Title: Error in connectivity
Post by: shabnam naderlou on September 21, 2018, 05:46:20 PM
Dear All,
I am beginner to RASPA software. I am working on diffusion and storage of drugs within mofs.
At the starting kevel, I resieve an error and I dont solve it at all.
This is the error:
Error in CBMC growing scheme. No atoms  can be grown,  check the connectivity of your molecule
I checked all input files and those of them seems correct. How can I solve it?
Thanks for your time.
Best regards,

The most common reason is that your molecule contains a ring. RASPA can not handle flexible rings.

yes. I have a ring in my structure. but in molecule file, I define all of bonds as rigid. here is related molecule.def file.

Remove the empty line after "11 H_xyl    0.48371800   -2.55620700   -0.00016000"

thanks for your reply.
I corrected this, but at this time, after 1 hour, running finished without any output or other folders :-[ :-[
here is my trial running simulation.input file:

in all of my runnings, I did not see any output file!
also, I did not see any error!

For our version of the code, this should not happen (on a standard unix system) and indicates something very strange on your system. Use a debugger to found out why it fails.
If you're using a version by other people (for example the numat github version) then it could be that their python additions might cause this problem.

I tried to install your version with python setup.py install command. but when I run the program, I recieve this error:
OSError: /usr/local/lib/python2.7/dist-packages/RASPA2-2.0.3-py2.7-linux-x86_64.egg/RASPA2/simulations/lib/libraspa2.py: invalid ELF header

We do not have anything to do with python (that is an addition by 'numat' and their github version).
For our version (see the manual) you install with:
1 ) rm -rf autom4te.cache
2 ) mkdir m4
3 ) aclocal
4 ) autoreconf -i
5 ) automake --add-missing
6 ) autoconf
7 ) ./configure --prefix=${RASPA_DIR}
   or
   ./scripts/CompileScript/make-gcc-local
8 ) make
9 ) make install
