Please note that WaveSurfer is currently pre-release software. There will almost certainly be changes to file formats, etc. before version 1.0 is released (in 2018), and we make no promises about backward compatibility.
Version 0.913 and earlier have a bug where they don't record the ADC calibration data from the NI board, leading to 5-7% errors in the signals when read back in with ws.loadDataFile(). Because of this, these versions should not be used, and we no longer make them available here. If you have data files recorded with one of these versions, download the latest version of WaveSurfer and use the ws.addScalingToHDF5FilesRecursively() tool to read the calibration data off your board and append it to your data files.

The coordination between WaveSurfer and ScanImage has changed in recent versions, and this is not reflected in the most recent WaveSurfer manual available. The new capabilities are described here.

WaveSurfer is developed at the HHMI Janelia Research Campus. It has been supported by the Svoboda Lab, who initiated the project, and by the Magee, Spruston, Jayaraman, Lee, Hantman, and Koyama Labs. The project is coordinated by Janelia's Scientific Computing Software group.
WaveSurfer supplants an earlier application, Ephus, for electrophysiology and similar data-acquisition tasks. WaveSurfer is a from-scratch rewrite of Ephus developed by Janelia's Scientific Computing group, and shares no code with Ephus. Vijay Iyer specified the original design and is the primary author of the Dabs and Most library packages. Patrick Edson was a co-developer of the earliest versions of WaveSurfer. WaveSurfer borrows design features from DataPro, an electrophysiological acquisition and analysis system for Wavemetrics Igor Pro, originally written by Nelson Spruston and later rewritten by Adam L. Taylor .
