Correcting for participant error in one run


In one of my runs, the participant missed the start of the first block (1 out of 10) in my 24 s block design in one run. They did initiate a response 17 seconds into the block but the response only lasted 7 seconds (as opposed to 24). The participant did well in all other blocks in all other runs.

Would it be best just not to include this block in the analysis (by taking out the corresponding TRs) or should I just adjust for the duration of the response (using a duration modulated stimulus timing file for this run only)?
