Is it really only returning the maximum probability or minimum statistic across a bunch of files?

It would be trivial to implement a process that does this in Brainstorm.

  • Select 2 or more stat files in Process1

  • For each file f:

    • If Conj is not defined:
      • Conj = f.pmap
    • Else:
      • Conj(f.pmap > Conj) = f.pmap(f.pmap > Conj)

  • Or for minimum statistic:

    • If Conj is not defined:
      • Conj = f.tmap
    • Else:
      • Conj(f.tmap < Conj) = f.tmap(f.tmap < Conj)

  • Or since we store both in Brainstorm files (pmap and tmap) it would be easier to compute the two at once:

    • Conj.pmap(f.pmap > Conj.pmap) = f.pmap(f.pmap > Conj.pmap)
    • Conj.tmap(f.tmap < Conj.tmap) = f.tmap(f.tmap < Conj.tmap)

Does this make sense?
