Dear all:
About one weeks ago, I posted a request about residual analysis
software:
The request was the following:
" I would like to use residual analysis to determine the cutoff
frequency for smoothing data of my research project. Does anyone know of
the pertinent software that is available for public or for academic
use?"
Thanks for all the responses. The following is a summary of the
responses:
1) There is a DATAPAC III which is a comprehensive laboratory
applications
system designed for Windows operating system. Modules are available to
fulfill a broad range of data acquisition, data file management, signal
processing, and data reduction, display, and analysis operations in a
highly
integrated fashion.
You can e-mail them: RunTech@ix.netcom.com
You can also look up the web page: http://www.anaserve.com/~runtech
************************************************** ***********
2) I have freeware available (for power macs) that does this. The
software is
called QuickSAND is found at
http://jaw.fmnh.org/Software/programs.html
************************************************** ***********
3) I think the best option is to write a macro in microsoft excel.
We have a similar system here and it works just fine, use the approach
in winters
1990 book.
************************************************** *********
4) We use Woltring's generalized cross-variance natural B-spline
filter to
do our smoothing. It is able to determine the best cutoff frequency for
smoothing your data and it can handle missing data points in a
continuous set
(e.g. we use infrared markers to track arm movement and Woltring's
program is
able to handle a dataset where the marker went out of view of the
camera).
You can find it and other public domain analysis programs at
http://www.lri.ccf.org/isb/software.
************************************************** ***************
5) Check with http://www.arielnet.com
************************************************** *******
6) I'd be happy to send you the souce code for a program I wrote in C
that
performs a residual analysis for all markers and coordinate directions
independently. You could compile the program and use it, or use the
source as a guide for your own program. Let me know if you would like
it. One note, it is currently written to read data files in the Motion
Analysis Corp. .P3D format.
Thanks to all the responders again
