What is an STATS file

STATS files mostly belong to FreeSurfer. STATS files contain statistical and profiling information used by various software. They frequently hold segmentation statistics from imaging tools like FreeSurfer and code analysis data from Python utilities such as Pylint and cProfile.
Depending on the source, these files may also include:

System statistics (for example, macOS system stats or binary performance data)

Statistical exports from applications like SPSS

Video encoding details from tools like x264

Protein disorder predictions in bioinformatics (DisProt)

FilExt.com tip: This file may be plain text, letting you open it with a basic text editor, or it might be binary, which requires the generating software for proper viewing. Check the source application for the best way to open and interpret the data.

How to open STATS files

You need a suitable software like FreeSurfer to open an STATS file. Without proper software you will receive a Windows message "How do you want to open this file?" or "Windows cannot open this file" or a similar Mac/iPhone/Android alert. If you cannot open your STATS file correctly, try to right-click or long-press the file. Then click "Open with" and choose an application. You can also display a STATS file directly in the browser:. Just drag the file onto this browser window and drop it.

STATS file extension format:

If you know the file format, you can also find out how to open or edit the file. Often, the file format can be deduced from the file extension or the initial bytes (called the signature). However, different programs can use the same file extension. Furthermore, a file extension can be renamed incorrectly and double-clicking on it will then display an error when it is opened. So a detailed analysis of a file is vital in order to determine the format and the associated program. In the following you will find our evaluation of the STATS files:

The STATS extension is quite commonly used. The file itself is used by different programs with different formats. The file formats most commonly found in STATS files are:

• 20% of all STATS files use the same file format, which have the signature # T. If you open these files in a text editor, you can view and read the content yourself. The average file size is 9 KB with most files being between 6 KB and 11 KB in size. It is a modern file type. The files contain the following words: # Title Segmentation Statistics, # generating_program mri_segstats, cmdline mri_segstats, mgz --sum stats, --seg mri/aseg.mgz, # cvs_version $Id: mri_segstats.c,v 1.121 2016/05/31 17:27:11 greve Exp $, cvs_version 7 and FreeSurfer. Examples of file names are aseg.stats or lh.aparc.stats. These files can be linked to aparc, wmparc, dktatlas and posta.
• 15% of all STATS files have the same signature 80 04 95. These files are not pure binary files and are therefore readable and interpretable with a text editor. The file size is in the range of 260 bytes to 960 bytes. The following keywords are characteristic: by_module, by_msg, convention, error, fatal, info, refactor, statement, warning, function and method.

All other STATS files (65%) have no consistent format, often e.g. GZIP, moduleq, systemstats, BINd, Total, STATS and SNP. These files sometimes refer to xxxxxx, chess, free, coalitions, fasta or video. Just click the "Choose your .stats file to analyze" button on this page to find out what your STATS file is.
