About VOI files

VOI files, commonly associated with the BrainVoyager software, are specialized file types used primarily in neuroimaging to define volumes of interest within brain scans. While these files play a crucial role in research, converting them to more widely-used formats can be challenging due to their specificity and complexity.

Conversion of VOI files often requires specialized software. Some popular desktop applications include BrainVoyager and FSL, both of which offer tools for exporting VOI files to formats like NIfTI (.nii) and Analyze (.hdr/.img). However, these tools can be intricate and demand a steep learning curve.

Converting VOI files to other formats such as .nii, .hdr/.img, or even .jpg for visual presentations is essential for broader accessibility and usability. Yet, users should be aware of potential issues such as data loss or misrepresentation during conversion, which can affect the accuracy of the data when used in different applications.

One of the major drawbacks of VOI files is their limited compatibility with non-specialized software, which can hinder collaboration and data sharing. This limitation underscores the importance of converting VOI files into more universally accepted formats.

For those who wish to bypass the complexity of these desktop applications, Convert.Guru provides a seamless solution. Simply drag and drop your VOI files onto the webpage, and convert them into a variety of formats with ease. While Wikipedia provides more technical insights into VOI files, Convert.Guru ensures a user-friendly experience, making file conversion accessible to everyone.


The VOI Converter Story

The history of Convert.Guru began more than 25 years ago in California, when Tom Simondi published the most comprehensive database of file formats on his website. Before that, Tom had worked on Space Shuttle development at the Air Force Systems Command’s Space Division in Los Angeles. He is known as one of the top programmers of the late 1980s.

When Microsoft integrated Tom’s Filext database into Windows XP, it became the leading platform for analyzing and processing file types and formats.

Today, we use the latest technologies to analyze, process, and convert one of the world's largest collections of file formats. We are committed to developing the best VOI converter by continuously improving quality, usability, and reliability.
