Hi Matthew, I basically want to have one file, that is the concatenation of the RL and LR files and one file with the onsets for the fear and neut conditions for both sessions. For example, subject 100206 has one fear.txt file for each session with the following block onsets:
32.08 18 1 74.223 18 1 116.365 18 1 for the first session and 32.067 18 1 74.21 18 1 116.353 18 1 for the second session Now, after concatenation of the data files, I have to adjust the onsets of the second session, such that all onsets are now greater than the last onset of the first session (116.365). Basically, just add some value to the onsets of the second session. This will depend on the number of "dummy volumes" at the end of the first session and begin of the second session asf. I'm using SPM so I don't think concatenating the design files will work here. Hope it became clear what I mean.
