| % EVALCELLTRACINGS is a graphical exploratory tool to evaluate % all or a subset of recordings or simulations of neuronal cell % membrane voltages. % % EVALCELLTRACINGS performs any combination of four displays upon % one or two files of data containing columnwise cell Vm data. % % A single filename is specified as the first argument within % single quotes, optionally contained within {curly braces}. % Dual filenames must be entered quoted within {curly braces}. % FILETYPES: % Suffix '.txt', eg 'file1.txt', will force EVALCELLTRACINGS to read % ascii data (columns corresponding to cells, rows to voltage). % Entering just the prefix, eg 'file1' will cause EVALCELLTRACINGS % to search in sequence for 'file1.mat' [more efficient loading if data % was saved as .mat], then as ascii with names 'file1' or 'file.txt'. % It is recommend to use just the 'file1' name convention, because % EVALCELLTRACINGS will then automatically create 'file1.mat' for % possible future reloading, without needing to change command line % script arguments. % % All other arguments are optional. If only the filename(s) are % provided, a 25% sample of raw cell tracings is displayed. % % Here are the four types of displays: % (see below for parameter options for each of these display types) % % RAWTRACINGS Just what it says. If 2 files are provided, % the window will be split vertically and color-coded. % % AVERAGING Plot of 100 msec-window moving average firing rate % across all spiking cells. If 2 files are provided, % the window will be split vertically and color-coded. % % WINDOWING For several time windows, show fraction of cells % firing (each window shifted a tick at a time). % % STROBE For several randomly selected cells, plots markers % for a sample of other cells with coincident firing. % For 2 files, splits figure vertically showing same cell % pairs for each file. % % PHASE For 3 randomly selected pairs of cells, plots subthreshold % membrane voltage of one cell on x-axis and the other on y-axis. % x=y diagooal line indicates similar tracings; parallel indicates % correlated activation. Spacing of dots indicates rate of % movement between phase points. Coloration indicates whether % both cells are below Vrest (black), only one is below Vrest % (blue), both are between Vrest and threshold (green). Red % asterix at border indicate phase location at onset of a spike. |
