Averaging Example

Import stream and epoc data into Python using read_block

Plot the average waveform around the epoc event

Good for Evoked Potential detection

Note Filter

Note Filter Example

Import streaming EEG data into Python using read_block

Filter around behavioral events that were timestamped by the user using the Run-time Notes feature in Synapse, using epoc_filter

Plot each occurrence in a subplot organized by Note type

Good for sleep scoring and behavioral discrimination


Raster Peristimulus Time Histogram (PSTH) Example

Import snippet and epoc data into Python using read_block

Generate peristimulus raster and histogram plots over all trials

Good for stim-response experiments, such as optogenetic or electrical stimulation


Stream Plot Example

Import continuous data into Python using read_block

Plot a single channel of data with various filtering schemes

Good for first-pass visualization of streamed data

TDT Community Examples

We think that cultivating a strong and open community of TDT users is essential for maximizing research efficiency. The cross-pollination of ideas and methods across labs, especially those with similar research interests and using the same equipment, makes the science more rigorous overall. As such, we would like YOU to consider contributing to the TDT community with an example analysis and workbook, like the ones at the top of this page.

You can submit your examples to TDT by emailing Include your name, lab information, research interests, Python script, and a link to the block of data used in the analysis. Accepted submissions will be featured on this webpage, along with a description of the analysis and a bio of the submitting researcher. We hope that this exposure will help our users learn more about what great research others in the TDT community are doing!

Please note that, as with all our example workbooks, these workbooks represent one way of processing data. Moreover, the goal is really to show users how they might implement certain techniques on their data. These examples should not represent complete pipelines for your data analysis, and critical thought about which processing techniques and statistical analyses are most appropriate for your data set should be taken.


Fiber Photometry Epoch Averaging Example

This example goes through fiber photometry analysis using techniques
such as data smoothing, bleach detrending, and z-score analysis.
The epoch averaging was done using epoc_filter.

Author Contributions:
TDT, David Root, and the Morales Lab contributed to the writing and/or conceptualization of the code.
The signal processing pipeline was inspired by the workflow developed by David Barker et al. (2017) for the Morales Lab.
The data used in the example were provided by David Root.

About the authors:
The Root lab and Morales lab investigate the neurobiology of reward, aversion, addiction, and depression.

TDT edits all user submissions in coordination with the contributing author(s) prior to publishing.


Licking Bout Epoc Filtering

This example looks at fiber photometry data in the VTA where subjects are provided sucrose water after a fasting period. Lick events are captured as TTL pulses. Objective is to combine many consecutive licking events into a single event based on time difference and lick count thresholds. New lick bout events can then be used for clear peri-event filtering.
