gphys-package.Rdgphys = Greg's ephys (and perhaps gee whiz)
You can use functions such as
PlotRasterFromSweeps to view spike data. This function and others
depend on spike times stored in Igor Pro text files. For details of how to make
these files in Igor see:
http://flybrain.mrc-lmb.cam.ac.uk/dokuwiki/doku.php?id=protocols:analysing_spikes
Spike times read in from Igor Pro text files by CollectSpikesFromSweeps
are stored in R a modified list of S3 class spiketimes.
You can add, subset and split these lists - see spiketimes
and links therein for details.
You can also add continuous traces such as membrane voltage, PID signals etc
to your raster plots. See AddLinesToRasterPlot.
If you have a mistake in the assignments of your ODD channels (e.g. you were
opening channel 27 when you thought you were opening 29) you will likely need
to use the function fix.odd to make the correct assignments. If
you simply want to relabel a channel you can use the relabelfun
argument of PlotRasterFromSweeps - see function documentation for
examples.
Note that you may find it useful to set e.g.
options(gphys.datadir='/Volumes/JData/JPeople/Jonny/physiology/data')
appropriately at the start of a session or in your
.Rprofile file. You can then use relative paths to
your Igor data folders in the plot functions.
Finally as.repeatedTrain provides a bridge to the STAR
package which includes many spike analysis functions including (smoothed)
peristimulus time histograms.
options, spiketimes, PlotRasterFromSweeps,
CollectSpikesFromSweeps
and STAR package for further analysis.
