add_cell_specimen_table
(nwbfile: pynwb.file.NWBFile, cell_specimen_table: pandas.core.frame.DataFrame, session_metadata: dict)[source]¶ This function takes the cell specimen table and writes the ROIs contained within. It writes these to a new NWB imaging plane based off the previously supplied metadata
Parameters: - nwbfile: NWBFile
this is the in memory NWBFile currently being written to which ROI data is added
- cell_specimen_table: pd.DataFrame
this is the DataFrame containing the cells segmented from a ophys experiment, stored in json file and loaded. example: /home/nicholasc/projects/allensdk/allensdk/test/
brain_observatory/behavior/cell_specimen_table_789359614.json
- session_metadata: dict
Dictionary containing cell_specimen_table related metadata. Should include at minimum the following fields:
“emission_lambda”, “excitation_lambda”, “indicator”, “targeted_structure”, and ophys_frame_rate”
Returns: - nwbfile: NWBFile
The altered in memory NWBFile object that now has a specimen table
