What is in final.occs

[Ondra K]

Hi,
I'm curious what's inside final.occs and why does steps/align_si.sh need it. I'm not seeing any immediate usage after the copy...

 58 cp $srcdir/cmvn_opts $dir 2>/dev/null # cmn/cmvn option.
 59 
 60 [[ -d $sdata && $data/feats.scp -ot $sdata ]] || split_data.sh $data $nj || exit 1;
 61 
 62 cp $srcdir/{tree,final.mdl} $dir || exit 1;
 63 cp $srcdir/final.occs $dir;
 64 
 65 
 66 
 67 if [ -f $srcdir/final.mat ]; then feat_type=lda; else feat_type=delta; fi
 68 echo "$0: feature type is $feat_type"

It's the per-transition-id occupation counts. They are rarely needed
-- e.g. I think they might be used somewhere in the basis-fMLLR
scripts.
