UNLABELLED: Expertomica Cells is a program for the creation and analysis of pedigree plots from time-lapse micrographs of cell monolayers. It enables recording the basic events in a cell cycle, cell neighbourhoods and spatial migration. The output is both numeric and graphical. The software helps to lower main hurdles in the manual analysis of cell monolayer development to practical limits; it reduces the operator processing time of typical experiment containing 5000 consecutive images from the usual 3 months to 3-10 h. AVAILABILITY AND IMPLEMENTATION: Freely available on the web at http://www.expertomicacells.tk or http://www.expertomicacells.wu.cz. The source code is implemented in JAVA 6 and supported by Linux, Mac and MS Windows. SUPPLEMENTARY INFORMATION: Supplementary data available at Bioinformatics online.

UNLABELLED: Mass spectrometers are sophisticated, fine instruments which are essential in a variety applications. However, the data they produce are usually interpreted in a rather primitive way, without considering the accuracy of this data and the potential errors in identifying peaks. Our new approach corrects this situation by dividing the LC-MS output into three components: (i) signature of the analyte, (ii) random noise and (iii) systemic noise. The systemic noise is related to the instrument and to the particular experiment; its characteristics change in time and depend on the analyzed substance. Working with these components allows us to quantify the probability of peak errors and, at the same time, to retrieve some peaks which get lost in the noise when using the existing methods. Our software tool, Expertomica metabolite profiling, automatically evaluates the given instrument, detects compounds and calculates the probability of individual peaks. It does not need any artificial user-defined parameters or thresholds. AVAILABILITY: MATLAB scripts with a simple graphical user interface are free to download from http://sourceforge.net/projects/expertomica-eda/. The software reads data exported by most Thermo and Agilent spectrometers, and it can also read the more general JCAMP-DX ASCII format. Other formats will be supported on request, assuming that the user can provide representative data samples.
