Cell Explorer is a graphical user interface (GUI), standardized pipeline and data structure for exploring and classifying spike sorted single units acquired using extracellular electrodes.
The large diversity of cell-types of the brain provide the means by which circuits perform complex operations. Understanding such diversity is one of the key challenges of modern neuroscience. These cells have many unique electrophysiological and behavioral features from which parallel cell-type classification can be inferred. The Cell Explorer is a framework for analyzing and characterizing single cells recorded using extracellular electrodes. A high dimensional representation is built from electrophysiological and functional features including the spike waveform, spiking statistics, behavioral spiking dynamics, spatial firing maps and various brain rhythms. Moreover, we are incorporating opto-tagged cells into this pipeline (ground-truth cell types). The user-friendly graphical interface allows for verification, classification and exploration of those same features. The framework is built entirely in Matlab making it fast and intuitive to implement your own code and incorporate the Cell Explorer in your overall pipeline and analysis scripts.
The Cell Explorer can be separated into four components:
- Getting started
- Reporting bugs, enhancements or questions
- Citing the Cell Explorer in your research and publications
- Clone, fork, or download the repository (cloning is recommended).
- Add the local repository to your Matlab setpath.
- The pipeline uses
CCGHeart.c. to calculate the CCGs. Compiled versions are included for Windows and Mac. If you are using Linux you have to compile the script. In Matlab, go to
Cell-Explorer/calc_CellMetrics/CCG/and run this line:
mex -O CCGHeart.c
- The Cell Explorer GUI and pipeline uses a few toolboxes, of which three Matlab toolboxes must be installed manually.
- That’s it! Now you can explore the software with below example data or try one of the tutorials.
There is an example dataset included in the repository for trying the Cell Explorer. Load the mat-file
cell_metrics_batch.mat into Matlab and type:
We have created a few tutorials to get you started, covering the pipeline and the graphical interface. There is also a tutorial script:
CellExplorer_Tutorial.m included with example code for running the pipeline and the GUI on your data.
Please use the GitHub issues system for reporting bugs, enhancement requests or geneal questions.
