Hi Mohamed,

 

You can use two compare components (smaller than and larger than) and then a Boolean AND gate to combine the results. This should give you a list of True/False values which you can then use to cull your data. Use the Cull Pattern component for this.

 

You can also use an expression component to unify the first three steps, the following expression will achieve the same:

 

(x >= 30) And (x <=150)

 

The resulting list of True/False values must again be processed by a Cull Pattern component.

Thanks David. But how can I feed the "P" in the Cull Pattern Component making it extract only the "True" values?

Thanks. I figured out a way to do it.

can we not use masking in the branch compare component? One problem I have using maskign is that real numbers seem to give an exception when used in a mask string i.e.

 

[0-10] will select points with x in the range 0 >= x >=10

but [0-10.5] will cause an exception.

 

Can we get some help for the syntax for masking?
