Disp
controls the way images are displayed and saved.
This may need to go on its own page!
It pops up its own control window and most controls change image
immediately.
Orientation controls at top allow you to flip image around.
+ LR Mirror
flips the image left to right. For example, if the
image was displayed left=Left
it will flip to left=Right
No Overlay
lets you turn color overlays off (crosshairs; function)
Min-to-Max
Intensity bar is data min-to-max.
2%-to-98%
Intensity bar is smallest 2% of data to largest 98%.
This avoids having a few very bright voxels dominate intensity
scaling.
Free Aspect
lets you distort image shape freely. Otherwise, AFNI
tries to keep image shape true as you stretch/shrink window.
The save panel controls how images are saved to disk. For more
details, (see below)
All buttons off: saved image file contains slice raw data.
(not what you want)
Nsize Save
: same, but images are 2N in size.
PNM Save
: images are saved in PPM/PGM format (color/gray).
Save to .xxx(s)
: saves image(s) to specified format.
Save One
: for saving montage.
Save Anim GIF
will save an animated .gif file scrolling
through the slices of the image.
Project
applies a projection function to plus-or-minus ‘Slab’
images from each pixel.
Slab +-
selects the number of slices around the current view to
use for the projection. Useful for looking at blood vessels and
other different images.
Tran 0D
lets you transform voxel values before display. Log10
and SSqrt
are useful for images with extreme values.
Tran 2D
provides some 2D image filters for the underlay only.
Median 9
smoothing can be useful for printing images.
RowGraphs
are plots of the underlay (grayscale) image intensity
as x vs. y graphs.
Each graph is from one displayed horizontal row of
the image.
The bottom rowgraph is from the image row under the crosshairs.
Upper rowgraphs are from higher image rows.
Image transformation functions and image rotation/flips will affect
the rowgraphs as well as the image display.
The color marker indicates the crosshair focus point and can be
hidden with the No Overlay
button.
If you want columns, flip the image with CCW 90
.
Surfgraph
lets you graph the voxel values in a surface graph.
Extra imaging processing filters are provided at the bottom.
