Notch filter error

Hi, I am putting my noise run MEG files through notch filter, but I get an error saying "Index exceeds the number of array elements (310)" and a 'closed'/empty folder with _notch in the name. What may be my problem?

Thanks so much.

Hi @hchoi, there seems to be something strange in your database, there should be a channel file (iconChannel) associated with the raw data (before the notch) but it is not there in your database.

Can you provide more details on how are you reviewing this raw file?

Hi, we figured out that it was a simple mistake. For some reason (that we need to investigate), our default protocol/subject setting (individual anatomy, one channel file per acquisition run) were changed. When we reverted back to our default setting, problem was resolved. Thank you
