Dear gmx-users, I have installed the gromacs 3.3.3 on a dual core HP workstation with Ubuntu platform. All the programs are properly installed and working except ngmx and dssp. However there is a difference, ngmx is not installed as I donot see the link in /usr/local/bin along with the other programs. where as dssp when executed outputs one pdb file and just hangs for a long time (days) without giving any other output. This is how the output looks: -============================================== Option Type Value Description ------------------------------------------------------ -[no]h bool no Print help info and quit -nice int 19 Set the nicelevel -b time 0 First frame (ps) to read from trajectory -e time 0 Last frame (ps) to read from trajectory -dt time 0 Only use frame when t MOD dt = first time (ps) -tu enum ps Time unit: ps, fs, ns, us, ms or s -[no]w bool no View output xvg, xpm, eps and pdb files -[no]xvgr bool yes Add specific codes (legends etc.) in the output xvg files for the xmgrace program -sss string HEBT Secondary structures for structure count Reading file 1azt_md_grompp.tpr, VERSION 3.3.3 (single precision) Reading file 1azt_md_grompp.tpr, VERSION 3.3.3 (single precision) Opening library file /usr/local/gromacs/share/gromacs/top/phbres.dat Opening library file /usr/local/gromacs/share/gromacs/top/aminoacids.dat Group 0 ( System) has 12245 elements Group 1 ( Protein) has 217 elements Group 2 ( Protein-H) has 161 elements Group 3 ( C-alpha) has 18 elements Group 4 ( Backbone) has 54 elements Group 5 ( MainChain) has 72 elements Group 6 (MainChain+Cb) has 91 elements Group 7 ( MainChain+H) has 92 elements Group 8 ( SideChain) has 125 elements Group 9 ( SideChain-H) has 88 elements Group 10 ( Prot-Masses) has 217 elements Group 11 ( Non-Protein) has 12028 elements Group 12 ( SOL) has 12027 elements Group 13 ( CL-) has 1 elements Group 14 ( Other) has 12028 elements Select a group: 5 Selected 5: 'MainChain' There are 18 residues in your selected group Opening library file /usr/local/gromacs/share/gromacs/top/ss.map trn version: GMX_trn_file (single precision) Reading frame 0 time 0.000 Back Off! I just backed up ddIuI8uU to ./#ddIuI8uU.1# ================================================= I am unable to figure out the problem. Any suggestions are welcome. About ngmx I tried to install it seperately using make and make install but it does not compile/install. How should I install it ? Thankyou for the time. sharada
