Hello,
There was a very handy $N expression that selected the last point of a curve when put in a group sop.
I tried @numpt - 1 in an GroupExpression sop without success. How can I this in h16 ?
Many thanx.

That is weird, it is like the Pattern field no longer exists in the Group node. Why change something that worked just fine..?
You can drop down a Delete and your expression works in the Pattern field. Just activate Delete-Non-Selected and you will get your single end point.

Because I believe they wanted to lower the barrier of proceduralism in Houdini for new comers.
One should be able to select the 1st/last member of a list without having to learn HScript/Vex beforehand.
So, they introduced the Group by Range node, set the Method to ‘Relative to Start/End’, check the ‘Invert Range’ checkbox and then increase the Start/End value sliders to your liking.
Now this style of Grouping is more accessible to a wider range of Houdini users.
I like this direction of bringing Houdini out of the TD spectrum and into the range of the average Generalist.

They both do the same thing when placed in a groupexpression sop, I just want to make sure there is a reason for one or the other.
@ptnum == @numpt-1
@ptnum == `npoints(0)-1`
if you want something that selects last point on all input curves instead of just last point of the input geo, you can do this
vertexprimindex(0, @vtxnum) == primvertexcount(0, @primnum) - 1
