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,
New files are on the way to you. I changed conversion algorithm from
'ref2mseed' to 'rt2ms' (also from PASSCAL, but more modern). rt2ms
produces much the same naming scheme except it has a YYYY format instead
of a YY, among other changes.
Hope this helps,
Rob

http://mailman-as.oma.be/mailman/listinfo/msnoise Thanks, Thomas. I am on travel right now, so I
will have to get you
the parameters Monday. There is a finite chance I screwed up and gave
you SEG-Y files, they are named similarly. If that is the case, I
apologize for the confusion.
I tried reading SEG-Y but it doesn't work
either. Let's wait till Monday
to check !
Cheers

Hi Rob,
OK, got your files. I can modify the code to automatically find the
stations, that's OK.
But, I can't read them in Python. Although you state it's MiniSeed
(and I believe you :-) ), I can't find the proper parameters to read
them. Did you pass any argument to the converter ? Are you able to
open them using another tool ?
Cheers,
Thomas
