[Eeglablist] Question about false discovery rate

Dear EEGLABers,
    I am interested in using false discovery rate (FDR) to control for
multiple comparisons and have a couple of questions:
1) What is the version of FDR control used by EEGLAB's fdr.m (written by
Delorme & Nichols).  Could you give me a citation?

2) FDR correction assumes that the measurements in each comparison are
independent or "positively dependent."   What does "positively dependent"
mean?  I am applying FDR correction to EEG data and the results of the
different comparisons are surely not independent.  Are they likely to be
positively dependent?

    thank you for your time,
           Wambua
