Error running 1 of 2 channels for Step 3

[edelaserna]

Hi! I am trying to generate the surface mesh for one channel of my image stack. I have loaded both channel stacks as separate channels in a movie. When I start at Step 3 and only select 1 of the 2 channels, I get the following error report:

--Step 3: Mesh

Intermediate brace '{}' indexing produced a comma-separated list with 0 values, but it must produce a single value when followed by subsequent indexing operations.   

I do not have this issue when I run Step 3 with a movie containing only 1 channel. I am making sure to check "use deconvolved", so that does not seem to be the issue. Is there a step to handling multi-channel movies that I might be missing that would generate this indexing error? Thanks!
