Early versions of the installation packages in this archive include the full source code for SLControl. Unfortunately this code includes some curve-fitting routines from Numerical Recipes which (while freely distributable as part of an executable file) cannot be made publicly available. Such packages cannot be downloaded by users who have registered automatically via the web interface. If you would like to ask specific questions about any of the code in SLControl please contact Ken for more information.

Version 4.0.1_ns (10 MB) 9 July, 2003

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. Needs the trivial sub-functions single_exponential_recovery_fit.m (1 kB) and double_exponential_recovery_fit.m (1 kB).
	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. Requires SubDir and Dir written by Tim Myers and Paul Macey respectively and 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.

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.)
