Reports¶
FitLins generates summary reports, written to <output dir>/fitlins/reports/
.
This directory contains a report for each unit of analysis, with visualizations
of design matrices and statistical outputs.

Visualizations¶
Design matrices¶
Examining the design matrix is a quick visual indicator of whether your model was correctly constructed. Task regressors should be predictable, given the study design, and, in the case of this example, we see a clear block design pattern.
Regressor correlation matrices¶
Regressor correlation matrices are provided in order to diagnose collinearities in the design matrix. High correlations among variables of interest or between variables of interest and nuisance regressors are cause for concern, as the GLM will not be able to distinguish signal attributable to one regressor from that attributable to a collinear regressor.
Contrast matrices¶
Glass brain plots¶
Naming decisions¶
For reporting purposes, FitLins performs some minor reformatting of contrast
names.
If _gt_
is found, for example, FitLins will display it in the report
document (although not the figures) as >
.
Similarly, _lt_
and _vs_
become <
and “vs.”, respectively.
See the example report for examples.
