MuSiCal looses signatures when refitting against reduced set of signatures

[quail768]

Hey @Hu-JIN!
Cool tool! I'm trying to apply it to some WGS data.
When I do the refitting against the entire 96-signature catalog, I see the signatures I'm looking for. However, when I reduce the catalog to the signatures I'm expecting(10 signatures), the signatures that appeared when refitting against the whole signature catalog do not appear anymore even though they are part of the reduced catalog. Any thoughts on why this could be happening?
