FIbeR Extraction (FIRE)
Andrew M. Stein
March 5, 2009

Introduction
------------

FIRE is a Matlab tool for automatically extracting the network geometry for a
stack of confocal microscope images of a semiflexible polymer gel, such as
actin, fibrin or collagen. It works best when the polymer is fluorescently
labeled, though less good results can be achieved from reflectance images. The
is discussed in detail in:

  A.M. Stein, D.A. Vader, L.M. Jawerth, D.A. Weitz, and L.M. Sander.
  An algorithm for extracting the network geometry of 3d collagen gels.
  J. Microscopy, 232(3):463, 2008.

The manuscript is included with this documentation. The appendix lists the
parameters used by the algorithm. FIRE requires Matlab and the Matlab image
processing toolbox. To test the algorithm, open Matlab and change to the
FIRE/example directory in Matlab. Then, type "go example small" at the Matlab
prompt for a quick test (36 s on a 2 GHz MacBook Pro). For a larger data set,
run "go example" (19 min). When applying FIRE to new data sets, the user is
encouraged to start with small images and look at the plots generated by "go
example small" to understand what parameters should be altered to improve the
performance.
