[From nobody Thu Nov 14 11:50:14 2013 Date: Mon, 10 Nov 2008 10:59:39 +0200 From: "Gadzikano Munyuki" <Gadzikano.Munyuki@uct.ac.za> To: <gmx-users@gromacs.org> Subject: Re: gmx-users Digest, Vol 55, Issue 51 Mime-Version: 1.0 Content-Type: text/plain; charset=US-ASCII Content-Transfer-Encoding: quoted-printable Content-Disposition: inline I have checked the source code and it looks like g_spatial has been = replaced by g_cluster.I got the code below under g_spatial.c /* This is just a wrapper binary. * The code that used to be in g_cluster.c is now in gmx_cluster.c, * where the old main function is called gmx_cluster(). */ int main(int argc, char *argv[]) { gmx_cluster(argc,argv); return 0; } Gadzikano -- original message -- I am not sure what is going on in this case. You could try: which g_spatial to see what is being picked up. You could also try to move the =20 g_spatial executable to its own directory and then execute g_spatial =20 from that path: /new/path/to/executable/g_spatial -h ls /new/path/to/executable/g_spatial g_spatial Otherwise I am not sure what is going on. Are you sure that you didn't =20 compile g_cluster under the name g_spatial by accident? Chris. -- original message -- HI Chris I followed the steps below and when i tried to run g_spatial it =20 executed g_cluster instead. Even when i do g_spatial -h it looks like =20 its being overwritten by g_cluster 1.I used make_ndx to create a group containing the atoms around which i = want the SDF 2. trjconv -s md.tpr -f tyrc_md.trr -o tyrc1.xtc -center tric -ur =20 compact -pbc none 3. trjconv -s md.tpr -f tyrc1.xtc -o tyrc2.xtc -fit rot+trans 4. g_spatial -s md.tpr -f tyrc2.xtc -n index.ndx ------------------------------ ]
