List Launcher is a utility that is designed for quick, simple and logical access to commonly used folders, files, applications, desk accessories or any other type of file. It also provides a utility for quickly moving between different open applications.
List Launcher is an application. This means that in order to use List Launcher you need to make it the active application, but it also means that it can be enabled or disabled without ever restarting your computer. List Launcher provides several convenient methods for accessing and launching files and switching between active applications, even when it isn't the active application.
BranChing is a program which allows you to quantitatively analyze digitized images of branching structures. Originally designed for analyzing plant root systems, BranChing can also been used for fungal mycelia, neuronal dendrites, river drainage systems, and any other type of branching structure for which can be obtained digitized, computer images. BranChing has two general types of output. First, BranChing takes uses binary tree data structures to describe the branching structures, and these binary trees can be stored in TEXT files for later retrieval by BranChing or any other software which can read BranChing's output binary tree format. A sample pascal project which demonstrates how to convert the TEXT file output from BranChing into a binary tree is available.. Second, BranChing can calculate a large number topological and architectural indices for characterizing branching structures. A technical description of BranChing and the reliability of its measurements are provided in Berntson (1992). This version has been significantly expanded - it now includes a comprehensive set of options for topological and architectural analyses of bifurcating branching structures, including pathlength measures (Berntson 1995), link-type classification, tree-asymmetry measures, and a variety of order-size metric scaling parameters (Berntson 1996, 1997).
This program consists of several modules for making measurements of digitized images of plant roots.
Trajectories
This module is used for measuring vectors along curves (it works manually). A potential application is to generate functions of length-angle relationships for trajectories of root growth obtained from rhizotron or excavation studies.
Root Length
Measures length of randomly distributed group of lines. Uses algorithms introduced by Newman (1966) and modified by Harris and Campbell (1989).
Fractal
Calculates fractal dimension of two dimensional images using the grid intercept method. For v1.1d (and greater) and greater, this module has been completely rewritten. The output from this module can be post-processed by an additional program (FDResidAnal) to derive spatially corrected estimates of D.
Pixel Types
Counts all the on pixels in an image and for each on pixel, counts the number of neighboring pixels. For previously skeletonized images (e.g. ones skeletonized in Image) this routine will tell you "length" (all pixels), possible "tips" (one neighboring pixel), possible branching points (more than two neighbors), and noise (no neighbors). This program also performs root length calculations developed by Pan and Bolton (1991).
This is an alpha-version of a program for calculating root production and loss dynamics from sequential in situ images of roots. This program is under development. Documentation is limited (as on-line help), but available. If you are interested in this program, dowload it, check it out, and let me know. I'll help you get it up and running.
This program performs the analysis of deriving the appropriate spatial scales over which an image exhibits self-similarity, and then calculates a fractal dimension which corresponds to this finite range. This program REQUIRES RootLength+. It processes the raw output of box sizes vs box counts which RootLength+ creates when calculating fractal dimensions. A detailed description of how this program works is given in a forthcoming paper in Proceedings of the Royal Society, Biological Sciences .
