A few things spring to mind that might be simple fixes, since the syntax looks right:
1.) I recall some parameters in NAMD being case-sensitive. In the manual, its extraBonds and extraBondsFile.
2.) Make sure the res.txt is in the right place. Should be in the same directory as the .conf/.namd file.

I would like to use the torsional restraint in the simulation. I went through the manual. This is my first time of adding restraints

the file contents are below

but after minimization the run is not going with saying an error
Reason: FATAL ERROR: Setting parameter extrabonds from script failed!
Fatal error on PE 2> FATAL ERROR: Setting parameter extrabonds from script failed!
Could someone let me know what the error is where I am doing a mistake, I have also a question regarding the k spring constant value, how to specify 1.0 or 2.0
