area - MRI measurement tool
gecon - convert a GE Signa scan series to Silicon Graphics RLE format
fromge - convert a single GE Signa image to Silicon Graphics RLE format
clump - remove isolated high-intensity pixels
colourise - turn a greyscale image into a false-colour image
epicat - concatenate Advanced NMR echo-planar image files

The 2002 release updates these programs to use Michael Sweet's free
implementation of SGI's RLE graphics format, removing all dependencies on
SGI's libimage.  (Note that "area" still depends on the izoom program - if you
happen to have access to the 4Dgifts source code from the IRIX Development
Option, you may want to modify it to link with Sweet's implementation.)

The programs "area" and "gecon" use the XForms library by Mark Overmars and
TC Zhao.  You can find this library at "http://world.std.com/~xforms/", or as
the Debian package "forms-dev".  The code assumes that you have libforms.* in
/usr/lib or /usr/X11R6/lib, and forms.h in /usr/include/X11.

The subdirectory "Old" contains the 1998 release.  You probably won't need
anything from it.

Note:  At some point, General Electric changed their header length for Signa
data files from 14336 bytes to 7904 bytes.  The programs "fromge" and "gecon"
now assume a header length of 7904, but this can be overridden on the command
line (in the case of "fromge") or within the GUI (in the case of "gecon").
