Link to code

> Bases: NitimeBaseInterface

> Wraps nitime.analysis.CoherenceAnalyzer: Coherence/y

> NFFTan integer >= 32

>   This is the size of the window used for the spectral estimation. Use values between 32 and the number of samples in your time-series.(Defaults to 64.). (Nipype default value: `64`)

> TRa float

>   The TR used to collect the data in your csv file <in_file>.

> figure_type‘matrix’ or ‘network’

>   The type of plot to generate, where ‘matrix’ denotes a matrix image and’network’ denotes a graph representation. Default: ‘matrix’. (Nipype default value: `matrix`)

> frequency_rangea list of from 2 to 2 items which are any value

>   The range of frequencies overwhich the analysis will average.[low,high] (Default [0.02,0.15]. (Nipype default value: `[0.02, 0.15]`)

> in_TSany value

>   A nitime TimeSeries object.

> in_filea pathlike object or string representing an existing file

>   Csv file with ROIs on the columns and time-points on the rows. ROI names at the top row. Requires inputs: `TR`.

> n_overlapan integer >= 0

>   The number of samples which overlapbetween subsequent windows.(Defaults to 0). (Nipype default value: `0`)

> output_csv_filea pathlike object or string representing a file

>   File to write outputs (coherence,time-delay) with file-names: `file_name_{coherence,timedelay}`.

> output_figure_filea pathlike object or string representing a file

>   File to write output figures (coherence,time-delay) with file-names: `file_name_{coherence,timedelay}`. Possible formats: .png,.svg,.pdf,.jpg,…

> coherence_arrayan array

>   The pairwise coherence values between the ROIs.

> coherence_csva pathlike object or string representing a file

>   A csv file containing the pairwise coherence values.

> coherence_figa pathlike object or string representing a file

>   Figure representing coherence values.

> timedelay_arrayan array

>   The pairwise time delays between the ROIs (in seconds).

> timedelay_csva pathlike object or string representing a file

>   A csv file containing the pairwise time delay values.

> timedelay_figa pathlike object or string representing a file

>   Figure representing coherence values.
