Wraps nitime.analysis.CoherenceAnalyzer: Coherence/y
- NFFTa 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
)- 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_overlapa long 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.
