format error in lattice file...

[Partha Lal]

Hello,

I'm trying to get a lattice error rate from an htk format lattice file but
keep getting a format error:

> lattice-tool -read-htk -in-lattice
results/globalphone-sp/lattices/mfcc13+dd/hmm4_2_512/SP002_21.lat
-out-lattice
results/globalphone-sp/lattices/mfcc13+dd/hmm4_2_512/SP002_21.pfsg
> nbest-lattice -read
results/globalphone-sp/lattices/mfcc13+dd/hmm4_2_512/SP002_21.pfsg
-lattice-error -reference `cat
data/globalphone-sp/wrdfile/rmn/SP002/SP002_21.wrd`
results/globalphone-sp/lattices/mfcc13+dd/hmm4_2_512/SP002_21.pfsg: line 2:
unknown keyword
format error in lattice file

I can't see what's wrong with my lattice files - I've made them available at
http://homepages.inf.ed.ac.uk/s0565860/lattice_problem/ .
Can anyone suggest what might be wrong?

Thanks,

Partha
