Do you mean that the lower F0 limit affect the number of generated F0 frames?
When I changed the lower F0 limit, the number of generated F0 frames
were not changed.

It's strange.
Please, let me know the number of samples of your raw file, command
lines of mgc analysis, and the number of generated mgc frames,
respectively.
