Problematic selections

[gnunezmir]

Hello!

I'm trying to measure acoustic parameters for a batch of bat calls. A handful of them are being flagged as problematic and I am not sure what may be wrong with them. Any guidance would be greatly appreciated. I am attaching one of these problematic .wav files.

Thank you so much!

Hi

I was able to read the file in R:

warbleR::read_wave("~/Downloads/delete2/108_Echo.wav")
seewave::spectro(warbleR::read_wave("~/Downloads/delete2/108_Echo.wav"))

Can you elaborate on why is it problematic or what code are you running?

Hi Marcelo,

Thanks for the prompt response!

As I try to create the selection table (using selection_table), the function flags ~12 wav files out of >1,500 as "problematic." I identified them using check_sels. It doesn't really say anything about what is wrong with them, just that they are "not OK". In context, we can't think of what could be wrong with them either compared to the other 1,500. Hope you could shed some light as to what kind of file will be flagged by check_sels.

Thank you so much!

if you run:

cs <- check_sels(X)

the column cs$check.res has the info about what was wrong with each row

[maRce10]

And please note that check_sels() doesn't flag sound files, it flags selections (rows) in a selection data frame

[gnunezmir]

Awesome! It appears these files "exceed sound file length." Does that sound reasonable to you given the file I sent you? We can work with that if this is normal behavior for WarbleR and not a bug. Thanks for the help!

[maRce10]

it means that the selection end (or even start) is higher than the actual duration of the sound file. That doesn't make sense so there is something wrong in your data.

Ah, I interpreted that incorrectly. Ok, thank you.
