GIFTI converter plugin


This is a brief introduction to the GIFTI-1 converter.

Use of the plugin

This plugin converts between GIFTI (*.surf.gii, *.time.gii, *.func.gii and *.label.gii) and BrainVoyager files (*.srf, *.mtc, *.smp and *.poi). Also, it can write text files of the header information or display header information of the mentioned files in the BrainVoyager QX log tab.

Status of the plugin

This is the fourth version of the GIFTI-1.0 compliant file format converter. Many functions have been added in this and the previous versions, including writing integral files instead of external binary data, exporting currently opened files, importing GIFTI files, replacement of the TinyXML by the giftilib (incl. Expat library) of Rick Reynolds etc.
Also, files with base64 or gzip compressed data can be imported. Files exported to GIFTI are currently in ASCII (text).
Please consult the BrainVoyager support site or the GIFTI project page for updates and tools.
This plugin version is for BrainVoyager QX 2.2 and higher.

Origins

GIFTI is designed by the Geometry subcommittee of NIfTI (chair: Ziad Saad, NIH). This file format is designed to store discrete surface files (triangular meshes) and related file types using XML. GIFTI can be read and written by at least the following software packages: BrainVisa, AFNI/SUMA, CARET, FreeSurfer, CRKIT and VisTrails. The GIFTI project page can be found at GIFTI at NITRC.org.

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) by invitation of the National Institutes for Health (NIH). That format is used to store volumetric data. For more information about the NIfTI-1 format, please consult the NIfTI-1 website.
