Garima,
We need to see more of the compiler log to see what your error might be.
After compiling CNS with make install and then source cns_solve_env after entering into C-shell tcsh
I was trying to run cns after typing cns

Hello everyone,
I also got these errors and was able to resolve them.
Just take care of installation steps of CNS:
-> After registration, download xyz.tar.gz file âxyz = cns_solve downloaded versionâ
-> Enter the command in terminal: gunzip xyz.tar.gz
-> Then enter: tar xvf xyz.tar
-> This will create a new cns_solve directory. Now enter into this directory and copy the path.
-> Now open the file cns_solve_env and paste the copied path in place of âlocation of CNSsolve directoryâ
-> Then open the terminal in this directory, and enter the command:tcsh
-> Then you entered into C-shell, now enter the command: source cns_solve_env
->Then enter: cns
-> Your software will definitely run without any error.
Dear Dr. Bonvin,
I am having the same problem with CNS installation, but I cannot figure out how should I remove -fast-math flag. In my Makefile I donât have such flag. I tried to run make no-fastm after make clean but it looks like compilation still runs with fortran -ffast-math option.
Thank you
Depending on your operating system, when installing CNS a directory specific for your OS will be created, e.g. intel-x86_64bit-linux/source on a Linux 64bits system.
Go into that directory and edit the Makefile script.
Then in that dir try: make cns_solve
Thank you very much! I think itâs fine now
Hello,
I did exactly those steps and when I entered cns there was the error: cns: Command not found.
any idea what did i do wrong?
In order to use cns you must first source the cns_solve_env from the installation directory (provided you edited it properly. And check that the compilation was successful
Dear all,
I have tried making all the modifications that have been suggested so far in the forum. I am still getting the following error -
%SETFPEPS Machine epsilon determined to be 0.494-323
%SETFPEPS error encountered: Machine epsilon value is too small
(CNS is in mode: SET ABORT=NORMal END)
WARNING: program encountered a fatal error.
However, in interactive mode, program execution
will continue. Proceed at your own risk.

I am using 64 bit Ubuntu 18.04.3 LTS. Kindly advise if I can try any other value of MXFPEPS2. I tried 8192 and it gave the same error.
Thanks in advance.
P.S. replacing the entire SETFPEPS subrouting from bosmith produced a fatal error.
I recently recompiled CNS on OSX and CentOS7 using gfortran.
The compiler flags are:
F77 = gfortran
F77STD = -fdefault-integer-8 -w
F77OPT = -O3 $(CNS_MALIGN_I86) -funroll-loops -ffast-math -static
F77FLAGS = $(F77STD) $(F77OPT) $(EXT_F77FLAGS) $(F77BUG)

CC = gcc
CPP = g++
CCFLAGS = -O -DINTEGER='long int' -DCNS_ARCH_TYPE_$(CNS_ARCH_TYPE) $(EXT_CCFLAGS)

LDFLAGS = -w $(EXT_LDFLAGS)

Dear Dr. Bonvin,
Thank you very much for your prompt reply. âcnsâ seems to be working now.
Thanks again.
Hello,
I am trying to perform a HADDOCK docking run locally for the first time, however when I enter haddock2.4 in my run1 directory it comes up with an error message saying ./protocols/cns1 not found. I have installed cns_solve_1.3 and set CNSTMP on the haddock configuration file to the cns executable directory (/home/user/software/cns_solve_1.3/intel-x86_64bit-linux). I also edited the run.cns file to queue_1=âcshâ and set cns_exe_1="/home/user/software/cns_solve_1.3/intel-x86_64bit-linux". Has anyone got any idea what I might be doing wrong?
The cns_exe must be the link to the executable and not the directory where it resides.
If you have the correct link you should be able to simply give it as command and see CNS starting.
Thank you for your prompt reply! I managed to link cns_exe to the correct executable now (software/cns_solve_1.3/intel-x86_64bit-linux/bin/cns) however when I now go to proceed with the docking run I get an error stating there is a problem with my CNS executable. Any idea what the problem is here? How could I check CNS has been compiled properly? As also when I go to source cns_solve_env now I also get an error saying that there is unexpected syntax in line 32 : if ( ! $?CNS_ARCH ) setenv CNS_ARCH$CNS_SOLVE/bin/getarch`. Any help would be greatly appreciated!
Did you try a fresh run and not the old one giving problems?
Yeah I attempted a fresh run removing the run1 directory that was created in my previous docking attempt. Still get the error message saying there is a problem with the CNS executable defined in run.cns.
can you manually start CNS based on the definition you put in run.cns?
I.e. copy and paste in the command line
when I attempt to do that I get the following error message:
%SETFPEPS increase value of MXFPEPS2 and recompile
%SETFPEPS error encountered: Could not determine machine epsilon
(CNS is in mode: SET ABORT=NORMal END)
Did you compile it with the provided routines from haddock? In the cns1.3 dir
The forum also already has answers to that problem - search with one one the error keyword
Dear All,
I have installed local version of HADDOCK2.4 (September 2020 release) on Centos7.7.
I tried to run water refinement (refine-complex) with my own protein and then with the example protein (all residues have their unique residue numbers in both A and B chains) and was getting an error message:
waiting for /../run1/begin/e2a-hpr_1GGR_B.pdb...
waiting for /../run1/begin/e2a-hpr_1GGR_B.psf...
Error in the topology generation: prot_psf_mol1 could not be created
=> HADDOCK stopped
in the /âŚ/run1/begin/generate_1.out file is the following message:
RTFRDR>set message=off echo=off end
%RTFRDR error encountered: exceeded MXRTRS (RTF) parameter --> recompile program
(CNS is in mode: SET ABORT=NORMal END)
I changed in software/cns_solve_1.3/intel-x86_64bit-linux/source/rtf.inc MXRTRS from 200 to 4000
RAMETER (MXRTRS=4000,NICM=50)
and also other lines as described by @srinivas_penumutchu as well as Makefile and machine.f looks like described by @amjjbonvin on 29.10.2019 but I am still getting the same error.
I would appreciate your help very much.
