Hi Waylon, As a follow-up to my previous email (which wasn't sent to the whole group), here is a solution that will work using nc_eqn in the ARM NetCDF Tool Suite: nc_eqn -i F.nc "[X]=[X]*([X]!=32) + 45*([X]==32)" It doesn't look exactly intuitive, but it will work. Let me know if you have any questions about this or any of the ANTS tools. Sherman Beus ________________________________ From: owner-netcdfgroup@xxxxxxxxxxxxxxxx on behalf of Waylon.Collins Sent: Fri 11/11/2005 6:32 AM To: netcdfgroup@xxxxxxxxxxxxxxxx Subject: Manipulating netCDF files Dear group members, After reviewed the Unidata list of software that manipulates netCDF files, I have yet to find one that can perform the following task -- I need command-line software (that can run in a Redhat Enterprise Linux environment) that will allow me to replace data values, associated with a particular variable, with values that I can specify. It needs to allow for a logical operation. For example, the software needs to be able to perform the following -- "Any datum of variable X, within netCDF file with filename F.nc, that equals 32, change it to the value 45. Thus, the original file F.nc is now altered, or the altered file is now named G.nc". Any help will be greatly appreciated. Sincerely, Waylon -- ********************************************************************** * Waylon G.
