fix: relative and absolute thresholding
Choose SnPM reference version for testing
test: Do not take NaNs into account if ref version < 13.02
fix: Move to test directory before computing tests
test: approx one-sample to keep only 5 sub and 15 perms
Typo
test: keep only 15 perms in slice test
fix: cluster mass display
test: Add snpm reference version in directory name
More efficient computation of permutation indices
fix: More efficient computation of permutation indices
update one-sample test to fit automatically generated data
fix: spm_max can return region labels that are not 1 to max(A)

All one-sample test (except predefined cluster) pass
test: one-subject two conditions to fit automatically generated data
test: two sample with generated test data
fix: use max number of permutations
test: fixe number of betas (in presence of covariates)
test: do not compare two-sample ancova with SPM
test: add (dummy) approximate test
test: anova between with generated test data
