TScratch download

TScratch is a software tool developed to automatically analyze wound healing

assays (scratch assays). It is available as a stand-alone application using

Matlab Compiler on Macintosh (Intel) OS X and PC (Windows) platforms. The

downloadable files below are available in two forms, one including the Matlab

Compiler Runtime (MCR) v7.8 engine, and one without it. If MCR 7.8 is not

installed on your computer, you will need the form including MCR. If you

already have MCR 7.8 installed (for example if you have MATLAB R2008a with

Matlab Compiler; you can check which version of MCR you have by writing

'mcrversion' at the MATLAB prompt), you can download the smaller file.

The manual with installation instructions is included in the zip-files

(TScratch_manual.pdf), but is also available here:

http://www.cse-lab.ethz.ch/wp-content/uploads/2017/12/tscratch_manual.pdf.

Some troubleshooting hints are provided below.

The following TScratch packages are available at our repository.

Macintosh (Intel)

Please download the proper file and extract it using Archive Utility

(tscratch_nomcr_pkg.zip - a version which requires the user to have Matlab

Compiler Runtime (MCR) v7.8 installed (3 MB), tscratch_pkg_simple.zip - a

stand-alone application, includes MCR (206 MB)). The second file can be downloaded

from here: http://www.cse-lab.ethz.ch/wp-content/uploads/2017/12/tscratch_pkg_simple.zip.

Open TScratch_manual.pdf and read further installation instructions there. The installation procedure was

developed by Will Ashby, Vanderbilt University.

According to the Installation Instructions included in the second file (tscrach_pkg_simple.zip),

the Matlab runtime (v78) must be installed first and then TScratch must be copied into the Application folder.

The older version of the Matlab runtime does not interfere with the existing Matlab installation.

Moreover, you must have XQuartz installed (https://www.xquartz.org/).

TScratch might fail to start (e.g. macOS Sierra) due to a missing function in libz.1.dylib.

In that case delete that file from the /Applications/MATLAB/MATLAB_Compiler_Runtime/v78/bin/maci folder.

Windows

Please download the proper file and extract it (tscratch_nomcr_win.zip - a

version which requires the user to have Matlab Compiler Runtime (MCR) v7.8

installed (3 MB), tscratch_win.zip - a stand-alone application, includes MCR

(231 MB)). The second file can be downloaded from here:

http://www.cse-lab.ethz.ch/wp-content/uploads/2017/12/tscratch_win.zip.

Then double-click on TScratch_win.exe to unpack the program and

install MCR (if the version with MCR was downloaded). Then run TScratch.exe to

start the program. To the best of our knowledge the software works in Windows

XP, Vista and Windows 7. It was not tested on Windows 8, but might work there

too. We advise that you download and install the version with MCR in any case,

since it will be incompatible to more recent Matlab versions. In short you

should download the the Windows version with MCR, unzip it and execute the

resulting 'TScratch_win' executable. This will only install MCR and should run

without errors. You can then execute the 'TScratch' executable.

Troubleshooting

We have observed that on some machines depending on what is already

installed, some libraries are not automatically installed. In such cases

TScratch may fail to open without showing any errors. If this happens try

the following: Find where MCR was installed (by default this is in

'C:Program Files (x86)MATLABMATLAB Compiler Runtimev78') Within that

folder, you can find 'vcredist_x86.exe' in the folder 'binwin32'. Run this

to install the missing libraries.

Source Code

You can also download the source code of TScratch (TScratch_src.zip). You will

need Matlab (R2008a or newer) and the CurveLab library (available at

www.curvelet.org) to run it. Please consult the README file included in the

source code package for further instructions.

Sample data set

This zip-file contains a sample data set from a wound-healing experiment:

[tscratch_sampledata.zip](http://www.cse-lab.ethz.ch/wp-content/uploads/2017/12/tscratch_sampledata.zip) (5 MB).

Download and unpack it to try out the TScratch program on some real data.

Authors

TScratch was developed by Tobias Gebäck and Martin Schulz, ETH Zürich. The

Software is provided as-is, but very limited support might be provided by the

current members of the CSE lab (www.cse-lab.ethz.ch).
