책소개

We introduce here MATtrack, an open source MATLAB-based computational
platform developed to process multi-Tiff files produced by a photo-conversion time
lapse protocol for live cell fluorescent microscopy. MATtrack automatically performs
a series of steps required for image processing, including extraction and import of
numerical values from Multi-Tiff files, red/green image classification using gating
parameters, noise filtering, background extraction, contrast stretching and temporal
smoothing. MATtrack also integrates a series of algorithms for quantitative image
analysis enabling the construction of mean and standard deviation images,
clustering and classification of subcellular regions and injection point
approximation. In addition, MATtrack features a simple user interface, which
enables monitoring of Fluorescent Signal Intensity in multiple Regions of Interest,
over time. The latter encapsulates a region growing method to automatically
delineate the contours of Regions of Interest selected by the user, and performs
background and regional Average Fluorescence Tracking, and automatic plotting.
Finally, MATtrack computes convenient visualization and exploration tools including
a migration map, which provides an overview of the protein intracellular
trajectories and accumulation areas. In conclusion, MATtrack is an open source
MATLAB-based software package tailored to facilitate the analysis and
visualization of large data files derived from real-time live cell fluorescent
microscopy using photoconvertible proteins. It is flexible, user friendly, compatible
with Windows, Mac, and Linux, and a wide range of data acquisition software.
MATtrack is freely available for download at eleceng.dit.ie/courtney/MATtrack.zip.
