Dear PhysIO Experts,

Attaching a figure with some thresholds applied to Y Grad. The Volume Peak is negative, and using a threshold like YGrad(YGrad>-1000 & YGrad<500) = 0; I got a figure like that, great (attached). Notice that even if I apply the abs, the volume marker has lower amplitude. And it is impossible to set the PhysIO Batch defining the volume peak with negative value.

Any idea?

Thanks again!
