NIfTI-1 converter plugin
This is a brief introduction to the NIfTI-1 converter.
Origins
NIfTI is the successor of the Analyze 7.5 data format that was designed by the Mayo Clinic (Rochester, USA). NIfTI is a designed by the Data Format Working Group (DFWG; chair: Stephen Strother) by invitation of the National Institutes for Health (NIH).
The format is used to store volumetric data.
For more information about the format, please consult the NIfTI-1 website.
Use of the plugin
This GUI plugin presents a tabbed dialog for easy processing using BrainVoyager's internal plugin access functions.
This means that a file (*.vmr, *.vmp, etc) needs to be currently open in BrainVoyager QX before it can be exported.
For importing, it is only necessary to have a *.vmr open when importing to images with bounding boxes (currently only *.vtc).
A manual with the functions that are offered in the NIfTI-1 converter plug-in
has been placed in the "GettingStartedGuides" sub-folder in the main "BrainVoyager QX" folder during installation; the manual can also be found on the BrainVoyager NIfTI & GIfTI page on the BrainVoyager wiki and support web site.
Status of the plugin
The plugin will import and export most file formats, however the positioning information is work in progress.
Please consult the BrainVoyager wiki for updates and tools.
This plugin version is for BrainVoyager QX 2.0.
Background information
This version of the converter (1.08.180610) is using the BrainVoyager QX plugin access functions for file I/O. While the previous version was mainly written in C, this version is designed to optimally benefit from the advantages of C++.
The technical design of the converter can also be downloaded from the BrainVoyager NIfTI & GIfTI page on the wiki.
