FD2¶
Contents
Functional Display (32x32, 64x64, 128x128, 256x256) in X11 window.
EPI images in 256x256 Signa format are accepted too.
It displays EPI time or frequency course window.
Usage: FD2 [options] image1, [image2, ..., image10000]
Where options are:
-d display - X11 display
-geom geometry - initial geometry
-nc #_of_colors - initial number of colors [2-200] (def 64)
-sp #_of_degree - range of color spectrum [0-360] degree (def 240)
-gam gamma - gamma correction (1 for no correction)
-num #_of_images - # of images in time course [2-10000].
-im1 image_# - first image in time course. Previous images will be
filled with this one for proper timing of others.
-ideal ref_file - use ref_file for fim-like calculations
-pcthresh # - use # as threshold for correlation
-extra - files after this are not used in time course
(used instead of -num option)
-fim_colors L thr1 pos1 neg2 ... thrL posL negL
- set up L thresholds and colors for FIM overlay
-gsize x y - set graph window size to x by y pixels
-fmag val - magnify scale of FFT by val
-grid val - initial grid separation
-phase - image has negative values (for FFT)
-cf - center image to the frame
-swap - byte-swap data (default is no)
*** this is a new default!
