SEPIA's QSM application has two options to compute a weighting map for QSM dipole inversion methods that incorporating prior information:
User can specify a weighting map, or
User can specify a magnitude data for signal weighting.
In v0.8.0, when option 2 is chosen, there is a bug in the code such that the subsequent signal weighting map is automatically set to the binary signal mask, instead of using, e.g. the RMS of the (multi-echo) magnitude data.

This bug will be fixed in the next update.
