Statistics in ROI - generic

Computes simple statistics on one or more images from region of interest.

Description

This process allows to compute simple statistics in images according to a mask or a set of labels. Several images can be used as input, but only one ROI file can be used at a time.

Images and ROI files have to be in the same space to return meaning values (ex: in MNI space).

Features computed

For each label in the ROI image, several values are output by the process:

• mean of the values in the ROI
• volume of the ROI
• the median value in the ROI
• the standard deviation (stddev) of the image in the ROI
• minimum value of the image in the ROI
• maximum value of the image in the ROI
• the total value of the image measured in the ROI (point_count)
