CIAtah

Maintenance GitHub release (latest by date) GitHub top language GitHub license GitHub code size in bytes visitors


CIAtah (pronounced cheetah; formerly calciumImagingAnalysis [ciapkg]) is a software package for analyzing one- and two-photon calcium imaging datasets.

ciatah_logo

CIAtah currently requires MATLAB and runs on all major operating systems (Windows, Linux [e.g. Ubuntu], and macOS).

  • Note: CIAtah version v4 moves the remaining (i.e. all except external packages/software) CIAtah functions into the ciapkg package to improve namespace handling and requires MATLAB R2019b or above (due to package import changes). Users with earlier versions of MATLAB can download CIAtah version v3 (see Releases) until pre-R2019b MATLAB support is fully integrated into v4.

Full documentation at https://bahanonu.github.io/ciatah/.

Below are recordings and additional documents for users who want to learn more about calcium imaging analysis/experiments and the CIAtah pipeline.

CIAtah features

  • CIAtah package-enclosed functions (in +ciapkg folders) can be used to create GUI-less, command line-ready analysis pipelines. As all functions are within the ciapkg package for improve namespace handling to allow incorporating into other programs.
  • A GUI, via ciatah class, with different modules for large-scale batch analysis.
  • Includes all major calcium imaging analysis steps:
    • Movie visualization (including reading from disk, for fast viewing of large movies);
    • pre-processing (motion correction, spatiotemporal downsampling, spatial filtering, relative fluorescence calculation, etc.);
    • support for multiple cell-extraction methods (CELLMax, PCA-ICA, CNMF, CNMF-E, EXTRACT, etc.);
    • manual classification of cells via GUIs;
    • automated cell classification (i.e. CLEAN algorithm, coming soon!);
    • cross-session cell alignment, and more.
  • Includes example one- and two-photon calcium imaging datasets for testing CIAtah.
  • Supports a plethora of major imaging movie file formats: HDF5, NWB, AVI, ISXD [Inscopix], TIFF, and Bio-Formats compatible formats (Olympus [OIR] and Zeiss [CZI and LSM] currently, additional support to be added or upon request).
  • Supports Neurodata Without Borders data standard (see calcium imaging tutorial) for reading/writing cell-extraction and imaging movie files.
  • Animal position tracking (e.g. in open-field assay) via ImageJ plugin.
  • Requires MATLAB and runs on all major operating systems (Windows, Linux [e.g. Ubuntu], and macOS).

Quick start guide

Below are steps needed to quickly get started using the CIAtah software package in MATLAB.

Download and install CIAtah

  • Clone the CIAtah repository (using GitHub desktop or command line) or download the repository zip and unzip (e.g. run below MATLAB command).
% Optional: this will set MATLAB working folder to the default user path. Make sure you have read/write permissions.
try; cd(userpath); catch; end;

% Download and unzip current repository
unzip('https://github.com/bahanonu/ciatah/archive/master.zip');

% Make CIAtah the working folder
cd('ciatah-master')

Check required toolboxes are installed

CIAtah depends on several MATLAB toolboxes to run properly. Run the below command to have CIAtah check whether dependencies have been installed properly. If not use the Add-Ons (https://www.mathworks.com/help/matlab/matlab_env/get-add-ons.html) explorer to install each toolbox.

ciapkg.io.matlabToolboxCheck();

Setup CIAtah

  • Run CIAtah using the below MATLAB commands. Call obj; in the MATLAB command window each time you want to go back to the main GUI. Note: calciumImagingAnalysis class is now called ciatah, all functionality is the same.
% Loads the class into an object for use in this session
obj = ciatah();

% Runs routines to check dependencies and help user get setup.
obj.setup();

% Open the class menu (always type `obj` then enter load the class/modules menu)
obj % then hit enter, no semicolon!
  • Afterwards, run the modelAddNewFolders module to add data folders the current CIAtah class object.
  • Run obj; in the command window to see the main GUI.
  • Full documentation at https://bahanonu.github.io/ciatah/.
  • [Optional] Users on Windows systems can download Everything (https://www.voidtools.com/). It is a very useful and extremely fast search engine for files and folders that allows users to quickly obtain lists of full folder paths for analysis in CIAtah.
  • [Optional] If run into issues opening certain AVI files (e.g. due to codec issues) with CIAtah/MATLAB, install K-Lite Codec Pack (https://codecguide.com/download_kl.htm) or similar for added support.

Visualize movies quickly using read from disk

Users can quickly visualize movies in any of the supported formats (HDF5, NWB, AVI, TIFF, and ISXD) using the playMovie function. This will read directly from disk, allowing users to scroll through frames to visually check movies before or after processing.

Users can run via the command-line:

% Use the absolute path to the movie file or a valid relative path.
ciapkg.api.playMovie('ABSOLUTE\PATH\TO\MOVIE');

When using HDF5 files, check the dataset name containing movie with h5disp then input the full dataset name (e.g. below is for a standard NWB-formatted HDF5 file):

ciapkg.api.playMovie('ABSOLUTE\PATH\TO\MOVIE','inputDatasetName','/acquisition/TwoPhotonSeries/data');

Alternatively, using the ciatah GUI class, users can select loaded folders and change the regular expression to match the name of the files in the movie, both for the raw data and for any processed movies in the folder. See below:

ciapkgMovie

Quick start (command line or GUI-less batch analysis)

After downloading CIAtah and running the setup as above, users interested in command-line processing can open up the example M-file by running the below command. By running individual code-block cells, users are guided from pre-processing through cell-extraction to cross-session analysis.

edit ciapkg.demo.cmdLinePipeline

Users can import the CIAtah ciapkg that contains the command-line functions using the below command at the beginning of their functions. This will import all ciapkg functions into the functions workspace such that ciapkg.api.loadMovieList() (an alias for ciapkg.io.loadMovieList()) can be called as loadMovieList().

import ciapkg.api.* % import CIAtah functions in ciapkg package API.
