I’ve just read in the NetCDF’s release notes the following, for the 4.1.3-beta1 version from 2011-04-29:“Took out --with-hdf5 and related options due to high cost of maintaining this non-standard way of finding libraries.” Now, to the facts:1. this option forces people with custom HDF5 libraries to manually change CFLAGS, FCFLAGS and LDFLAGS in compile time.2. NetCDF 4.1.3 requires HDF5 1.8.6 3. Current linux distros comes with just HDF5 1.8.4Result: You removed the option to select HDF libraries when it would be most needed as everyone is needing to install custom HDF5 library on their computer. This makes people lifes a lot harder, you know? I am planning on shipping NetCDF and HDF5 as nested packages with a project we are doing due to excessive compile problems, and we will be forced to add back AC_WITH_ARG for HDF5 in NetCDF provided package, in order for it to work in accordance with the main package’s arguments.And, why did you call the AC_ARG_WITH option a non-standard way to find libraries? I thought it was a standartizing attempt from GNU autotools to aid in linking to packages...- fabricio From: Erik Noble Sent: Tuesday, August 02, 2011 10:52 AM To: Ashish Cc: netcdfgroup@xxxxxxxxxxxxxxxx Subject: Re: [netcdfgroup] ASCII to NetCDF Spazm, Go here http://www.ncl.ucar.edu/Applications/list_io.shtml and here http://www.ncl.ucar.edu/Applications/read_ascii.shtmlan you should be able to find the function that will work for you. It will probably be readAsciiTable You will have to tailor it to work with your file. There are many examples to follow on that page.-Erik On Aug 2, 2011, at 8:57 AM, Ashish wrote:If you do have access to MATLAB: http://www.mathworks.com/Create a schema for the file (i.e specify the format you want, the dimensions, variables and attributes) using ncwriteschema.You can reuse this schema in case you want to create multiple files: http://www.mathworks.com/help/techdoc/ref/ncwriteschema.html Read the data in using textscan.

Many such packages can create netcdf files. It might be easiest to read your files into a package you are familiar with, then write the netcdf file in the package.Regards, --DaveOn Sat, Jul 30, 2011 at 4:34 PM, spazm <kaan@xxxxxxxxxxxx> wrote:Hello,I have been googleing to find a solution to convert a couple hundreds of ASCII files to Netcdf however, the solutions I found don't really fit intomy data set.
