The atp file contains general information about atom types, like the atom Tng, xtc, trr, gro, g96, or pdb Energy files ¶ eneĮnergies, temperature, pressure, box size, density and virials (binary) edrĮnergies, temperature, pressure, box size, density and virials (binary, portable) Generic energy formats:Įssential dynamics constraints input for gmx mdrun epsĪscii matrix data, use gmx xpm2ps to convert to eps xvg X only (ascii, reduced precision) Formats for full-precision data: X only (compressed, portable, any precision) gro #VECTOR MAGIC 1.15 FINAL PORTABLE FULL# Number and the mass in atomic mass units. The arn file allows the renaming of atoms from their force field names to the namesĪs defined by IUPAC/PDB, to allow easier visualization and identification. Including extended thermostat/barostat variables, random number states The complete state of the simulation is stored in the checkpoint file, The cpt file extension stands for portable checkpoint file. The dlg file format is used as input for the gmx view To categorize all data file formats, GROMACS has a generic file format called With domain decomposition also the some decomposition setup informationįiles with the dat file extension contain generic input or output. Grid 39 18 edi ¶įiles with the edi file extension contain information for gmx mdrun These files are not meant to be altered by the end user. It used to be possible to generate those through the options To run Molecular Dynamics with Essential Dynamics constraints. The edr file extension stands for portable energy file. The energies are stored using the xdr protocol. ![]() The ene file extension stands for binary energy file. The file can be transformed to a portable energy file (portableĪcross hardware platforms), the edr file using the program It holds theĮnergies as generated during your gmx mdrun. The eps file format is not a special GROMACS format, but just a #VECTOR MAGIC 1.15 FINAL PORTABLE PORTABLE# It shows the secondary structure of a peptide as a functionĪ file with the g96 extension can be a GROMOS-96 initial/finalĬonfiguration file or a coordinate trajectory file or a combination of both. Velocity (in nm/ps (or km/s), x y z in 3 columns, each 8 positions with 4 decimal places) Position (in nm, x y z in 3 columns, each 8 positions with 3 decimal places) GROMACS supports the following data blocks in the given order: The file is fixed format, all floats are written as 15.9 (files can get huge). When building hydrogen atoms that were either originally missing, or that The hdb file extension stands for hydrogen database Note that this is the format for writing, as in the above exampleįields may be written without spaces, and therefore can not be read Without using the GROMACS libraries you can use the following formats: C format If you want to write such a file in your own program Note that separate molecules or ions (e.g. ![]() The m2p file format contains input options for theĪre very easy to comprehend when you look at the PosScript(tm) output Logfiles are generated by some GROMACS programs and are usually in The itp file extension stands for include topology.
