or netcdf4. Classic format can't store more 
than 2GB. The first line above will need to be

save/l=1:50/clob/file=rain.nc/ncformat=64BIT_OFFSET rain

or

save/l=1:50/clob/file=rain.nc/ncformat=netcdf4 rain





Cheers,
Russ
