Description of the problem:
Hello,
I am working on an experiment where participants classify a given duration as being closer to a short or long (previously learned) reference duration. I retrieve the stimulus durations from an excel file which has 100 rows of durations. However, when I look at the data, I see that the experiment saves 99 of them, as if there are 99 trials. The data files look quite messy anyways, which makes it really hard to navigate in the csv file and having missing data makes it extra frustrating… 
Is there anybody else experiencing the same issue? is there any solution for the missing data save?
thank you so much in advance, tutku
