Measuring a stack without opening it?

[MaxPeters]

Perhaps I'm just stupid or blind but neither found this function in the help file nor with google.....

I have a stack of about 600 TIFF files merged in one file.
The first and the last image are stored in two separate files.
I want to set the ROIs in the last file and then measure the whole stack without the need to open it (takes awfully long).

Is there any way to do it?

Thanks,
Max Peters

Sound like you need to open as a virtual stack.  Try "File->Import-
 >Tiff Virtual Stack..."

It will still take a while to do the measurement, as all the data will  
still have to be read off the disk, but it will save you memory and  
you won't have to load the entire stack before you start.

Thanks for the tip!
I didn't know the function before.
Initially when I tried to use "multi measure" as before I got the following error message:
"Custom code is required to process this virtual stack (e.g., "Process Virtual Stack" macro) or it must be converted to a normal stack using Image>Duplicate, which will require 1151MB of additional memory."
After downloading the plugin "Time Series Analyzer" everything worked.
