Hi Christian,
this is the variable containing the parameters for modulation. The parameters
may be:
I) a vector of equal length as the stimulus onsets, as in:
PM.Sess(1).U(1).name = {'HBSL1stim'};
SPM.Sess(1).U(1).ons = [5.45 6.53 7.49 8.42 9.24]';
SPM.Sess(1).U(1).dur = 0;
SPM.Sess(1).U(1).P(1).name = 'rtacc'
SPM.Sess(1).U(1).P(1).P = [93.67 89.78 99.80 95.90 91.87]';
SPM.Sess(1).U(1).P(1).h = 1; % order of polynomial expansion
ii) or the vector of stimulus onsets if the modulation parameter is time, as
in:
SPM.Sess(1).U(1).name = {'HBSL1stim'};
SPM.Sess(1).U(1).ons = []';
SPM.Sess(1).U(1).dur = 0;
SPM.Sess(1).U(1).P(1).name = 'time'
SPM.Sess(1).U(1).P(1).P = SPM.Sess(1).U(1).ons;
SPM.Sess(1).U(1).P(1).h = 2; % order of polynomial expansion
Best wishes,
Marco
