title: Error with run.sh in kaldi tidigits example, what am I doing wrong?
body: <p>I'm just setting up Kaldi for the first time and going through the tidigits example. However with run.sh, I get:</p>
  
  <pre><code>steps/make_mfcc.sh --cmd run.pl --mem 2G --nj 20 data/test exp/make_mfcc/test mfcc
  
  utils/validate_data_dir.sh: Successfully validated data-directory data/test
  
  steps/make_mfcc.sh: [info]: no segments file exists: assuming wav.scp indexed by utterance.
  
  run.pl: 20 / 20 failed, log is in exp/make_mfcc/test/make_mfcc_test.*.log
  </code></pre>
  
  <p>Looking at the log files, I see the issue is:</p>
  
  <pre><code>bash: line 1: compute-mfcc-feats: command not found
  
  bash: line 1: copy-feats: command not found
  </code></pre>
  
  <p>This seems to be a PATH issue, and looking at other forums online seems to confirm this. However I'm not sure how to resolve the PATH issue. I've traced that compute-mfcc-feats and copy-feats commands are called in make_mfcc.sh in the steps folder (supposedly a symlink to the wsj example). Please help!</p>
