HIC curve does not take trimmed curve

Hi all, 

Sorry if this questions is already made. I could not find it when I check prior posting this.

My issue is that I got a Head acceleration curve that comes with a peak between 0-1ms that I want to trim, otherwise it would drive the HIC curve calculations.

I get the accel curve, trim it so it shows that is trimmed without that initial portion. 

When I request the HIC curve I have to point to the trimmed curve (in this case, 'w2p1c2') but the curve refers to the trimmed portion of the curve. 

What I am missing? I am not doing the trim properly (the curve 'w2p1c2' comes with a function 'fx,id=1, and it appears trimmed in the graph)? Should I add some additional parameter to the HIC function (I tried to point to 'w2p1c2f1' but ofc it makes no sense)?

Thank you. 

PS: In the attachment one can see the original Head Acc curve (dark blue), the trimmed one (green) and the HIC curve (dark green) that surrounds the trimmed data besides it used the green curve as input.
