MMF2MWT allows command line processing of MMF compressed video files using Rex Kerr's Multi Worm Tracker.

The code for the command line program and the command line program (mmf2mwt.exe) are found in the MWTMMF directory.  mmmf2mwt.exe can be called with several options:

mmf2mwt.exe pathToImageStack\imagestackname.mmf will use default settings and produce output as 

pathToImageStack\TODAYSDATEANDTIME\imagestackname_NNNNNk.blobs
pathToImageStack\TODAYSDATEANDTIME\imagestackname.summary

default settings can be adjusted by editing the file
defaultMWTSettings.txt, which is produced when the program is run for the first time

other options can be found by running mmf2mwt with no arguments

-----
explanation of settings:
these are the default settings, with explanation


frame_rate: 30 
	mmf was recorded at 30 frames per second

thresholdToFillObject: 50 
	blobs are filled out to this threshold level (gray levels above background) 

thresholdToMarkObject: 70
	blobs must contain pixels above thresholdToMarkObject to be marked 

minObjectArea: 10
minNewObjectArea: 30
maxNewObjectArea: 20000
maxObjectArea: 30000

	new blobs must be between 30 and 20,000 pixels in area.  To avoid dissapearing, a blob must maintain its area between 10 and 30,000 pixels

startFrame: 0
endFrame: -1

	mmf frame to start analysis (default 0: )
     mmf frame to end analysis (if <0, process all frames)

adpatationAlpha: 8
dancerBorderSize: 10
minFramesObjectMustPersist: 60
updateBandNumber: 16

	mwt settings you will probably not need to adjust.  
	each frame contributes 2^(-adaptationAlpha) towards updating the background.  
	ask Rex about dancerBorderSize.  
	we don't write out objects that lasted less than minFramesObjectMustPersist.  
	ask Rex about updateBandNumber

windowOutputUpdateInterval: -1
writeLog: false

	If windowOutputUpdateInterval > 0, we show a window with the current state of the MWT every windowOutputUpdateInterval frames.  The red and green channels are the original image from the MMF; the blue channel is the output of the MWT showObjects function.  Untracked objects will appear yellow.  This operation takes about 5 times as long as all the other operations put together, so set windowOutputUpdate to a larger number (e.g. 30) if you plan to use it.

	if writeLog is true, we dump some text output containing diagnostic information to outputpath/outputprefix.mwtlog
otherwise, we dump it to cout

getting the code
This code comes as a git module with submodules.  One of the submodules also has a submodule.  

To get all of the code, using the git shell:

git clone [email protected]:samuellab/MMF2MWT.git
cd MMF2MWT.git
git submodule update --init --recursive

This code has a netbeans project (in MWTMMF/nbroject) configured for Windows32 and mingw and for Linux and g++.  It requires Netbeans 7.1 with the c++ package. Netbeans and help installing it for your platform are available from netbeans.org

The file MWTMMF/WindowsBinaries/mwt2mmf.exe is a compiled windows command line program, which should work on any modern windows system.
