Hi,

It will be harmful, since the feature extraction stops when the error raises. This means that you have incomplete features (and later cmp) files.

You might then get not enough or no data for some units.

It means that determinant of Toeplitz+Hankel matrix, which is a coefficient matrix of a linear system in MGC analysis, is too small (< 1.0e-6).
You can modify this threshold via -f option as a smaller threshold

Does anyone know the reason for this warning and Is it harmful to the model training?

Thanks!
