A simple loader for Spike2 files (.smrx). Note that this package uses the sonpy package provided by spike2 which requires python 3.9.
It provides one executable named smrx2python that directly operates on files and a function named as_python_data to load an smrx file as a pandas table and numpy arrays.
The usage is the following:
smrx2python -i MYFILE.smrx, where MYFILE.smrx is the path to your spike2 file.
It will create a tsv file MYFILE.tsv and a folder named MYFILE_data in the same folder as MYFILE.smrx. The contents are:
- MYFILE.tsv contains metadata for each channel
- MYFILE_data contains an
.npyfile (numpy array) for each channel.- For event channels, the contents of the array are the timing of the events in seconds. Note if the channel is registered as a rise and fall event (EventBoth on spike2), then the array will have two columns, one for rise and one for fall.
- For continuous channels the arrays are simply the set of values at the given sampling frequency (given by fs (in Hertz) from MYFILE.tsv)
Similar to smrx2python -i MYFILE.smrx but returns the pandas dataframe and a dictionary of numpy array instead of files.
