The invention provides a method of automatically calculating a linking strength of brain fiber tracts. The method includes the steps as follows: providing a brain reference template with a plurality of reference fiber bundles; providing an object image with an image information; co-registering the image information according to the brain reference template, deforming and mapping the reference fiber bundles on the object image, so as to make the object image have a plurality of clear object fiber bundles; defining a plurality of regions of interest (ROIs) from the object image, analyzing and calculating a number and a length of the object fiber bundles between each two ROIs, and obtaining a plurality of mean object information from connections between the ROIs; dividing the number by the length, and then multiplying a value above by the mean object information to generate a plurality of link strength values of connections between the ROIs used to be made as a matrix image.
