No, you have to say to namd the following:
So, you have to change X by B. "X" is just the name of the protein, not
a big deal. (B is the column where you specify which atoms will be held
fixed during the simulation)

Thank you very much for the answer.
The character "X" is added as the fifth item in the line
which is seemd to contain the fixed atom. (Is it right?)
ATOM 1 C ALA X 3 -1.152 1.490 -3.770 1.00 0.00
ATOM 2 OT1 ALA X 3 -1.019 0.921 -2.959 1.00 0.00
ATOM 3 OT2 ALA X 3 -1.855 1.795 -4.412 1.00 0.00
Is the description about the fixed atoms in the configure file
for NAMD program followings?
(The file name with the character "X" is "solv_fix.pdb"
under the directory "ala/output/".)
