SDM exploration of the results

Thresholding the results

Results from previous calculations can be thresholded to a given probability, a given false discovery rate (FDR) or a given SDM value, obtaining peak coordinates, clusters breakdowns and NIfTI (Analyze-compatible) images. This will also open MRIcron brain viewer to display the results (see Settings section for help on setting up MRIcron integration).

To threshold a map

Press the button [Threshold]

or:

Select [Threshold] in the Statistics menu, to open the following dialog:

Notes

FDR thresholding, as well as SDM value thresholding for maps other than quartiles, must be called from the command-line.

Command-line and batch usage

threshold map, p | fdr | sdm, value, minimum number of voxels

Example:

threshold MyMean, p, 0.001, 10
