LIPSIA     Thresholding a statistical map
vpretty
The program 'vpretty' thresholds a statistical map and removes small areas.

Example:

vpretty -in zmap.v -pos 3.1 -neg -3.1 -out result.v -minsize 81

The output image displays all activation areas larger than 'minsize'. The parameter '-minsize' is given in units of mm^3. Example: if the spatial resolution is 3x3x3mm then a minsize of 81 corresponds to three voxels (81 = 3 x 27 = 3 x (3x3x3)).

Parameters of 'vpretty':
-help
Prints usage information.
-in
Input file. Default: (none)
-pos
Positive threshold on zmap. Default: 3.09
-neg
Negative threshold on zmap. Default: -3.09
-minsize
Minimal size in mm^3 of activation areas. Default: 81 ( = 3x27 = 3 x (3x3x3)).
