Error in UIControl Callback

[lhobson13]

I get the following error when processing my file, and I'm not sure why. My .wav files should all be the same but I get this error on a couple of them when I try to process the file.

The logical indices in position 2 contain a true value outside of the array bounds.

Error in syllable_activity_file_stats (line 72)
syllable_data=syllable_data(:,syllable_use==1);

Error in compute_musv (line 93)
[syllable_data, syllable_stats, filestats] = syllable_activity_file_stats(handles, audiofile,
TotNbFrames, syllable_data);

Error in process_file (line 7)
[syllable_data, syllable_stats, filestats,
fs]=compute_musv(wav_dir,wav_items(selected_wav),handles);

Error in processAudioFile_Callback (line 2)
handles=process_file(handles);

Error in
matlab.graphics.internal.figfile.FigFile/read>@(hObject,eventdata)processAudioFile_Callback(hObject,eventdata,guidata(hObject))
Error while evaluating UIControl Callback.

Can you share a wav file for us to reproduce and debug this issue?

Hi, we are also experiencing this issue. Here are the files. Thanks!

I have fixed this problem.
FIX:
Find the following lines in the file "syllable_activity_file_stats.m" :
if isempty(syllable_use)
syllable_use=ones(1,length(syllable_data));
end
and replace them with the following
if isempty(syllable_use)
syllable_use=ones(1,size(syllable_data,2));
end
Save the new version of the code and rerun.

Explaination:
The problem is that the cell array "syllable_data" has 9 rows and a number of columns equal to the number of detected calls in the file. The errors you pasted above come from the lines in "syllable_activity_file_stats.m" where the variable "syllable_use" is defined. Those lines are:
if isempty(syllable_use)
syllable_use=ones(1,length(syllable_data));
end
If the number of syllables is less than 9, the length function will return the number 9 (it returns the max of the size of the array) and not the number of columns. Then, when it is used in the line
syllable_data=syllable_data(:,syllable_use==1);
it will try to access 9 columns when there are only less than that and it will throw and error.

For example, say a file has 8 calls. Then the size of "syllable_data" will be (9,8), i.e., 9 rows and 8 columns (one for each syllable). Then length(syllable_data) will return 9 instead of 8. Then when the line syllable_data=syllable_data(:,syllable_use==1); is executed, it will throw an error since it is trying to access 9 columns of the data when there are only 8.
