[Freesurfer] Paradigm files

Hi Freesurfers,

I am doing some analyses for an experiment where paradigm files were automatically generated by Matlab during stimulus presentation. The script was designed to make paradigm files for an older version of freesurfer, so the files only have 2 columns. I am going to adjust these files so that they can be read by FS 5.3 (add in the extra columns needed).

I noticed that there is a line for each TR as opposed to for the onset of each stimulus, for example, it looks something like this:

0 2 2 2 4 2 6 2 8 1 10 1 12 1 14 3 16 3

instead of

0 2 8 1 14 3

Is this a problem? Can I leave it as is and then just add a column of 2s and a column of 1s?

Thanks!

Emily
