vecview(1) graphical viewer for 1D (vector) or 2D (matrix) data


vecview [<flag> ...] <file> ...


vecview is part of the VoxBo suite of tools for brain image analysis.

vecview allows you to view and explore one or more 1D vectors, or a single 2D matrix. Command line options allow you to concatenate vectors. Options in the graphical interface allow you to switch among multiple vectors or to view them all simultaneously. You can also view the power spectrum of the vector.

The following keys are recognized by the grapher. The up arrow and down arrow let you zoom in or out. The tab key lets you switch between vectors when more than one is displayed. The shift key lets you see interpolated values (otherwise, clicking on the graph snaps to the nearest point). F1 through F4 select view modes.

To get a list of command line flags, run the program with no arguments.


Pre-built VoxBo binaries are available for Linux, OSX, and Cygwin, and via the NeuroDebian project ( for Debian derivatives.
