The TRR file is supported on 1 operating systems. Depending on your operating system, you may need different software to handle the TRR files. Below is a summary of the number of programs that support and open the TRR file on each system platform.
What is TRR file?
The TRR file has been categorized as Misc Files. The author of this format is Gromacs. Additionally, the Misc Files category contains 6033 of other files. GROMACS Full-precision Trajectory is supported by 1 operating systems. The file will work on Windows systems, unfortunately not on others. It is recommended to use Gromacs to handle this file. This is a program created by Gromacs.
How to open TRR file?
The most common problem when using GROMACS Full-precision Trajectory is that a specific TRR is not associated with the program. This is manifested by the fact that TRR files open in unusual applications or do not have an assigned program. How to solve such a problem?
The first thing you should do is just "doubleclick" on the TRR file icon you want to open. If the operating system has an appropriate application to support it and there is also an association between the file and the program, the file should be opened.
Step 1. Install Gromacs
The first step is to check if the computer has the Gromacs program installed. The easiest method is to use the system search engine by entering the program name Gromacs in it. If it is not, installation may solve the problem, as most applications create file associations during installation. Below you will find a list of applications that support TRR files.
Programs to open TRR file
Remember to download programs supporting TRR files only from verified and safe sources. We suggest using the websites of software developers.
Step 2. Create association of Gromacs with TRR files
If, despite the installed application, the TRR file does not start in the Gromacs application, you must create a file association. This option is available from the level of Properties of a specific file available in the context menu. The window will show, among other things, the type of the file and the information by which the program is used to launch the file. Using the "Change" button we can select the desired program. If there is no software on the list, simply select "Browse" and manually select the directory where the application is installed. Checking the "Always use the selected program ..." box will permanently associate the TRR file with the Gromacs program.
Step 3. Update Gromacs to the latest version
If, however, after binding Gromacs with GROMACS Full-precision Trajectory there were still problems, you should update the program to the latest version. Some applications allow you to update from the program level, and for others you need to download the installer from the Gromacs page and install.
Step 4. Check for the following problems with the TRR file
Of course, it may happen that despite the above steps, the file still does not work. This could be due to the file itself, the cleanest issues are:
Very often, the file may be size 0 or incomplete. Usually this applies to TRR files downloaded from the Internet in case the download did not finish properly. Downloading the file again should fix the problem.
The most common cause here is computer viruses. A virus scan using an up-to-date antivirus program should fix the problem. Some antivirus vendors also provide free online scanners. For the best results, we will scan the entire operating system, not just our TRR file. As a result of the scan, sometimes it is not possible to recover TRR files, which are deleted if there is a backup of this file, then after restoring it, it must also be scanned.
Older version of TRR file may not always be supported by the latest software version. These problems are known and are often very easy to fix using the software developers's website.
There can be many reasons for the failure. Repairing is very dependent on the file type. Some programs offer the option of recovering data from damaged TRR files. The easiest way is to restore the file from a backup, if there is one, or contact Gromacs
The program can also signal the fact of encryption. The encrypted file TRR except for the special designation, works normally, but only on the device where it was encrypted, before transferring it to another machine, decryption is required.
Some of the system directories are excluded from modification. These directories are write-protected to them and it's very hard to fix this problem. If possible, you can try to move the TRR file to another location.
This problem usually affects more complex files. Some file types can only be opened in one program at a time. Just close unnecessary programs. If the error persists after closing other programs, wait for a while. However, some background programs may block the TRR file while scanning. If this does not work either, restart the device.
