Re: appending netcdf.Is there limit in number of files.



Hi all,
There can be 5000 stepfiles in a descriptor file, so this is a good solution.
You should also be able to open a file, append its data to the master file,
and then cancel the file before going on to the next, as in this message from
Rob Scott last week.

Takaya,

Are you opening the files one at a time? Since you are dealing with a time series, you may want to try
using a Ferret descriptor file to connect the files together so that Ferret sees them as one data set.
The details for descriptor files can be found in the Ferret documentation in Ch. 10 Sec. 4. I currently
use a descriptor file connecting 120 files so I know they can get at least that far.

Dear Sir

If there is a limit of number for appending netcdf files,
could you tell me how to solve my case?

I have 240 monthly data netcdf files of sst from 1985 jan.
to 2004 dec. like

     currently SET data sets:
    1> ./sst198501.nc  (default)
 name     title                             I         J   
     K         L
 SSTXY    SST[G=XYGRID@ASN]                1:684     1:684
    ...       ...
  

sst198501.nc
sst198502.nc
sst198503.nc
.
.
.
sst200410.nc
sst200411.nc
sst200412.nc

(all together 240 files)

I would like to make it one netcdf file with those files
above by appending.

Best Regards,

Takaya Namba

Hi

When I append the netcdf file, the error comes as
below

add_connect: too many connects, cannot add another.

After 32 files got appended, this error happened.

is there number of limit for appending files?

Best Regards,

Takaya Namba
