Dear all One of my colleagues gots the idea to have included into each netCDF file a checksum or a signature to indicate if the file gots changed by some kind o f damaging (a virus or some hardware failures). The reason why we need such a information is the files gots larger and larg er and you can't guarantee if a file which comes from a backup or from a file copy is the original one. We have had a very interesting hardware failure on a harddisk on one of our systems which inhibits the copying of a netCDF file in that way that's only one parameter of a file was not readable. It takes a long time to understan d why this file on an other machine was readed right. If there will be automaticly included a kind of self diagnostic it is much easier to find out why some data does not look as supposed. And you know immediatly that there is something wrong! I think if there are ideas how to implent this feature it should be done. I t is very important for all of us! cheers Reimar -- Forschungszentrum Juelich email: R.Bauer@xxxxxxxxxxxxx http://www.fz-juelich.de/icg/icg-i/ ========================= ========================= ================ a IDL library at ForschungsZentrum Juelich http://www.fz-juelich.de/icg/icg-i/idl_icglib/idl_lib_intro.html
