Aser,
If you you put your custom sequence into SPM, you can get the graphs above. The key variables are: SPM.Sess.U.u, time variable is 0:TR/#oftimebins:TR/#oftimebins*size(SPM.Sess.U.u,1) SPM.xX.X, time variable is 0:TR:TR*size(SPM.xX.X,1), this is the convolved data., this is the stick function or stimulus on times
** Sess will need to be index for each run (e.g. Sess(1).U) ** U will need to be indexed for each condition (e.g. U(1).u, U(2).u)
Hope this helps.

Hi all,
Using the output from OptSeq, is there a possible ( easy ^u^ ) way of plotting in the same graph the presentation of stimuli with their convolution?
So basically, I created my design using OptSeq. To make it nicer, I want to plot this. I am not aware of freesufer and I use SPM. In SPM it just shows the convolved stimuli without showing sticks of the stimuli.
I have attached a picture taken from the genetic program that helps creating or optimizing fMRI designs just to show you what I mean or I want.
I have also attached an excel file contains the output from OptSeq.
Thanks
Aser
