hi
i have another question please
in my directory i have another files with different suffix
ls -1
20070131-00800-000012345885858-00.rtp
20070131-00800-000012355885858-00.rtp
20070131-00800-000085765141414-00.rtp
test.lst
i want just the files with the rtp suffix i did something like this
ls -1 | grep -w ".rtp" | awk -F. '{print $1}' > a.log
but it doesn't work
what seems to be the problem ?
thanks for help

g_x2top(1)					 GROMACS suite, VERSION 4.5.4-dev-20110404-bc5695c					g_x2top(1)

NAME
g_x2top - generates a primitive topology from coordinates VERSION 4.5.4-dev-20110404-bc5695c SYNOPSIS
g_x2top -f conf.gro -o out.top -r out.rtp -[no]h -[no]version -nice int -ff string -[no]v -nexcl int -[no]H14 -[no]alldih -[no]remdih -[no]pairs -name string -[no]pbc -[no]pdbq -[no]param -[no]round -kb real -kt real -kp real DESCRIPTION
g_x2top generates a primitive topology from a coordinate file. The program assumes all hydrogens are present when defining the hybridiza- tion from the atom name and the number of bonds. The program can also make an .rtp entry, which you can then add to the .rtp database. When -param is set, equilibrium distances and angles and force constants will be printed in the topology for all interactions. The equi- librium distances and angles are taken from the input coordinates, the force constant are set with command line options. The force fields somewhat supported currently are: G53a5 GROMOS96 53a5 Forcefield (official distribution) oplsaa OPLS-AA/L all-atom force field (2001 aminoacid dihedrals) The corresponding data files can be found in the library directory with name atomname2type.n2t. Check Chapter 5 of the manual for more information about file formats. By default, the force field selection is interactive, but you can use the -ff option to specify one of the short names above on the command line instead. In that case g_x2top just looks for the corresponding file. FILES
-f conf.gro Input Structure file: gro g96 pdb tpr etc. -o out.top Output, Opt. Topology file -r out.rtp Output, Opt. Residue Type file used by pdb2gmx OTHER OPTIONS
-[no]hno Print help info and quit -[no]versionno Print version info and quit -nice int 0 Set the nicelevel -ff string oplsaa Force field for your simulation. Type "select" for interactive selection. -[no]vno Generate verbose output in the top file. -nexcl int 3 Number of exclusions -[no]H14yes Use 3rd neighbour interactions for hydrogen atoms -[no]alldihno Generate all proper dihedrals -[no]remdihno Remove dihedrals on the same bond as an improper -[no]pairsyes Output 1-4 interactions (pairs) in topology file -name string ICE Name of your molecule -[no]pbcyes Use periodic boundary conditions. -[no]pdbqno Use the B-factor supplied in a .pdb file for the atomic charges -[no]paramyes Print parameters in the output -[no]roundyes Round off measured values -kb real 400000 Bonded force constant (kJ/mol/nm2) -kt real 400 Angle force constant (kJ/mol/rad2) -kp real 5 Dihedral angle force constant (kJ/mol/rad2) KNOWN PROBLEMS
- The atom type selection is primitive. Virtually no chemical knowledge is used - Periodic boundary conditions screw up the bonding - No improper dihedrals are generated - The atoms to atomtype translation table is incomplete ( atomname2type.n2t file in the data directory). Please extend it and send the results back to the GROMACS crew. SEE ALSO
