mne.Report¶

class mne.Report(info_fname=None, subjects_dir=None, subject=None, title=None, cov_fname=None, baseline=None, image_format='png', raw_psd=False, projs=False, verbose=None)[source]¶

Object for rendering HTML.

Parameters

info_fnameNone | str

Name of the file containing the info dictionary.

subjects_dirstr | None

The path to the FreeSurfer subjects reconstructions. It corresponds to FreeSurfer environment variable SUBJECTS_DIR.

subjectstr | None

Subject name.

titlestr

Title of the report.

cov_fnameNone | str

Name of the file containing the noise covariance.

baselineNone | tuple of length 2

The time interval to consider as “baseline” when applying baseline correction. If None, do not apply baseline correction. If a tuple (a, b), the interval is between a and b (in seconds), including the endpoints. If a is None, the beginning of the data is used; and if b is None, it is set to the end of the interval. If (None, None), the entire time interval is used.

Note

The baseline (a, b) includes both endpoints, i.e. all timepoints t such that a <= t <= b.

Correction is applied in the following way to each channel:

Calculate the mean signal of the baseline period.
Subtract this mean from the entire time period.

For Epochs, this algorithm is run on each epoch individually. Defaults to None, i.e. no baseline correction.

image_formatstr

Default image format to use (default is ‘png’). SVG uses vector graphics, so fidelity is higher but can increase file size and browser image rendering time as well.

New in version 0.15.

raw_psdbool | dict

If True, include PSD plots for raw files. Can be False (default) to omit, True to plot, or a dict to pass as kwargs to mne.io.Raw.plot_psd().

New in version 0.17.

projsbool

Whether to include topographic plots of SSP projectors, if present in the data. Defaults to False.

New in version 0.21.

verbosebool, str, int, or None

If not None, override default verbose level (see mne.verbose() and Logging documentation for more). If used, it should be passed as a keyword-argument only.

Notes

See Getting started with mne.Report for an introduction to using mne.Report, and this example for an example of customizing the report with a slider.

__len__()[source]¶: Return the number of items in report.

add_bem_to_section(subject, caption='BEM', section='bem', decim=2, n_jobs=1, subjects_dir=None, replace=False)[source]¶

Render a bem slider html str.

Parameters

subjectstr: Subject name.
captionstr: A caption for the bem.
sectionstr: Name of the section. If section already exists, the bem will be appended to the end of the section.
decimint: Use this decimation factor for generating MRI/BEM images (since it can be time consuming).
n_jobsint: The number of jobs to run in parallel (default 1). Requires the joblib package.
subjects_dirstr | None: The path to the FreeSurfer subjects reconstructions. It corresponds to FreeSurfer environment variable SUBJECTS_DIR.
replacebool: If True, figures already present that have the same caption will be replaced. Defaults to False.

Notes

New in version 0.9.0.

add_figs_to_section(figs, captions, section='custom', scale=None, image_format=None, comments=None, replace=False)[source]¶

Append custom user-defined figures.

Parameters

figsmatplotlib.figure.Figure | mlab.Figure | array | list: A figure or a list of figures to add to the report. Each figure in the list can be an instance of matplotlib.figure.Figure, mayavi.core.api.Scene, or numpy.ndarray.
captionsstr | list of str: A caption or a list of captions to the figures.
sectionstr: Name of the section to place the figure in. If section already exists, the figures will be appended to the end of the section.
scalefloat | None | callable(): Scale the images maintaining the aspect ratio. If None, no scaling is applied. If float, scale will determine the relative scaling (might not work for scale <= 1 depending on font sizes). If function, should take a figure object as input parameter. Defaults to None.
image_formatstr | None: The image format to be used for the report, can be ‘png’ or ‘svd’. None (default) will use the default specified during Report class construction.
commentsNone | str | list of str: A string of text or a list of strings of text to be appended after the figure.

Examples using add_figs_to_section:

add_htmls_to_section(htmls, captions, section='custom', replace=False)[source]¶

Append htmls to the report.

Parameters

htmlsstr | list of str: An html str or a list of html str.

Examples using parse_folder:

remove(caption, section=None)[source]¶

Remove a figure from the report.

The figure to remove is searched for by its caption. When searching by caption, the section label can be specified as well to narrow down the search. If multiple figures match the search criteria, the last one will be removed.

Any empty sections will be removed as well.

Parameters

captionstr: If set, search for the figure by caption.
sectionstr | None: If set, limit the search to the section with the given label.

Returns

removed_indexint | None: The integer index of the figure that was removed, or None if no figure matched the search criteria.

save(fname=None, open_browser=True, overwrite=False)[source]¶

Save the report and optionally open it in browser.

Parameters

fnamestr | None: File name of the report. If the file name ends in ‘.h5’ or ‘.hdf5’, the report is saved in HDF5 format, so it can later be loaded again with open_report(). If the file name ends in anything else, the report is rendered to HTML. If None, the report is saved to ‘report.html’ in the current working directory. Defaults to None.
open_browserbool: When saving to HTML, open the rendered HTML file browser after saving if True. Defaults to True.
overwritebool: If True, overwrite report if it already exists. Defaults to False.

Returns
