Action potential analysis
sigap.zip 4,001

This script will analyse action potential data off-line. For each frame of data, the following data values are recorded in the results file: DMP (diastolic membrane potential), UA (upstroke amplitude), APD (action potential duration) at 30%, 60% and 90% re-polarisation from magnitude of the upstroke and MRD (maximum rate of depolarisation).

This script is written for Signal version 1.5 or later.


Waveform coherence analysis
signal\scripts\coher.sgs

This script carries out a waveform coherence analysis. There is more documentation in coher.doc, in Word format.


Capture synaptic events
eventcap6.zip 8,801

This script is designed to detect and analyse spontaneous (or miniature) synaptic events. Firstly, the script run through and detects events either via an amplitude, rate of rise or template thresholding technique. Then the user accepts or deletes the detected events. Once this is done, the user can output the amplitudes or inter-event intervals of the events and averaged events. The script also can be prompted to conduct Kolmogorov Smirnov tests on the results (or any other tables of data for that matter).

Some of these scripts have come from users rather than the CED team. If you have a script that you would like to offer to fellow users via this page, please tell Tim Bergel. We provide some scripts for Spike2 also.

These scripts are stored as WinZip files, myscript.zip, except where they are shown as signal\scripts\myscript.sgs. Those files were installed with Signal. See the summaries by clicking on the description line, below. Then you can down-load them by clicking on the filename; please check the size received.
