[yam]Metadata

[Blaž Vičič]

Hello again.
Another day, another problem.

I am trying to process few years of data for a set of stations. I already
removed the instrumental response and downsampled the data. The error I get
is this one:

(obspy) pb-vicic:proc_2 bvicic$ yam correlate 1

The above exception was the direct cause of the following exception:

line 735, in next

    raise value

Exception: No matching channel metadata found.

In the first run I did, the error happened somewhere at the beginning
(iteration 200/3000+) so I checked if maybe my miniseeds have wrong
sta/chan inside. But they are all what they should be. I even forced the
tr.stats.station/chan to be exactly what I wanted. But the error happened
again. So I removed the first year of data, but now the error happened
again somewhere later in the dataset. Any idea what could be wrong or how
to go past this? It would be useful if I would know in which miniseeds to
look for the problem.

Cheers
Blaz
