Abstract
A software package, MotAn, has been developed for off-line analysis of gastrointestinal pressure recordings. The program has been implemented in the Modula-2 language for use on IBM personal computers. The program includes capabilities for manual or automatic detection of contractions, calculation of frequency and intercontractile intervals, area of contractions, motility index, concordance and cross-correlation analysis for detection of artifact and for propagation analysis. The program has been applied on pressure recordings from the stomach and duodenum as well as on the rectum and the urinary bladder. Besides the basic part of the program, it is possible for the experienced programmer to add new blocks of object code for development of special analysis procedures.
