Thanks Wayne, that works great for regular stacks.
I'd also like to open the hyperstacks as virtual stacks. I see
FileInfoVirtualStack is used for virtual stacks, and looking at the source I
feel like the following should work, but it doesn't.
StringBuffer sb = new StringBuffer(100);
sb.append("images=" + fi.nImages + "\n");
sb.append("channels=" + channels + "\n");
sb.append("frames=" + frames + "\n");
sb.append("hyperstack=true\n");
sb.append("mode=grayscale\n");
sb.append((char)0);
fi.description = new String(sb);
new FileInfoVirtualStack(fi);
This opens my file as a virtual stack, but not as a virtual hyperstack. Am I
missing something?
Thanks,
-Josh
