One trick that may work for you is to rewrite that selection statement
more compactly, plus using "resid" instead of "residue".
E.g.
(segid A and (resid 169 or resid 175 or resid 172 or resid 37 or resid
222 or resid 126 or resid 51 or ..... ) )
Failing that, the parameter
PARAMETER (STRING_SIZE=264)
in the file "cns.inc" would appear to be responsible. Redimension and
recompile. 264 seems rather small.
Even though strings are inconsistent between C and C++, at least both of
them have fairly straightforward dynamic memory allocation, and this
error is one of the types of "joys" of more classical Fortran versions.

Dear all,
My model (total 354 residues) has 13 residues which have alternate
conformations. when I generate the alternate conformation with
alternate.inp in CNS, the program does not give me the AC conformers
because the atom selection only allows for 265 letter. However, all
these residue selection will more than 264 strings. Does any one know
how to the alternates in CNS?
