Hello, I am trying to simulate a lipid membrane with Gromacs. I am trying to generate the *.tpr file o run the simulation, but every time I use the command grompp I got the following error:
checking input for internal consistency... ...ling /usr/bin/cpp : No such file or directory cpp exit code: 32512 dppc128.top > gromppzJXISa'cpp ' command is defined in the .mdp file ************************************************************* * Important: if you do not have a c-preprocessor installed, * * you MUST run grompp with the "-pp" command line option * * in place of the "-p" option. * ************************************************************* processing topology... processing coordinates... ------------------------------------------------------- Program grompp, VERSION 3.3.3 Source code file: ../../../../src/kernel/grompp.c, line: 469 Fatal error: number of coordinates in coordinate file (dppc128.gro, 17365) does not match topology (dppc128.top, 0) ------------------------------------------------------- "One Cross Each" (Monty Python) I don´t where the problem is, I've already checked the cpp compiler and it installed in the /usr/bin/cpp, as I put in the .mdp file. In the topology file I have the following lines: ; ; File 'dppc128.top' was generated ; By user: onbekend (0) ; On host: onbekend ; At date: Tue Aug 18 10:02:52 2009 ; ; This is your topology file ; Pure DPPC bilayer with 128 lipids and 3655 water molecules ; ; The force field files to be include #include "ffoplsaa.itp" ; Include DPPC topology #include "dppc.itp" #include "lipid.itp" #include "spc.itp" [ molecules ] ; Compound #mol DPP 128 SOL 3655 If anyone can help It will be very nice, Thank you very much so far, Cíntia C.
