Error computing Soundscape Metrics

[laralps]

Hello to all!

My data was collect with SoundTraps as wav files of 96kHz sampling rate and 10-minutes length.
I'm testing computing soundscape metrics in triton for the first time and I don't have much experience with matlab, so I started generating soundscape LTSAs with default settings (1s, 1Hz and 7 days resolution). LTSAs were generated correctly, but when I try to compute soundscape metrics (300s bin size for time, 1hz bin size for frequency, 50% min. seconds/average and single value calibration), I get the following error message:

Unrecognized function or variable 'utFindFiles'.

Error in sm_cmpt_metrics (line 15)
    utFindFiles('*.ltsa', REMORA.sm.cmpt.indir, 0);

Error in sm_cmpt_control (line 136)
    sm_cmpt_metrics;
 
Error while evaluating DestroyedObject Callback.

What can be happening, is it not recognizing the soundscape LTSA files?

Any help is much appreciated!
