 ### Active Questions
 - Some fiber photometry sessions (ex. FP_RR20_96.259_2019-04-17T16-03-52) have msns that I was told to skip (ex. RR20_Right_AHJS)
   Should I still skip these, or just treat them like RR20Right?
+- In one of those sessions, FP Experiments/Photometry/RR20/late/Photo_96_259-190506-105642, doesn't have any RNnR TTLs,
+  even though it has plenty of right nose pokes in the behavioral file. Can you look into this?
