I have scanned a database of three stations. One of those stations has two instrument types, HN* and HH*. I wanted to try and use both the seismometer data and the accelerometer data. In my station table I have that station twice, once with the instrument type "HN*" and again with the instrument type "HH*" When calculating the CC, I get an error related to to this section of api.py (1430-1441); if len(st) == 2: mask = np.logical_or(st[0].data.mask, st[1].data.mask) elif len(st) == 3: mask = np.logical_or(st[0].data.mask, st[1].data.mask, st[2].data.mask) # apply the mask to all traces for tr in st: tr.data.mask = mask # remove the masks from the stream st = st.split() return st The error is because st = 4, (HHN, HHE, HNN, HNE). To try and work around, it seems like I can not just tell it in the station conf to not use the HN* station - it still tries to and fails. (1) am I doing something wrong here in general (2) how do I reset the scan archive if I remove this instrument, or do I just have to delete the database and start over?? -thanks -- Ashton F.
