Overlaid on top of the co-registration results, the displacements along the phase-encoding direction are represented in arbitrary units. Please note that the color scale is centered around zero (i.e. full transparency), but the extremes might be different (i.e., the maximum of red colors could be orders of magnitude above or below the minimum of blue colors.) static: false subtitle: Estimated fieldmap and alignment to the corresponding EPI reference - bids: {datatype: figures, desc: sdc, suffix: bold} caption: Results of performing susceptibility distortion correction (SDC) on the EPI static: false subtitle: Susceptibility distortion correction - bids: {datatype: figures, desc: forcedsyn, suffix: bold} caption: The dataset contained some fieldmap information, but the argument --force-syn was used. The higher-priority SDC method was used. Here, we show the results of performing SyN-based SDC on the EPI for comparison. static: false subtitle: Experimental fieldmap-less susceptibility distortion correction - bids: {datatype: figures, desc: flirtnobbr, suffix: bold} caption: FSL flirt was used to generate transformations from EPI space to T1 Space - BBR refinement rejected. Note that Nearest Neighbor interpolation is used in the reportlets in order to highlight potential spin-history and other artifacts, whereas final images are resampled using Lanczos interpolation. static: false subtitle: Alignment of functional and anatomical MRI data (volume based) - bids: {datatype: figures, desc: coreg, suffix: bold} caption: mri_coreg (FreeSurfer) was used to generate transformations from EPI space to T1 Space - bbregister refinement rejected. Note that Nearest Neighbor interpolation is used in the reportlets in order to highlight potential spin-history and other artifacts, whereas final images are resampled using Lanczos interpolation. static: false subtitle: Alignment of functional and anatomical MRI data (volume based) - bids: {datatype: figures, desc: flirtbbr, suffix: bold} caption: FSL flirt was used to generate transformations from EPI-space to T1w-space - The white matter mask calculated with FSL fast (brain tissue segmentation) was used for BBR. Note that Nearest Neighbor interpolation is used in the reportlets in order to highlight potential spin-history and other artifacts, whereas final images are resampled using Lanczos interpolation. static: false subtitle: Alignment of functional and anatomical MRI data (surface driven) - bids: {datatype: figures, desc: bbregister, suffix: bold} caption: bbregister was used to generate transformations from EPI-space to T1w-space. Note that Nearest Neighbor interpolation is used in the reportlets in order to highlight potential spin-history and other artifacts, whereas final images are resampled using Lanczos interpolation. static: false subtitle: Alignment of functional and anatomical MRI data (surface driven) - bids: {datatype: figures, desc: rois, suffix: bold} caption: Brain mask calculated on the BOLD signal (red contour), along with the masks used for a/tCompCor.
The aCompCor mask (magenta contour) is a conservative CSF and white-matter mask for extracting physiological and movement confounds.
The fCompCor mask (blue contour) contains the top 5% most variable voxels within a heavily-eroded brain-mask. subtitle: Brain mask and (temporal/anatomical) CompCor ROIs - bids: datatype: figures desc: '[at]compcor' extension: [.html] suffix: bold - bids: {datatype: figures, desc: 'compcorvar', suffix: bold} caption: The cumulative variance explained by the first k components of the t/aCompCor decomposition, plotted for all values of k. The number of components that must be included in the model in order to explain some fraction of variance in the decomposition mask can be used as a feature selection criterion for confound regression. subtitle: Variance explained by t/aCompCor components - bids: {datatype: figures, desc: carpetplot, suffix: bold} caption: Summary statistics are plotted, which may reveal trends or artifacts in the BOLD data. Global signals calculated within the whole-brain (GS), within the white-matter (WM) and within cerebro-spinal fluid (CSF) show the mean BOLD signal in their corresponding masks. DVARS and FD show the standardized DVARS and framewise-displacement measures for each time point.
A carpet plot shows the time series for all voxels within the brain mask, or if ``--cifti-output`` was enabled, all grayordinates. Voxels are grouped into cortical (dark/light blue), and subcortical (orange) gray matter, cerebellum (green) and white matter and CSF (red), indicated by the color map on the left-hand side. subtitle: BOLD Summary - bids: {datatype: figures, desc: 'confoundcorr', suffix: bold} caption: | Left: Heatmap summarizing the correlation structure among confound variables. (Cosine bases and PCA-derived CompCor components are inherently orthogonal.) Right: magnitude of the correlation between each confound time series and the mean global signal. Strong correlations might be indicative of partial volume effects and can inform decisions about feature orthogonalization prior to confound regression. subtitle: Correlations among nuisance regressors - bids: {datatype: figures, desc: aroma, suffix: bold} caption: | Maps created with maximum intensity projection (glass brain) with a black brain outline. Right hand side of each map: time series (top in seconds), frequency spectrum (bottom in Hertz). Components classified as signal are plotted in green; noise components in red. subtitle: ICA Components classified by AROMA - name: About reportlets: - bids: {datatype: figures, desc: about, suffix: T1w}
