Extract text from GROMACS trajectory files (TRR)
To convert TRR trajectories to another format, you need GROMACS or other Data software.
To convert other file formats to the "Scientific Simulation Data" file type, you need software like GROMACS or a similar tool.
The .TRR file is a full-precision binary trajectory format generated by the GROMACS molecular dynamics simulation package. Unlike lighter alternatives, a .TRR file typically stores the complete state of a simulation step: atomic coordinates, velocities, and forces.
While this creates a comprehensive dataset for thermodynamic analysis, it results in massive file sizes that quickly consume storage - often gigabytes or terabytes for long simulations. Because the format utilizes the XDR (External Data Representation) protocol for portability, it is strictly binary and cannot be read by standard text editors. Users often encounter friction when trying to share these files or load them into visualization software on varying hardware due to memory constraints.
To overcome these storage and compatibility hurdles, the most pragmatic workflow is converting the file. For long-term archiving or efficient visualization, convert .TRR to the compressed XTC format (which discards velocities and forces to save space). For creating publication-quality renderings or inspecting specific frames in software like VMD or PyMOL, converting to PDB or GRO is essential.
Convert.Guru analyzes your TRR file, detects the exact format, and lets you read the text inside.
Users also converted RTP, ENE, TPB and XTC files.
If you want to convert TRR file to XTC, CSV, JSON, XML, YAML, YML, TOML, INI, CFG, CONF, DAT or DB, you can use GROMACS or similar software from the "Molecular Dynamics Trajectory" category. In the File menu, look for Save As… or Export….
To convert DBF, XML, SQLITE, XLSX, SQL, TSV, ACCDB, YAML, MDB, CSV, ODS or JSON files to TRR, try GROMACS or another comparable tool in the "Molecular Dynamics Trajectory" category.
The history of Convert.Guru began over 25 years ago in California with Tom Simondi’s file-format database. A former contributor to Space Shuttle development and a software pioneer of the 1980s, Simondi established a trusted resource for file type analysis that was even referenced by Microsoft Windows XP. Today, we use modern technology to process and convert thousands of file formats while continually improving our TRR converter.
