How to reproduce the results/figures from the publication

Setup

• Setup the Python environment (conda env create -f environment.yaml) and activate it.
• Setup Cobrawap with cobrawap init and follow the instructions to
  • set the cobrawap output path (<cobrawap_output>),
  • set the cobrawap config path (<cobrawap_configs>) (see also the documentation).
• Set the local project paths in project_utils/project_paths.py.

Get the data

• Download the ECoG (IDIBAPS) and calcium imaging (LENS) datasets from the EBRAINS KnowledgeGraph:
  • IDIBAPS_WBS: doi:10.25493%2FDZWT-1T8
  • IDIBAPS_FXS: doi:10.25493/ANF9-EG3
  • IDIBAPS_PM: 10.25493/WKA8-Q4T
  • LENS_M: 10.25493/QFZK-FXS
  • LENS_ISO: 10.25493/XJR8-QCA
• Set the path parameter (DATA_SETS) in the stage01_data_entry/config/config_<profile>.yaml files to the corresponding data locations.

Run the analysis pipeline

• To produce all the possible pipeline outputs <cobrawap_output>/<profile><variant>/stage05_(channel_)wave_characterization/<event-type>_<measure-type>_measures.csv, set the event-type and measure-type accordingly and execute:

  cobrawap run --profile=<profile>
  

  Note: the folder cobrawap_output/ contains example output for the profiles IDIBAPS_WBS_WT4 and LENS_M2_t1.

Profiles: The names that are used for the individual recordings and their corresponding configurations are listed in project_utils/profiles.txt.

Variants: Variants are alternative configurations for a profile and can be specified by appending a corresponding label to the profile with a '|', e.g. <profile>|minimatrigger. Here, additional variants for spatial downsampling and alternative trigger detection are applied to all LENS datasets: |macrodim3, |macrodim5, |macrodim7, |macrodim9, |macrodim11, |minimatrigger.

Measure types: There are two alternative final stages of the pipeline stage05_wave_characterization and stage05_channel_wave_characterization, corresponding to calculating either wave-wise or channel-wise characteristic measures. You can select between them in the top-level pipeline config <cobrawap_configs>/configs/config.yaml.

Event types: The wave characterization in the pipeline output can be either given for all wavefronts or all wavemodes (wavemode = average of similar wavefronts). You can select between them by setting the parameter EVENT_NAME in the corresponding stage05 config file. Also change the prefix of the STAGE_OUTPUT accordingly as wavefronts or wavemodes.

Aggregate the output of the analysis pipeline

In the folder aggregate_pipeline_output run snakemake (snakemake -c1) to create the combined dataframes from the individual pipeline outputs:

• <event-type>_<measure-type><variant>_measures.csv containing the pipeline outputs for all profiles,
• wavefronts_<measure-type>_trend_measures.csv containing the moments of each measure for the downsampled (|macrodim) calcium imaging data,
• wavemodes_<measure-type>_avg_measures.csv containing the measures per wavefront averaged for each wavemode.

Note: the folder cobrawap_output/aggregated_output/ already contains these precomputed dataframes.

Plot the figures

In folder plot_figures:

• Run snakemake -c1 to produce Figure 5 and 6.
• Execute plot_wavemodes_dashboard.ipynb to produce Figure 4 and S3 (change profile name in notebook accordingly).
• Execute plot_trigger_detection_f-anesthesia.ipynb to produce Figure S4.
  • Note: requires running the analysis pipeline for the IDIBAPS_PM recordings, for which the pipeline output is not contained in this repository.
• Execute plot_examples_frames.ipynb to produce wave frames in Figure 2.
  • Note: to plot the ECoG waves frames data, it requires the additional pipeline run of the corresponding profile with reduced rate cobrawap run --profile=IDIBAPS_WBS_WT4|25Hz.

Note: the folder figures/ already contains these generated figures.
