Formatting your data

Input format for the code

Currently, the code only accepts plain binary data. To be more precise, suppose you have N channels

\[c_0, c_1, ... , c_N\]

And if you assume that \(c_i(t)\) is the value of channel \(c_i\) at time t, then your datafile should be a giant raw file with values

\[c_0(0), c_1(0), ... , c_N(0), c_0(1), ..., c_N(1), ... c_N(T)\]

This is simply the flatten version of your recordings matrix, with size N x T

Note

The values can be saved in your own format (int16, uint16, int8, float32). You simply need to specify that to the code

Header

Your datafile can have a header, with some information about your recordings before the raw data themselves. Quite often, this header has a variable size, so either you know it (see data_offset), either your recording has been exported from a MultiChannel Device (using MCDataTools), and therefore, by setting data_offset = MCS, the size is automatically handled. If you do not have any header, just set data_offset = 0

Note

The best way to see if your data are properly loaded is to use the preview mode of the code (see documentation on Python GUI). If you have issues, please be in touch with pierre.yger@inserm.fr

Future plans

Hopefully in a near future, we plan to enhance the interface between SpyKING CIRCUS and various file formats. Most likely using Neo, we should be able to read/write the data without a need for a proper raw file.
