Hi,
    
        I am new to HTK and face the following problem,
I am using HTK for simple phone recognition in continuous speech, where I define each phone as a word.
I am using a set of dicrete features and discrete hmm's. My main problem is with using HInit or HRest to train phone spwecific hmm's
I get a strangfe bug when I try to initialize a phone HMM with HInit, it displays all the info and does absolutely nothing. doesnt even show whether observation sequences ar loaded.
With the same setup , if I use HInit for initialization without specifying any phone, it does correctly and loads all observation sequences and processes them.
1. Without phone specific : display ( i did not specify any phone in this command.
Hinit.exe -A -C config_D2.txt -M hmmx -H hmm1/hmmdefs -I D64_16.mlf -S train_sym.scp -T 1 -w 0.001 protod64E

processing happens and resukts are out successfully.
2. But when I specify a phone and an mlf (with time alignments)
Hinit.exe -A -C config_D2.txt -M hmmx -l aa -H hmm1/hmmdefs -I D64_16.mlf -S train_sym.scp -T 1 -w 0.001 protod64E

No further processing,  does absolutely nothing other than this, no observation sequences loaded.
I have thoroughly checked mlf file and it has all phones with time alignments.

I have checked the proto file and other files and they all seem to be correct, if I purposefully change anything in them it shows an error, but when everything is right, it does absolutely nothing. Request your help solving this issue/bug.
Thanks and regards
