Error when trying to plot spectrograms #112
Comments

@skraftarcher See Marie's comment on issue #111 It seems like you are having a similar issue. Do you have the Signal Processing Toolbox? You can check by typing |

Thank you. Simple solution to that problem. I was able to build an LTSA and work with the interactive detector to fine tune my settings. But when I try and run the batch detector I get the following error.
|
|
Hmmm that seems like a more complicated error than just a missing function/toolbox and may require some debugging. I've never worked with the ship detector remora, but it seems like maybe a data input issue. |

The same LTSA works with the Soundtrap 48kHz batch detector settings that are included as an example. However, when I adjust the settings to actually detect the known boats in the recording I get the error above. |

Hi, what is the bandwidth of the LTSA you are using, and what are the
frequency bounds you're using?
It looks like the frequencies specified under these settings may not be
represented in this LTSA.

I am not in front of my computer at the moment - but the same LTSA was used to fine tune the settings in the interactive detector as was used in the batch detector when I got the error I took the screen shot of. The interactive detector worked and the batch detector did not. |

The frequency bounds are most definitely within the bandwidth of the LTSA- soundtrap recorded at 48kHz and the LTSA made with 5s averages and 48Hz bins. I have tried many different frequency bounds and get the same error but the maximum high band frequency has not been higher than 5000 Hz. The only thing I can think of is that I am working in a shallow estuary and boat passages are quite short (between 10s - 1 minute). I have had to change the close and distant thresholds to 10 and 20 seconds respectively. Perhaps that has caused some sort of issue? |

Ok, thanks for checking. You might reach out to the original developer
(Alba Solsona Berga, ***@***.***) for help.
I'm guessing a screenshot of the parameters that worked, and the parameters
that don't work would be helpful.
Also letting her know if it's running and then crashes, or just crashes
immediately. If you're able to run Matlab in debug mode (type dbstop if
error in the command line, then try to run the code) it would be helpful to
know what the values of these variables involved are when it crashes:
lowB1, hiB1 and the size of pwr.
Best,
Kait

Thank you - I will contact them. One thing I did just figure out, in my trouble shooting to see which settings were causing the issues - if I fine tune the settings in the interactive detector then save them and try to load them in the batch detector it will not run. But if I change the settings to the exact same settings in the batch detector window (without loading the settings I saved in the interactive detector) it does run. I am very much not a matlab person so I am less helpful than normal in the troubleshooting here. Thank you! |
I recently downloaded Triton (11/25/2024). Whenever I try to plot a spectrogram (LTSA or from a single wav file) I get errors. The following is a screenshot of the errors I get when trying to plot a spectrogram of a single wav file:
