Thanks Fred,

however, the issue is with the GUI-operation, not with plugins or macros (the latter was for demonstration only).

The person who originally contacted me, encountered the described problem when using the GUI and I think GUI-operations should work correctly.

The relevant ImageJ source code is rather convoluted and would require much effort to even understand the idea, not to speak of a correction...

Greetings,

This may or may-not be related, but when changing a slice label using
imp.getStack(),setSliceLabel(string,int) the displayed slice label does
not change, even when using imp.repaintWindow(); albeit the documentation
implies but does not specifically state that repaitWindow would update the
label.

Dear experts,

in certain cases there seems to be a discrepancy between the
slice/channel sequence of a hyperstack and the slice/channel label naming.

Attached please find a stack "stack.tif" consisting of six slices that
stand for two z-positions and three colours. When opening as *virtual*
stack and applying "Stack to Hyperstack..." to this stack with setting

Order:  xyzct
Channels 3
Slices   2
Frames   1

the result is the attached hyperstack "hyperstack-V.tif".

Corresponding ImageJ-macro:
    path=File.openDialog("choose file \"stack.tif\"") ;
    run("TIFF Virtual Stack...","open="+path);
    run("Stack to Hyperstack...","channels=3 slices=2 frames=1");
    Stack.setDisplayMode("color");
    exit();

The resulting hyperstack shows the *correct sequence* of slices and
colours but the names of slice/channel *labels are discrepant* (see the
attached screen-shot "example-view").

The effect does *not* occur, if "Stack to Hyperstack..." is applied to
the real stack, i.e. not to the virtual stack.

Could someone please confirm and perhaps even remedy this strange
behaviour?

Regards

Herbie
