When I try to split channels, I get the following error:

Comment 1 Sam Lord 2015-03-01 16:37:34 CST 
Split channels works when I uncheck "Enable ImageJ2 data structures" in options.
Comment 2 Wayne Rasband 2015-03-01 17:38:46 CST 
I get an exception if I use Split Channels with "Enable ImageJ2 data structures" checked in Edit>Options>ImageJ2. The Split Channels command works as expected if this option is not checked.

Duplicate of #1010. Fixed and uploaded. Run Help > Update... to receive the fix.

Note that it is also recommended to disable the "Enable ImageJ2 data structures" option in Edit > Options > ImageJ2, since this feature is still buggy and causes performance problems.
