WebThere is an SPM12 manual distributed with the software (spm12/man/manual.pdf), which is written by the developers. Much of the manual's contents are also available via the SPM batch interface. See also the release notes. Manuals for SPM8,SPM5 and SPM99 (roughly applicable for SPM2) are also available. Books WebA good guideline to follow is to use Bonferroni correction based on the number of ROIs that you test; e.g, if you test two ROIs, then divide the p-value by 2, for a corrected alpha level of 0.025.)
