Sphinx train latest update vtln error

[rayava]

Did any oe tried for the vtln training using sphinx train recently
developed.There is some issue while extracting features with warp factor

the error is it is not able to create mfc files with warp facor like 0.80.mfc
0.85.mfc and so on

This is a bug which we need to fix soon. Your help on that is welcome. The
feature extraction should be moved to 000.comp_feat stage.

The solution for the problem is

Log("Phase 5: Extracting features with warp factor $warp\n");
if ($have_feats) {
Log("Phase 5: Skipped, feature files already exist\n");
}
elsif (-x "$ST::CFG_SCRIPT_DIR/make_feats.pl") {
my $logfile = "$logdir/${ST::CFG_EXPTNAME}.extract.$warp.log";
my $rv = RunTool('../scripts/make_feats.pl',
$logfile, 0,
-c => $ST::CFG_LISTOFFILES,
-eo => "$warp.$ST::CFG_FEATFILE_EXTENSION",
-ei => $ST::CFG_WAVFILE_EXTENSION,
-di => $ST::CFG_WAVFILES_DIR,
-do => $ST::CFG_FEATFILES_DIR,
-mswav => $ST::CFG_VTLN,

-cfg => $ST::CFG_FILE,
-warp_params => $warp);
if ($rv != 0) {
Log("Failed in warp $warp");
exit 1;
}
}
else {
Log("Failed to find a script for feature extraction");
exit 1;
}

just remove the whole code between

Extract features (unless they're already there)

Wait for them all to finish, and collect their likelihoods

and paste the above code in between those

the vtln problem is solved

the 12.vtln_align log:
