Latest Installation Package
(available to web-registered users)

Version 4.2.1

Matlab routines
(available to web-registered users)

SLControl's Analysis->Single_Data_File window has useful cursor controls and a number of curve-fitting options. There are also a few automated procedures available under Analysis->Batch_Analysis for those dealing with lists of files. These tools should be adequate for most users.

For those wanting to do something a little less straightforward, an attractive option is to import the data files (which are after all carefully formatted text files) into third-party software and do their analysis there. I use Matlab for this most of the time and have developed a number of routines which SLControl users may find helpful.

Details for each routine are included at the top of each *.m file. Please contact me if you need further help or discover any bugs. I'd also encourage anybody who has developed their own SLControl-relevant routines to share them with other users. I'd be delighted to post them here.

load_slcontrol_file.m
(8 kB) 21 March, 2005
data_file=load_slcontrol_file(vargin)
Reads a specified SLControl file (*.slc) and returns selected parts of the header information in a structured array.

display_slcontrol_record.m
(6 kB) 21 March, 2005
display_slcontrol_record(varargin)
Useful utility for quick display of SLControl records.

transform_slcontrol_record.m
(2 kB) 9 February, 2005
transform_slcontrol_record(data)
Duplicates SLControl->AnalysisDisplay->Transform->Change to Calibrated Values in the Matlab environment

analyse_ktr.m
(12 kB) 22 March, 2005
results=analyse_ktr(vargin)
Canned routine for extracting half-times, single and double exponential rates, residual force etc.

directory_display.m
(2 kB) 16 June, 2005
directory_display
Simple code takes all the SLControl records below a given directory and superposes them on scaled axes.
Code includes copies of SubDir and Dir written by Tim Myers and Paul Macey respectively and freely available at the Matlab Central FileExchange

sl_calculation.zip
(246 kB) 30 January, 2005
This zipped archive contains a GUI-based Matlab algorithm which calculates the sarcomere length in a user-selected region of a 'muscle' picture by fitting a damped sine-wave to the averaged autocorrelation. Contact Ken if you need further details.

Other Utilities
(NOT available to web-registered users)

SLConvert.exe (205 kB)
A DOS-based utility which converts data records collected with our original "Fiber" program to the SLControl format.
(Note this program is almost certainly only of use to members (or former members) of the Moss lab at the University of Wisconsin.)

SLControl is provided with the best of intentions, but there is no guarantee that it works correctly under all condition. When new problems are discovered, they are reported on this siteand every attempt is made to fix the problem in future releases. Nevertheless users who chose to use SLControl do so at their own risk. No warranty is implied or intended. Last updated on 16th June, 2005 by Ken.
