If I remember correctly, this is an bug with NAMD 2.7 on Windows. Can you
try using NAMD 2.6 instead for the tutorial?

Subject: tutorial-l: tutorial is not working

I'm a new user of NAMD.I'm trying to run the "user-defined-force" tutoorial.
But every
time while running the tclforces simulation the system is showing some error
messages
like:

TCL: can't read "masses(1)": no such element in array
FATAL ERROR: can't read "masses(1)": no such element in array
    while executing
"vecscale $masses($atom) $linaccel_namd"
    (procedure "calcforces" line 11)
    invoked from within
"calcforces"

Can you please suggest me why I'm facing this problem and how to solve it.
