Beta Testers Wanted for Stanford Center for 
Tuberculosis Research Molecular Fingerprint Analyzer
(SCTR-MFA) version 0.4.2! 

SCTR-MFA runs an error analysis program on replicate strain fingerprint 
data, which in turn recommends a method to compare lanes, and calculates 
parameter values to use with comparison methods. SCTR-MFA also
includes programs to compare fragment length data using one of 
two methods (Align-and-Count or Interpolated Error), calculate 
genetic distances, and create lists of clustered fingerprints 
(a number of rules are provided). SCTR-MFA is extensible to 
include third-party or user-developed comparison methods,
genetic distance calculators, and clustering rule programs. 

SCTR-MFA does not currently present data visually (e.g., with lane
maps), nor does it perform cluster refinement. The following reference 
describes the Align-and-Count Method, introduces the clustering
approach used by the software, and describes cluster refinement:

Please register and download SCTR-MFA if you would like to test 
this software for Windows 95/NT. If you would like the command 
line programs (which perform all the analyses) for Unix
operating systems, please email me hugh at
