What is a .STATS file?
The file extension .STATS is associated with a FreeSurfer Statistics File. This type of file is created by FreeSurfer, which is a specialized software tool used primarily for analyzing and visualizing brain images derived from MRI (Magnetic Resonance Imaging) scans. The .STATS file contains important data that FreeSurfer generates during its processing. This includes subcortical segmentation data, which is often saved as aseg.stats, and cortical parcellation data, typically saved as aparc.stats. These data sets are crucial for studying different regions of the brain and are used to produce detailed brain images.
The .STATS files are stored in a plain text format. This means you can open them with basic text editing software, but to fully understand and utilize the data, specific knowledge of the file structure and contents as outlined in the FreeSurfer documentation is necessary. This documentation provides detailed explanations of the data format and how to interpret the various statistics and values contained in the file.
To open a .STATS file, you can use the program Surfer, which is designed to handle such files. Surfer can interpret the statistical data and help visualize it, making it easier to analyze the brain imaging results. This program is particularly useful for researchers and professionals working in fields related to neuroimaging and brain analysis.
In summary, a .STATS file is a critical component in brain imaging analysis with FreeSurfer, containing detailed statistical data about the brain's structure. It can be opened and utilized using specific software like Surfer, which supports the interpretation and visualization of this complex data.
