"Cant use $ in this way in a function"

Share icon

What am I doing wrong here? 

make W_sigma
make datawaveCropped 
string bloach = "W_sigma"
datawaveCropped=$bloach
Try this:
make W_sigma
make datawaveCropped 
string bloach = "W_sigma"
wave wbloach=$bloach
datawaveCropped=wbloach

Hope this helps,
Kurt

That's right. Or when looking up a pre-existing wave at a time when it will exist.

To be more precise, though, you can use Wave/Z where the /Z means "look up a wave but it's OK for it to not exist". Then use WaveExists() function to find out if the wave reference variable actually refers to a wave.
