Hi Wolfgang,
'Virtual Stack' means that the data are not in memory but each slice
(frame) is read from a file (the AVI file in your case) if it is needed.
The file is read-only, so you cannot modify any data or add a slice.
https://imagej.nih.gov/ij/docs/guide/146-8.html#sub:Virtual-StacksYou can delete slices from virtual stacks, however (ImageJ has a table
where the slices of a virtual stack can be found in a file; deleting a
slice simply deletes the corresponding entry in that table).
Michael
