These files enable LabVIEW users to interface to the CED 1401 via the CED Windows Library: USE1432.DLL. They provide function calls listed in the CED Programmer's Interface Library for Windows as LabVIEW vi's in 1401.llb, together with LabVIEW test programmes in Test1401.llb and Word documentation in Lv1432.doc. The functions are written for Windows 95/98 and NT.

This is a suite of VIs for controlling the 1902 amplifier from National Instruments LabVIEW.
The VIs are for LabVIEW 6.1 and will not run under lower versions of LabVIEW.
Documentation in ASCII text is included in the 1902.zip file.
Download the documentation text file (2 k) or a zipfile archive (210 k) containing the Labview library and documentation.

"Matced" is an interface that allows Matlab to directly control the CED 1401 data acquisition system. This allows one to have a powerful front-end computing environment to process and plot data sampled by the CED. At the same time one can program the CED-1401 using Matlab's M-files. Together with Matlab's graphical user interface (uicontrol) one can easily build a complete windows application using M-files.

32 bit version
Jim Colebatch has kindly converted the work above to a 32 bit version needed for modern versions of Matlab. Down-load matced32.zip 28,372 bytes, which WinZip will expand to give you matced32.c, matced32.dll, matced32.m and mat1401X.m and mat1301Xp.m - the last two are example code which are simple example programs. In the latest revision, he says:
The DLL includes the option of a call to U14WorkingSet, and subroutines with errors now always return the error code.
Jim has also provided a Matlab GUI to use the 1401, matgui.zip, 47,426 bytes. It works with version 6.5.1, 7.0 and 7.1 (at least) and allows simple data collection directly into Matlab. It uses his MATCED32.DLL, above.
The code illustrates a number of features of the Matlab GUI, in particular how variables are saved and can be passed between windows.
Down-load MATLAB SON Library as part of sigTOOL, which contains routines for loading/writing/creating Spike2 for Windows files in MATLAB, from http://sigtool.sourceforge.net.

Down-load the MATLAB CFS Library zip (37,418), which contains routines for loading/writing/creating Signal files in MATLAB.
Jim has tested these files with Matlab 6.5.1 and several versions of Matlab 7 - up to R2007a (Matlab 7.5). All seems to work OK. The support files describe how to use the calls and give several example m files. They are all in the zip file, updated 4 February 2010.

sigTOOL provides a programming and analysis environment for processing neuroscience data. A graphical-user interface to this environment provides the end-user with a self-contained application for waveform and spike-train analysis. User-written extensions to this application can be added to the interface on-the-fly without the need to modify any of the existing code. Spike2 and Signal file formats are included in the import selection. Click here to read more.

The program CFS2EXCEL is intended to convert CFS data files, typically from SIGAVG or CHART, into a form suitable for import into Excel. It only works with CFS files which are equally spaced integer data - such as standard SIGAVG files.

The Strathclyde Electrophysiology Software is NOT contributed software to this site, but it is a very widely used suite of programs for recording and analysing signals from intracellular electrophysiology experiments, that can run with members of the CED 1401 family.
Gary Bhumbra writes: We have written version 2 of interLab: Like the original interLab, it allows spontaneous spike activity to be analysed using information theory applied to the log joint interval histogram. I was asked by many users to extend the program so it can look at stimulus-evoked activity. Consequently I rewrote interLab2 from the ground-up to improve the graphical user interface and file import/export, and I have included automated analysis of the phase interval stimulus histogram to quantify the strength of stimulus-evoked responses using information theory
It reads Spike 2 file channels (at least up to version 4) calling functions written by Malcolm Liddierth (who we acknowledge and whose functions are already available here). Our package can be accessed from a link to our ftp via: www.pdn.cam.ac.uk/staff/dyball/interlab.html.

LabSpike is spike discriminator that combines different methods of discrimination. It can read Spike2 files (we've tested up to version 4.0) and outputs to a binary or text file, which can be imported directly back into a Spike2 file, with Spike2 versions 4 and onwards.
Like Spike 2 version 5, it features PCA, but also incorporates other aspects of shape such as the FFT. There are a lot of other features to assist discrimination, including a GUI that is devoted to what's suited to discrimination.
This is an alpha version, as it's a prototype program. We haven't written a manual, help pages, or tooltips but with a bit of experimentation (and use of the right-click!), it should be straightforward to see what does what. The file is available from the webpage:
http://www.pdn.cam.ac.uk/staff/dyball/labspike.html
Details of methods are available in: G.S. Bhumbra, A.N. Inyushkin, and R.E.J. Dyball (2004): `Assessment of spike activity in the supraoptic nucleus. Review.' J. Neuroendocrinol. 16:390-397. Any bug reports, comments, or suggestions are warmly welcome.

SON LIBRARY for PYTHON (20,394 bytes)
For reading data from CED's Spike2 Son files.
Based on SON Library 2.0 for MATLAB, written by Malcolm Lidierth at King's College London. See http://www.kcl.ac.uk/schools/biohealth/depts/physiology/mlidierth.html
Using the library
For details read the file __init__.py, or type the following in a Python shell (after placing the sonpy directory in your Python search path):
>>> from sonpy import son
>>> help(son)
