hi all.. here is an interesting question.. i have a set of text files that represent certain images, but so i can work with the images more freely i was wondering if there was a way or many different ways of converting these text files to netcdf?? thanks a bunch! chad -----Original Message----- [mailto:owner-netcdfgroup@xxxxxxxxxxxxxxxx]On Behalf Of martin.schultz@xxxxxxx Sent: Wednesday, October 08, 2003 3:23 AM Hi Mark, usually ncks -A file file2 will do.
