Desktop software for patch-clamp raw binary data conversion and preprocessing

Since raw data recorded by patch-clamp systems are always stored in binary format,electrophysiologists may experience difficulties with patch clamp data preprocessing especially when they want to analyze by custom-designed algorithms. in this study,we present desktop software,called pcdreader,which could be an effective and convenient solution for patch clamp data preprocessing for daily laboratory use. we designed a novel class module,called clspulsedata,to directly read the raw data along with the parameters recorded from heka instruments without any other program support. by a graphical user interface,raw binary data files can be converted into several kinds of ascii text files for further analysis,with several preprocessing options. and the parameters can also be viewed,modified and exported into ascii files by a user-friendly explorer style window. the real-time data loading technique and optimized memory management programming makes pcdreader a fast and efficient tool. the compiled software along with the source code of the clspulsedata class module is freely available to academic and nonprofit users. © 2011 ning zhang et al.
