A cmp on the two files says there are differences, and using a hex editor confirms this. The file produces a simple error when using "open.ncdf" and in fact the ncdump utility pr...

Hi all -- I am working on 64-bit Windows XP. I'm not a very technical person when it comes to the command line stuff, so please forgive me if this is a stupid question. I have a bunch of HDF files, and I want to dump a single PM25 data layer from each file to .txt by invoking ncdump.exe from system(). Here's a sample command string: "C:/ncdump -v PM25 C:/01aug2010.hdf > C:/01aug2010.txt" This works perfectly in Python, but does not actually generate the .txt file in R when: system(command) It does show the output on the console, if flagged to do so, and I...

...and complex * the examples above hand-craft their output files So I'm wondering, can anyone point me to, or provide, code that copies a netCDF file both * completely: all coordinate variables, all data variables and their attributes, and all global attributes, such that $ diff -wB <( ncdump -h source.nc ) <( ncdump -h target.nc ) | wc -l 0 * programmatically: no or minimal hand-coding of, e.g., attribute names and values, missing-value value. ? If not, can this be done in principle, or are there steps that must (at least currently) necessarily be hand-coded? TIA, Tom Roche &lt...

Can someone help me out with a "small" problem? I've started using netcdf files recently, and I want to extract the grid id and also the coordinates from a HIRHAM netcdf file. I know how to extract a slice of dataset both in space and in time and I also know the area that this file should cover, however I have no idea regarding the reference for both LAT/LON and RLAT/RLON. I tried

(At least, after nc_sync(netcdf.file), the file `ncdump -h`s properly.)

Hello I am a new user of R . and I ve problem with R and netcdf . I succed installation , I could use all examples . But when I take my netcf it is different .

Dear all, I have a file which I've converted from NetCDF (.nc) to text (.txt) using ncdump in Unix (as I had problems using the ncdf package to do this). The first few rows (as copied and pasted from the Unix console) of the file appear as follows: _, _, _, _, _, _, _, _, _, _, _, _, _, _, _, _, _, _, _, _, _, _, _, _, _, _, _, _, _, _, _, _, _, _, _, _, _, _, _, _, _, _, _, _, _,...

Hello, I have been having difficulties opening netcdf files using the netcdf library. I am able to successfully open the file and I can determine the names and size. However, when I try to read it I receive an error. Reading the documentation, I am wondering if this might be due to a difference between netcdf version 2 and more recent netcdf format? I've tried using different values for the

Lately I am publishing in a journal that is very picky about their graphics formats. It is more efficient for me to get the final picky details
