Wrong trials

Hi,
I noticed that the timestamps for incorrect trials are not showing up in the analog data, as if the timing script only sends event codes for successful trials.
Here is the timing script. Is there something that I miss?
Thank you
Anna

Your description of the problem is not sufficient. What are "the timestamps for incorrect trials"? Are you saying that you do not see the timestamps in BHV2 or neural data?

I do not see the timestamps of wrong trials only in the neural data.

thank you

You should describe it better. It is at the end of a trial that you come to know whether the trial is a success or not. However, eventcodes are sent as soon as relevant commands are executed. Most of the time when an eventcode is sent, the success status of a trial is not determined yet. So what do you mean by the timestamps of wrong trials? What are the codes that you do not see?

For example, Code 9 is sent even before a timing script is executed. Are you saying you do not see the 9 (and 18), either, for wrong trials?

Most part of your code is not executed when there is an error in the earlier steps. Is that what you are talking about?

You first should fix the polarity of your strobe signals, before asking about any of these.
