qetpy.io.io.loadstanfordfile(f, convtoamps=1024, lgcfullrtn=False)¶

Function that opens a Stanford .mat file and extracts the useful parameters. There is an option to return a dictionary that includes all of the data.

Parameters:

f : list, str: A list of filenames that should be opened (or just one filename). These files should be Stanford DAQ .mat files.
convtoamps : float, optional: Correction factor to convert the data to Amps. The traces are divided by this factor, as is the TTL channel (if it exists). Default is 1024.
lgcfullrtn : bool, optional: Boolean flag that also returns a dict of all extracted data from the file(s). Set to False by default.

Returns:

traces : ndarray: An array of shape (# of traces, # of channels, # of bins) that contains the traces extracted from the .mat file.
times : ndarray: An array of shape (# of traces,) that contains the starting time (in s) for each trace in the traces array. The zero point of the times is arbitrary.
fs : float: The digitization rate (in Hz) of the data.
ttl : ndarray, None: The TTL channel data, if it exists in the inputted data. This is set to None if there is no TTL data.
data : dict, optional: The dictionary of all of the data in the data file(s). Only returned if lgcfullrtn is set to True.

qetpy.io.io.getchannels_singlefile(filename)¶

Function for opening a .mat file from the Stanford DAQ and returns a dictionary that contains the data.

Parameters:	filename : str The filename that will be opened. Should be a Stanford DAQ .mat file.
Returns:	res : dict A dictionary that has all of the needed data taken from a Stanford DAQ .mat file.

qetpy.io.io.getchannels(filelist)¶

Function for opening multiple .mat files from the Stanford DAQ and returns a dictionary that contains the data.

Parameters:	filelist : list, str The list of files that will be opened. Should be Stanford DAQ .mat files.
Returns:	combined : dict A dictionary that has all of the needed data taken from all of the inputted Stanford DAQ .mat files.
