As a further illustration, the below syntax only gives partial eta for the
overall or omnibus ANOVA. I want the partial eta for each contrast (probably
can do in head, but for the time being let us proceed).

  UNIANOVA Y1 BY FACTOR1
  /CONTRAST(FACTOR1)=SPECIAL(1 0 -1)
  /METHOD=SSTYPE(3)
  /INTERCEPT=INCLUDE
  /POSTHOC=FACTOR1(LSD BONFERRONI T2)
  /PLOT=PROFILE(FACTOR1) TYPE=BAR ERRORBAR=CI MEANREFERENCE=YES
  /PRINT ETASQ DESCRIPTIVE HOMOGENEITY OPOWER
  /CRITERIA=ALPHA(.05)
  /DESIGN=FACTOR1.
