What is it?
A general-purpose signal analysis package aimed particularly at those in biology, electrophysiology and neuroscience
If you want simply to analyse your data:
sigTOOL provides an intuitive graphical-user interface based program for analysing waveforms and spike-trains. This provides menu-driven analysis, plotting and data export facilities using the underlying sigTOOL environment.
If you are a code developer:
sigTOOL is a code development environment that is built on top of MATLAB to help with writing custom software in signal analysis. You get the full facilities and power of the MATLAB environment together with the convenience of easy-to-use data access, plotting and export functions via sigTOOL. Essentially, sigTOOL let’s you write and re-distribute original code without re-inventing the wheel. Code developed with sigTOOL will automatically slot into the GUI and can be zipped, redistributed and used in any lab using a sigTOOL-supported file format.
Supported formats presently include:
ABF............... pClamp, AxoScope etc
CFS............... CED Signal
DAT............... HEKA Patchmaster etc
MAP............... Alpha Omega
MCD............... MultiChannel Systems
NEX............... Nex technologies
NEV............... Blackrock Systems (Cyberkinetics)
NSN............... Neuroshare Native
PLX............... Plexon
SMR............... CED Spike2
SSD/STAT.......... DC Progs (UCL)
STAM.............. STA Toolkit (Weill)
as well as multi-media formats (wav, mp3 etc).
