Dear Dr. Spoel,
Thank you for your reply. Do you mean calculating fluctuation properties for different pieces of the energy file and calculating std deviation? I tried that but the std deviation changes depending on the length of the blocks that I use.

You will have to do it manually for now by cutting your energy file in
pieces (well, use the -b and -e options).
