Hello! I'm trying to build regression-class trees with the AR-HMM demo, but I'm getting the error:

ERROR [+9999] CalcClusterDistribution: not available for autoregressive HMM

Looking into the code of the HTK patch, I see the lines where this statement came out:

@@ -7272,6 +7601,8 @@ void CalcClusterDistribution (RNode n)
if (acc != NULL) {
/ check pure stream and vecSize */
if (n->pureVecSize && n->pureStream) {

•        if (acc->sqrAr != NULL)
  

•           HError(9999, "CalcClusterDistribution: not available for autoregressive HMM");
       for (k=1; k<=n->vSize; k++) {
       sum[k] += acc->sum[k];
       sqr[k] += acc->sqr[k];
  

Would you mind to explain what the comparison "if (acc->sqrAr != NULL)" is doing and why this error happens?
Thanks, and best regards,
Marvin C.

Is there a script file which can extract mgc/lf0/bap files from wav file?
I can not find it in the scripts directory.

I can see the configure.ac file on the project, but I think it also needs the configure file to run the demo.
