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!

Events:

Program quit : <q> or <Q> Change to colors : <C> Change to B & W : <B> Swap colors : <s> Restore colors : Button_3 at image center Squeeze colors : #2 or #3 button - right side of image Expand colors : left side of image Circ. color bar : #2 or #3 button at the color bar Color saturation : #2 or #3 button - the top or bottom Exact image number: press <I>, enter_number, <CR> First image : 1 Last image : l Next image : > Previous image : <

dragging red pointer works too

Save current image to a file : press <S> Save averaged image (not norm) : press <X> Position frame in the image : press Button_1 in the image area,

drag cursor, and release button.

Center frame on desired pixel : press Button_1 over desired minigraph. Rotate image 90 deg. clockwise : press Button_3 in [Rot] window.

counterclockwise : press Button_1 in [Rot] window.
Change to differential display : press [Diff] window. Set first and
last image for averaged reference.

Average of set of images : press [AvIm] (can be used in Diff mode). Compute FIM overlay : press [FIM], choose ref file,threshold,

then press [GO]
