Cannot run a trial experiment

Created by: sun8608

Hello! I was just trying to run a trial experiment using Voxforge database following the instruction of manuals: sudo /usr/local/bin/verify.py -vv -d voxforge -p energy-2gauss -e mfcc-60 -a gmm-voxforge -s ubm_gmm --groups {dev,eval}

but I kept getting the error message:
bob.bio.base@2015-08-01 11:03:15,971 -- INFO: - Preprocessing: processing 6561 data files from directory '[YOUR_VOXFORGE_WAV_DIRECTORY]' to directory 'temp/ubm_gmm/preprocessed' bob.bio.base@2015-08-01 11:03:15,975 -- ERROR: During the execution, an exception was raised: [Errno 2] No such file or directory: '[YOUR_VOXFORGE_WAV_DIRECTORY]/ColinBeckingham-20091029-hfv/wav/a0001.wav' Traceback (most recent call last): File "/usr/local/bin/verify.py", line 9, in load_entry_point('bob.bio.base==2.0.1', 'console_scripts', 'verify.py')() File "build/bdist.linux-x86_64/egg/bob/bio/base/script/verify.py", line 435, in main

I do not know where I can change the config file, I cannot find a folder with name 'config', there is one 'config' folder in under bob spear installation directory, but changing configuration of this one did not solve my problem; also the directory--build/bdist.linux-x86_64/ is actually empty, I do not know how the messages are retrieved.
