title: A modular program for analysis of electrophysiological data on a laboratory minicomputer.
abstract: In the study of electrophysiological phenomena, the signals to be investigated are often reduced to sampled time series or point processes. Nowadays, the measuring equipment frequently includes one or more micro- and/or minicomputers which perform the data acquisition (including, e.g., A-D conversion and interval measurements) and the subsequent data processing and analysis. This paper describes the structured organization of data measurement and analysis of electrophysiological data performed by a modular software program implemented on a laboratory minicomputer. The program is used in our clinical laboratory by a number of research teams with different experimental objectives. The input data structure for the program has a standardized format, comprising multiplexed data channels preceded by a 256 entry parameter block containing general processing information and specific information concerning the analyses performed. The tasks carried out by the program are the calculation of distributions and correlations, digital filtering and estimation of spectra. The program can easily be extended by writing new software modules.
