spike_analysis_pipeline:intermediate_output

### Table of Contents

## Interactions with other pipelines

because spike_analysis incorporates the sorted_neurons table (f.e. unit_IDs and site_IDs) into behavior and ephys data, it is used as a first step in all ephys analysis.

Outputs in Y:\Projects\project\ephys\version:

File | Info |
---|---|

population_monkey_session.mat | spike data sorted by unit for each session |

sites_monkey_session.mat | LFP data sorted by site for each session |

by_block_monkey_session.mat | body signals sorted by block for each session |

Mon_sorted_neurons.xls | copies of the used sorted neurons tables from dropbox |

keys_Monkey.mat | copy of the keys used when running ph_initiation |

tuning_table_combined.mat | Anova results stored in a table |

tuning_table_combined_CI.mat | Anova results restructured according to contra/ipsi definitions |

tuning_table_combined.xls | simplified excel table |

spike_shapes | Spike shapes, firing rates over time, and ISI plots for re-assessing spike sorting |

The three main files come in a specific data structure, which contain the same fields except for the respective data:

- by_block(body signals) - only trial information and body signals
- sites (LFP) - additional site information and LFP, no body signals
- population (spikes) - additional unit information and spike_arrival times, no LFP, no body signals
