spikeAnalysis_utils module¶

spikeAnalysis_utils.construct_artefact_free_edf_signal(sig_dirpath, interest_csv_filepath, sep=';', out_dirpath=[])¶

From a csv file containing the periods of interest (free of artefacts), construct an EDF file without the artefact periods. The output files are then synchronized with the SpykingCircus spike times.

Parameters:

sig_dirpath : str Path of the directory containing the EDF signals interest_csv_filepath : str Path of the file containing the periofs of interest (no artefact). This file must be a 3 column csv files. 1st column contain the input EDF filename (in sig_dirpath), the 2nd column contain the starting time (s) of the artefact, the 3rd colum contain the ending time of the artefact. Each row represents 1 artefact. 1-line header. sep : str (default: ‘;’) Csv file delimiter out_dirpath : str | none (default) Path of the directory where the output files are saved

spikeAnalysis_utils.createuniquedir(dirpath)¶

Create a unique directory from a path. If …/…/dir_name already exists, …/…/dir_name_2 is returned.

Parameters:	dirpath : str Directory path
Returns:	unique_dir_path : str Unique directory path

spikeAnalysis_utils.find_original_time(x_target, filename, keep_start, keep_end)¶

From the Spyking-Circus spike time, get the original time in the original EEG file. This EEG file was first cut to remove artefacts. Start end end time of artefact-free periods are stored in arguments keep_start and keep_end. Multiples files may have been used to do the spike-sorting, thus filename contains the filename for each artefact-free period.

Parameters:	x_target : float Time of the Spyking-Circus spike filename : array Filename for each artefact-free period keep_start : array Start time (s) of each artefact-free period keep_end : array End time (s) of each artefact-free period
Returns:	y_ori : float Time of the spike in the original EEG file filename_i : str Name of the file containing the spike
