StatMap

A Matlab structure outputed from imapLMMcontrast or imapLMMmcc. It contains the following fields:

{opt}
Matlab structure, carries information about the statistical values

  • opt.type - model/fixed/random/model beta/predictor beta
  • opt.alpha - default 0.05
  • opt.c - for coefficients and Catepredictors only, cell array containing contrast vector/matrix
  • opt.h - for coefficients and Catepredictors only, cell array containing hypothesis vector/matrix
  • opt.onetail - option to do onetail test, perform on two tail threshold for convenience (alpha/2)
  • opt.name - for coefficients and Catepredictors only, name of each contrast (for plotting)

{Pmap}
P-value map of the preformed linear contrast, not applied when opt.type=model.

{Pmask}
Statistical significant map of the preformed linear contrast, not applied when opt.type=model.

{F/Tmap}
Statistical value map of the preformed linear contrast, not applied when opt.type=model.

{betamap(optional)}
Beta value map of the preformed linear contrast, only applied when the linear contrast is a vector (i.e., Rank=1)

{labels of the maps}
Names of different linear contrasts.

Posthoc

A Matlab structure outputed from imapLMMposthoc. It contains the following fields:

{SelectCluster} A binary map of the data-driven ROI

{DF} degrees of freedom

{beta} A square matrix of all possible pair-wise contrast for Categorical predictors.

{Tval} Statistics (t-value) of the above contrast.

{pval} Statistics (p-value) of the above contrast.

Figure outputs

All output from imapLMMdisplay are saved automatically as .eps files. Other format could be saved manually as the figures will remain open.

Figure output from descriptive_part are saved as .png files.
