When correcting for multiple comparisons using:

mri_glmfit-sim \
  --glmdir lh.gender_age.glmdir \
  --sim mc-z 5 4 mc-z.negative \
  --sim-sign neg --cwpvalthresh 0.4\
  --overwrite
What does the sign mean (ie - the neg, pos, abs). Also for the mc-z simulation type do we no longer need to include the smoothness of our data (FWMH)?
