Software (Obsolete page)

CHART is the software package, running under DOS, designed to control data acquisition by the MIFE hardware system. This software allows automated and interactive real-time control of the amplifier configuration and the micromanipulator while the data is being collected and written to disk. The system configuration is recorded together with the data, and all modifications during data acquisition are recorded in a log file which can also include annotations typed during the experiment. Up to 8 channels of data are displayed on the screen as if on a chart recorder. Any region of the “chart” can be inspected (and expanded or contracted) at will without interrupting the measurements. The software allows subsequent recall and display of any run. It also allows the export of the raw or averaged data in the form of an ASCII file for import into a spreadsheet or other program. 

The system will also function as an excellent electrometer/recorder with a 10 Hz bandwidth for microelectrode studies of membrane potential or for any other data acquisition. This application is illustrated by a screen dump of the CHART display for an example of surface electric potentials of corn leaves responding chaotically to rhythmic light. 

MIFEFLUX  takes output files from CHART and produces convenient ASCII text files for spreadsheet importing.
