Filtering a channel based on the values of another channel

[Andrea12345]

Hi all,

I have imported in DIAdem some height measurements I have taken with a laser profilometer. Each profile consists of 3 channels: X (position), Z (height) and I (laser intensity). I would like to discard (set to novalue) the Z value for those readings whose laser intensity is less than 100. Is there a quick way of doing this?

Thank you.

Regards

Andrea

Call Calculate("Ch(""filtered/Z"") = Ch(""unfiltered/Z"")*(1+CTNV(Ch(""unfiltered/l"")<100))")
