Error on Acoustic model training, SYSTEM_ERROR: No such file or directory

[Shimul]

Operating System : Ubuntu 11.10
Using Software : sphinxbase-0.7 , sphinxtrain-1.0.7 , pocketsphinx-0.7

after creating the task in my project folder sbs_asr by this command

../sphinxtrain/scripts_pl/setup_SphinxTrain.pl -task sbs_asr

i got the folder structre that are required for training. after that when i execute the command

perl scripts_pl/make_feats.pl -ctl etc/sbs_asr_train.fileids

for feature files making than i got an error

INFO: sphinx_fe.c(862): Converting /root/tutorial/sbs_asr/wav/sbs_asr_train/sanjoy/011.wav to /root/tutorial/sbs_asr/feat/sbs_asr_train/sanjoy/011.mfc
SYSTEM_ERROR: "sphinx_fe.c", line 276: Failed to open /root/tutorial/sbs_asr/wav/sbs_asr_train/sanjoy/011.wav; No such file or directory

In this error it says it cant find my wav file but the wav folder contains the file and i can see that it understand my folder stucture too and its correct but why its not finding the wave file i can't understand.

Please help me to get rid of this error and making the feature files to train the acoustic model.I am badly need this because i am doing my final year project on this topic.

you can see my etc folder all files,screen-shot of my folders structure and check out the 011.wav file by downloading from this link

Ok the real answer is that in your fileids file there is an invisible UTF-8 BOM character: 0xef 0xbb 0xbf

Sphinxtrain doesn't know how to hangle this character. Remove this special character from the fileids file in order to run the training.

For the future use an editor which doesn't insert this character.

Thank you very much Sir.I got my mfc files.
