Read Binary Files Saved by 'Igor Pro' (Including 'Neuromatic' Data)

Provides function to read data from the 'Igor Pro' data analysis program by Wavemetrics. The data formats supported are 'Igor' packed experiment format (pxp) and 'Igor' binary wave (ibw). See: http://www.wavemetrics.com/ for details. Also includes functions to load special pxp files produced by the 'Igor Pro' 'Neuromatic' and 'Nclamp' packages for recording and analysing neuronal data. See http://www.neuromatic.thinkrandom.com/ for details.


DOI Release Version CRAN_Status_Badge Build Status The IgorR package for R provides routines to read binary files generated by Igor Pro.

This includes both the standalone .ibw Igor Binary Wave format (v2 and the latest v5) and the .pxp Packed Experiment Format including both waves and variables. In addition the package provides functions to read files generated by the Neuromatic analysis suite written by Jason Rothman for Igor Pro.
