CoherenceAnalyzer¶
Bases: NitimeBaseInterface
Wraps nitime.analysis.CoherenceAnalyzer: Coherence/y
- NFFT : a long 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)- TR : a 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_range : a 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_TS : any value
- A nitime TimeSeries object.
- in_file : a 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_overlap : a long integer >= 0
- The number of samples which overlapbetween subsequent windows.(Defaults to 0). (Nipype default value:
0)- output_csv_file : a pathlike object or string representing a file
- File to write outputs (coherence,time-delay) with file-names:
file_name_{coherence,timedelay}.- output_figure_file : a 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_array : an array
- The pairwise coherence values between the ROIs.
- coherence_csv : a pathlike object or string representing a file
- A csv file containing the pairwise coherence values.
- coherence_fig : a pathlike object or string representing a file
- Figure representing coherence values.
- timedelay_array : an array
- The pairwise time delays between the ROIs (in seconds).
- timedelay_csv : a pathlike object or string representing a file
- A csv file containing the pairwise time delay values.
- timedelay_fig : a pathlike object or string representing a file
- Figure representing coherence values.
