Hi Rob,
I can read those files. I'm a little concerned by the fact the station
name in the filename is not the station name in the actual data
contained in the file. That is strange, and this could be a problem.
Indeed, the station table is populated from the filenames, and the
archive is scanned searching for selected stations in the configuration.
But, the scan reads data within the file and stores metadata in the
database, and these metadata have different station names.
Do you have an idea why the names don't match ?
Thomas
